If such person fails to apply or become licensed or qualified or is found unsuitable, we shall have the right, at our option, to either require such person to dispose of its notes or beneficial interest therein, or redeem such notes.

Risk Factors		Please read the section entitled "Risk Factors" beginning on page S-5 of this prospectus supplement for a discussion of some of the factors you should carefully consider before deciding to invest in the notes.

You should carefully consider the risks described below in addition to the remainder of this prospectus supplement and the factors discussed in our public filings with the SEC, including the information provided under the caption "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended September 30, 2012, filed with the SEC on November 28, 2012 and our Quarterly Reports on Form 10-Q for the quarters ended December 31, 2012, March 31, 2013 and June 30, 2013, filed with the SEC on February 6, 2013, May 8, 2013 and August 2, 2013, respectively, and incorporated by reference herein, and subsequent periodic filings with the SEC, before making an investment decision. The risks and uncertainties described below and incorporated by reference in this prospectus supplement are not the only ones related to our business, the notes or the offering. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially and adversely affect our business operations, results of operations, financial condition, liquidity or prospects. The trading price of the notes could decline due to the occurrence of any of these risks, and you may lose all or part of your investment.

Our holding company structure results in structural subordination and may affect our ability to make payments on the notes.

We are a holding company and conduct substantially all of our operations through our subsidiaries who own substantially all of our consolidated assets. Consequently, our cash flow and our ability to make payments on our indebtedness, including the notes, substantially depends upon our subsidiaries' cash flow and payments of funds to us by our subsidiaries. Our subsidiaries are not obligated to make funds available to us for payment on the notes or otherwise. Our subsidiaries' ability to make any payments will depend on their earnings, the amount and the terms of their indebtedness, business and tax considerations and legal restrictions.

The notes are exclusively obligations of IGT and not of any of our subsidiaries, and will be structurally subordinated to all existing and future obligations, including trade payables, of our subsidiaries. In addition, the indenture governing the notes will not restrict our subsidiaries' ability to incur additional indebtedness, including a certain amount of secured indebtedness. In the event of a bankruptcy, liquidation or dissolution of a subsidiary, the creditors of such subsidiary will be paid first, after which the subsidiary may not have sufficient assets remaining to make any payments to us as a shareholder or otherwise so that we can meet our obligations under the notes.

As of June 30, 2013, our total consolidated balance sheet liabilities, including liabilities of all majority-owned subsidiaries and variable interest entities for which we are the primary beneficiaries were approximately $2,826.9 million, of which approximately $435.8 million were jackpot liabilities offset on a dollar for dollar basis by U.S. Treasury securities, "Agency" securities (such as those issued by Freddie Mac and Fannie Mae) and cash. As of June 30, 2013, the total balance sheet liabilities on an unconsolidated basis of our subsidiaries were approximately $946.7 million.

The notes will not be secured by any of our assets and our secured debt will have claims with respect to the secured assets superior to the notes.

The notes will not initially, and are not expected in the future to, be secured by any of our assets. If at any time in the future we are required to grant a lien on our assets securing any of the 3.25% convertible notes due 2014 issued and sold by us in May 2009, the 7.50% notes due 2019 issued and sold by us in June 2009, or the 5.500% notes due 2020 issued and sold by us in June 2010 (collectively, the "Existing Notes"), we will also be required (as described under "Description of Notes—Future Liens") to grant an equal and ratable lien in favor of the notes. However, there can be no assurance that a lien granted in favor of any Existing Notes will also be granted on an equal and ratable basis in favor of the notes or will be enforceable as to the notes (including, without limitation, because we fail

to obtain any required regulatory approval). In addition, we may issue secured indebtedness in the future that would not require us to grant a lien securing any Existing Notes or the notes. To the extent that a lien on our assets is not also granted on an equal and ratable basis in favor of the notes or is not enforceable as to the notes, the notes will be effectively subordinated to such secured indebtedness to the extent of the collateral securing such indebtedness. If we become insolvent or are liquidated, or if payment of any secured indebtedness is accelerated, the holders of such secured indebtedness will be entitled to exercise the remedies available to secured lenders under applicable law, including the ability to foreclose on and sell the assets securing such indebtedness in order to satisfy such indebtedness. In any such case, any remaining assets may be insufficient to repay the notes and our other unsecured indebtedness. In addition, any collateral that secures the notes may not be sufficient to pay all or any amounts due on the notes. Any claim for the difference between any amount realized from the sale of collateral securing the notes and obligations under the notes will rank equal in right of payment with all of our other unsecured unsubordinated indebtedness, including trade payables.

We may require you to dispose of your notes, or redeem your notes, if required by applicable gaming regulations.

Certain gaming authorities may, in their discretion, require the holder of any of our securities, at such holder's own expense, to file applications, be investigated and be found suitable to own such securities. Any person who fails or refuses to apply for a finding of suitability or a license within 30 days after being ordered to do so by such gaming authorities may be found unsuitable. Under certain circumstances, we have the right, at our option, to cause a holder to dispose of its notes or to redeem such holder's notes in order to comply with gaming laws to which we are subject. See "Description of Notes—Mandatory Disposition Pursuant to Gaming Laws."

The notes do not restrict our ability to incur additional debt or to take other actions that could negatively impact holders of the notes.

We are not restricted under the terms of the indenture and the notes from incurring additional indebtedness, including indebtedness under our senior credit facility, or securing any of our indebtedness. In addition, the notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. Our ability to recapitalize, incur additional debt, secure existing or future debt and take a number of other actions that are not limited by the terms of the indenture and the notes could have the effect of diminishing our ability to make payments on the notes when due. In addition, we are not restricted from repurchasing any indebtedness, including subordinated indebtedness, by the terms of the indenture and the notes. If we issue other debt securities in the future, our debt service obligations will increase.

Noteholders may not be able to accelerate the maturity of the notes if we fail to make our SEC filings in a timely manner.

The indenture governing the notes will require us to furnish our SEC filings to the trustee (as defined below) no more than 15 days after the date on which we file them with the SEC. The indenture also requires us to comply with certain filing requirements as set forth in the Trust Indenture Act of 1939, as amended. If we fail to furnish such reports to the trustee, or we fail to comply with such filing requirements, we will be required to pay additional interest during the 60-day period after the date they were due, and during such period, holders of the notes will not be able to accelerate the maturity of the notes. The indenture does not contain other reporting requirements with the SEC on our part. Accordingly, holders of the notes may not be able to accelerate the maturity of the notes if we fail to make our SEC filings in a timely manner. See "Description of Notes—Reports."

We may not have the ability to repurchase the notes upon a change of control.

If a change of control repurchase event occurs, holders of the notes may require us to repurchase, for cash, all or a portion of their notes. We may not have sufficient funds to pay the interest or principal on the notes or the repurchase price. In addition, our senior credit facility or other agreements in effect at the time of the change of control may restrict our ability to make cash payments in connection with the repurchase of the notes upon a change of control repurchase event if an event of default then exists or would result from such payment under such agreements. If we fail to pay interest on the notes or repurchase the notes, we will be in default under the indenture governing the notes.

Some significant transactions may not constitute a change of control repurchase event that would obligate us to offer to repurchase the notes.

Because the term "change of control repurchase event," as defined in the indenture governing the notes, is limited to certain specified transactions, it may not include other events that might adversely affect our financial condition or the market price of the notes in all cases. In addition, an event that is a change of control may occur but, absent a ratings downgrade below an investment grade rating by not less than two rating agencies within a specific period, would not give the holders of the notes a right to require us to repurchase the notes. Furthermore, certain other transactions such as leveraged recapitalizations, refinancings, restructurings or certain acquisitions of other entities by us or our subsidiaries would not constitute a change in control.

A downgrade, suspension or withdrawal of the rating assigned by a rating agency to our long-term senior debt or the notes, or changes in the financial and credit markets, could cause the liquidity or market value of the notes to decline significantly.

Our long-term senior debt is rated, and we expect that the notes will be rated, by one or more rating agencies. Any rating so assigned may not remain for any given period of time or a rating may be lowered or withdrawn entirely by a rating agency if, in that rating agency's judgment, future circumstances relating to the basis of the rating, such as adverse changes in our business, so warrant.

In addition, the financial and credit markets have recently experienced significant turmoil. The condition of the financial and credit markets and prevailing interest rates have fluctuated in the past and are likely to fluctuate in the future. Any ratings downgrade of our long-term debt or the notes or further disruptions in the financial and credit markets and future fluctuations in these markets and prevailing interest rates may have an adverse effect on the market value of the notes.

The notes are a new issue of securities for which there is no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes on any automated dealer quotation system. As a result, an active trading market for the notes may not develop and any such market, if it were to develop, may not be liquid or sustainable for any period of time. Future trading prices of the notes will depend on many factors, including, among other things, prevailing interest rates, the then-current ratings assigned to the notes, the market for similar securities and our performance. Any trading market that develops would be affected by many factors independent of and in addition to the foregoing, including:

The underwriters have advised us that they currently intend to make a market in the notes, but they are not obligated to do so and may cease market-making at any time without notice, which could further negatively impact your ability to sell the notes or the prevailing market price at the time you choose to sell.

We estimate that the proceeds to us from this offering will be approximately $ million, after payment of the underwriting discount and estimated offering expenses to be paid by us.

We intend to use the net proceeds of this offering for general corporate purposes. In addition, we intend to use any previously unused net proceeds from this offering to redeem a portion of our 3.25% convertible notes due 2014 at maturity on May 1, 2014.

Our 3.25% convertible notes due 2014 bear interest at a rate of 3.25% per annum and will mature on May 1, 2014. As of June 30, 2013, $850.0 million aggregate principal amount of our 3.25% convertible notes due 2014 were outstanding. Because the application of the net proceeds to us from this offering will not be sufficient to redeem all of our 3.25% convertible notes due 2014 at maturity, we will fund the balance from cash on hand or borrowings under our senior credit facility.

The following table sets forth the cash and cash equivalents position and the consolidated capitalization of IGT as of June 30, 2013:

This table should be read in conjunction with the financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended September 30, 2012 and in our Quarterly Report on Form 10-Q for the quarter ended June 30, 2013, which are incorporated by reference herein.

The table below sets forth the ratio of earnings to fixed charges of IGT and its consolidated subsidiaries on a historical basis for each of the periods indicated:

For the purpose of computing this ratio, earnings represent income from continuing operations before fixed charges and income taxes. Fixed charges represent interest expense, excluding the portion related to jackpot liabilities and including capitalized interest, one-third of total rental expense (which represents a reasonable approximation of the interest factor), and amortization of discounts/premiums and capitalized costs related to debt.

We will issue the notes under a third supplemental indenture to be dated as of the closing date of this offering to the indenture dated as of June 15, 2009 (together, the "indenture") between us and Wells Fargo Bank, National Association, as trustee (the "trustee"). The following description of the terms of the indenture and the notes is a summary. This summary does not restate the indenture or the notes in full and excludes certain definitions and legal terminology contained in the indenture. While we believe this summary contains all of the information about the indenture important to your decision to purchase the notes, it does not include all of the provisions of the indenture. We urge you to read the indenture because it, and not this summary, will define your rights as a holder of notes. You may request a copy of the indenture from the trustee or from us at our address shown under "Where You Can Find More Information," and we will file a copy of the indenture with the SEC.

If this description differs in any way from the description of the debt securities in the accompanying prospectus, then you should rely on this description.

In this section, references to "IGT," "we," "our" or "us" refer solely to International Game Technology and not its subsidiaries.

The notes will be issued in an aggregate principal amount of $ . However, we may, without the consent of the holders of the notes, issue additional debt securities having the same ranking, interest rate, maturity, redemption provisions and other terms as the notes. Any additional debt securities having the same terms, together with the notes, will constitute a single series under the indenture.

The entire principal amount of the notes will mature and become due and payable, together with any accrued but unpaid interest thereon, on , 2023. The notes will bear cash interest at the rate of % per annum from the original issuance date of the notes. We will pay interest on the notes semi-annually in arrears on and of each year, commencing on , 2014, to holders of record at the close of business on the or (as the case may be) immediately preceding such interest payment date. Interest will be calculated using a 360-day year composed of twelve 30-day months. Each payment of interest on the notes will include interest accrued for the period commencing on and including the immediately preceding interest payment date (or, in connection with the initial interest payment date, the original issuance date) to but excluding the applicable interest payment date (or repurchase or maturity date, as applicable).

Any payment required to be made on any day that is not a business day will be made on the next succeeding business day and no additional interest or other amount will be paid as a result of any such postponement. A "business day" is any weekday that is not a day on which banking institutions in The City of New York are authorized or required by law to close. Interest will cease to accrue on a note upon its maturity, redemption or repurchase by us.

We may, to the extent permitted by applicable law, at any time repurchase the notes in the open market or by tender at any price or by private agreement, in each case in our sole discretion.

The notes will be payable at the corporate trust office of the paying agent, which initially is an office or agency of the trustee. We may change the paying agent or registrar without prior notice to the holders of the notes, and we or any of our subsidiaries may act as paying agent or registrar. So long as the notes are represented by a global security, the interest payable on the notes will be paid to Cede & Co., as nominee of DTC, or its registered assigns as the registered owner of such global security, by wire transfer of immediately available funds on each interest payment date.

The notes will be issued in fully registered form only in minimum denominations of $2,000 principal amount and multiples of $1,000 principal amount in excess thereof.

We do not intend to apply to list the notes on any securities exchange or to have the notes quoted on any automated quotation system.

The notes will be our unsecured and unsubordinated obligations and will rank senior to all of our existing and future subordinated indebtedness and will rank equal in right of payment with our existing and future unsecured and unsubordinated obligations. The notes will be structurally subordinated to all existing and future obligations, including trade payables, of our subsidiaries and, except in the circumstances described under "Description of Notes—Future Liens," will be effectively subordinated to any of our secured indebtedness to the extent of the collateral securing such indebtedness. None of our subsidiaries is or is required to become a guarantor of the notes.

We currently conduct substantially all of our operations through our subsidiaries and our subsidiaries generate substantially all of our operating income and cash flow. As a result, distributions and advances from our subsidiaries are the principal source of funds available to meet our debt service obligations. Contractual provisions or laws, as well as our subsidiaries' financial condition and operating and regulatory requirements, may limit our ability to obtain cash from our subsidiaries that we require to pay our debt service obligations, including payments on the notes. In the event of a bankruptcy, liquidation or dissolution of a subsidiary, the creditors of that subsidiary will be paid first, after which it may not have sufficient assets remaining to make any payments to us as a shareholder or otherwise so that we can meet our obligations under the notes.

Other than restrictions described under "—Change of Control Repurchase Event" and "—Merger and Sale of Assets by IGT" below, the indenture does not contain any covenants or other provisions designed to afford holders of the notes protection in the event of a highly leveraged transaction involving us or in the event of a decline in our credit rating as the result of a takeover, recapitalization, highly leveraged transaction or similar restructuring involving us that could adversely affect such holders.

The notes will be redeemable at our option in whole, at any time, or in part, from time to time, at a redemption price equal to the greater of:

plus, in each case, any accrued but unpaid interest on the notes being redeemed to, but excluding, the date of redemption; provided, however, that installments of interest on the notes that are due and payable on an interest payment date falling on or after a redemption date occurring after the related record date will be payable on such interest payment date to the registered holders as of the close of business on the relevant record date.

Notwithstanding the foregoing, if the notes are redeemed on or after 90 days prior to the maturity date, the redemption price will be equal to 100% of the principal amount of the notes to be redeemed, plus any accrued but unpaid interest thereon to, but excluding, the date of redemption.

We will mail or send by electronic transmission notice of any redemption at least 30 days but not more than 60 days before the redemption date to each holder of the notes to be redeemed at its registered address. Once notice of redemption is mailed, the notes called for redemption will become due and payable on the redemption date at the redemption price. In addition, we will issue a press release containing the relevant information included in the notice (and make the press release available on our website).

Unless we default in payment of the redemption price and accrued but unpaid interest, if any, on and after the redemption date interest will cease to accrue on the notes or portions of the notes called for redemption.

In the case of a partial redemption, selection of the notes for redemption will be made by lot or by such other method as the trustee in its sole discretion deems fair and appropriate (subject to the procedures of DTC). No notes of a principal amount of $2,000 or less will be redeemed in part. If any note is to be redeemed in part only, the notice of redemption that relates to the note will state the portion of the principal amount of the note to be redeemed. In the case of a physical certificate, a new note in a principal amount equal to the unredeemed portion of the note will be issued in the name of the holder of the note upon surrender for cancellation of the original note.

Upon the occurrence of a change of control repurchase event (as defined below), unless we have exercised our right to redeem the notes as described under "—Optional Redemption," each holder of the notes will have the right to require us to repurchase all, or any portion (although no notes of a principal amount of $2,000 or less will be repurchased in part), of its notes pursuant to the offer described below (the "change of control offer"), at a purchase price equal to 101% of the then-outstanding principal amount thereof plus accrued but unpaid interest to, but excluding, the date of repurchase (such price, the "change of control repurchase price"), subject to the rights of holders of the notes on any relevant record date to receive interest due on the relevant interest payment date.

Within 30 days following the date upon which the change of control repurchase event occurred or, at our option, prior to any change of control (as defined below) but after the public announcement of that pending change of control, we will be required to send, by first class mail, or by electronic transmission in the case of notes held in book-entry form, a notice to each holder, with a copy to the trustee, which notice will govern the terms of the change of control offer. That notice will state, among other things, the repurchase date, which must be no earlier than 30 days nor later than 60 days from the date such notice is mailed to the holders, other than as may be required by law (the "change of control payment date") and will specify the procedures for tendering notes. If mailed prior to the date of consummation of the change of control, the notice will state that the change of control offer is conditioned on the consummation of the change of control on or prior to the change of control payment date, provided that a change of control offer may only be made in advance of a change of control repurchase event and be conditional on such change of control repurchase event if a definitive agreement is in place for a change of control at the time such conditional change of control offer is made. In addition, we will issue a press release containing the relevant information included in the notice (and make the press release available on our website).

Holders who elect to have their notes repurchased pursuant to a change of control offer will be required to surrender their notes, together with any required instructions, to the paying agent at the address specified in the notice, or to transfer their notes to the paying agent by book-entry transfer pursuant to the applicable procedures of the paying agent and DTC, prior to the close of business on the third business day immediately preceding the change of control payment date.

The paying agent will promptly distribute to each holder of the notes properly tendered the change of control repurchase price for such notes, and we will execute, and the authenticating agent will promptly authenticate and deliver (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any notes tendered, provided that each new note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any note so accepted will cease to accrue interest on and after the change of control payment date.

We will not be required to make a change of control offer if (i) a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements that we would have been required to meet had we made such an offer, and (ii) such third party purchases all the notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any notes if there has occurred and is continuing on the change of control payment date an event of default under the indenture, other than a default in the payment of the change of control repurchase price upon a change of control repurchase event.

We will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the notes as a result of a change of control repurchase event. We will comply with these rules to the extent they apply at that time.

The definition of change of control includes a phrase relating to the conveyance, transfer, sale, lease or disposition of "all or substantially all" of our and our subsidiaries' assets. Although there is a

developing body of case law interpreting the phrase "substantially all," there is no precise, established definition of the phrase under applicable law. Accordingly, the ability of a holder to require us or a third party to repurchase its notes as a result of the conveyance, transfer, sale, lease or other disposition of less than all of IGT's and its subsidiaries' assets may be uncertain.

The foregoing provisions would not necessarily provide the holders of the notes with protection if we are involved in a highly leveraged or other transaction that may adversely affect the holders.

If a change of control repurchase event were to occur, we may not have sufficient funds to pay the change of control repurchase price for all or any of the notes that are surrendered to us. See "Risk Factors—Risk Factors Related to the Notes—We may not have the ability to pay interest on the notes, to pay amounts due at maturity or to repurchase the notes upon a change of control." In particular, we have, and may in the future incur, other indebtedness with similar or stricter change of control provisions permitting our holders to accelerate or to require us to repurchase our indebtedness upon the occurrence of similar events or on some specified dates. If we fail to repurchase the notes when required following a change of control repurchase event, we will be in default under the indenture governing the notes.

Under the indenture, we will not, and will not permit any of our restricted subsidiaries (as defined below) to, incur, issue, assume or guarantee any indebtedness (as defined below) secured by any lien, other than permitted liens (as defined below), on (1) any property or assets owned or leased by us or any restricted subsidiary or (2) any shares of stock or debt of any restricted subsidiary, unless we secure the notes equally and ratably with, or prior to, the indebtedness secured by the lien, for so long as such other indebtedness is so secured. If we secure the notes in this manner, we have the option of securing any of our other indebtedness or obligations, or those of any subsidiary, equally and ratably with the notes, as long as such other debt or obligations are not subordinate to the notes.

Notwithstanding the foregoing, IGT may, and may permit any of its restricted subsidiaries to, incur liens securing indebtedness without equally and ratably securing the notes if, after giving effect to the incurrence of such liens, the aggregate amount (without duplication) of (a) the aggregate principal amount of the indebtedness secured by such liens (other than permitted liens) on the property or assets (which includes capital stock) of IGT and its restricted subsidiaries plus (b) all attributable indebtedness of IGT or any restricted subsidiary in respect of any sale and leaseback transaction, is in aggregate less than or equal to 10% of our consolidated net tangible assets.

The foregoing restriction does not apply to the following (each, a "permitted lien"):

Neither we nor any of our restricted subsidiaries will enter into, assume, guarantee or otherwise become liable with respect to a sale and leaseback transaction unless after giving effect thereto the sum, without duplication, of: (a) the aggregate principal amount of all secured indebtedness (other than to the extent secured by a permitted lien); and (b) all attributable indebtedness in respect of sale and leaseback transactions (other than those referred to in the following paragraph), does not in the aggregate exceed 10% of our consolidated net tangible assets.

This restriction shall not apply to any sale and leaseback transaction if, within one year from the effective date of such sale and leaseback transaction, we or a restricted subsidiary apply to (1) the purchase, construction or improvement of other property used or useful in the business of, or other capital expenditure by, us or any of our restricted subsidiaries or (2) the retirement of long-term debt (as defined below) or the prepayment of any capital lease obligation of us or any restricted subsidiary, an amount of cash not less than the greater of (a) the net proceeds of the sale of the property sold and leased back pursuant to such arrangement, or (b) the fair market value of the property sold and leased back pursuant to such arrangement, provided that the amount to be applied or prepaid shall be reduced by (x) the principal amount of any notes delivered within one year after such sale to the trustee for retirement and cancellation, and (y) the principal amount of our long-term debt (including, for this purpose, any currently maturing portion of such long-term debt), other than the notes, voluntarily retired by us or any restricted subsidiary within one year after such sale.

This restriction also does not apply to any sale and leaseback transaction between us and any of our restricted subsidiaries or between any of our restricted subsidiaries, or for which, at the time the transaction is entered into, the term of the related lease to us or our restricted subsidiary of the property sold pursuant to such transaction is three years or less.

"Long-term debt" means all indebtedness for borrowed money owed or guaranteed by us or any of our subsidiaries and any other indebtedness which, under GAAP, would appear as indebtedness on our most recent consolidated balance sheet, which matures by its terms more than 12 months from the date of such consolidated balance sheet or which matures by its terms in less than 12 months but by its terms is renewable or extendible beyond 12 months from the date of such consolidated balance sheet at the option of the borrower.

We will agree in the indenture that if at any time we are required to grant a lien to the holders of any of the 3.25% convertible notes due 2014 issued and sold by us in May 2009, the 7.50% notes due 2019 issued and sold by us in June 2009, or the 5.500% notes due 2020 issued and sold by us in June 2010, excluding, in each case, any refinancings, refundings, replacements, renewals or extensions thereof (collectively, the "Existing Notes"), then we will grant to the trustee, on behalf of all holders of the notes, an equal and ratable lien on any of our assets or the assets of our subsidiaries that are subject to any such lien granted to the holders of the Existing Notes. If, thereafter, any such lien is released pursuant to the terms of the indentures governing the Existing Notes, then the lien in favor of the trustee will similarly be released; provided, that if any lien in favor of the holders of the Existing Notes is then subsequently reimposed under the terms of the indentures governing the Existing Notes, we shall again grant an equal and ratable lien in favor of the trustee.

Any such lien in any collateral granted hereunder is expected to be shared equally and ratably with the Existing Notes; provided, that any such lien shall be automatically released upon the release of the lien discussed above.

We may not (1) consolidate with or merge into any other person or sell, convey, lease or transfer our properties and assets substantially as an entirety to any other person in any one transaction or series of related transactions, or (2) permit any person to consolidate with or merge into us, unless

This covenant shall not apply to sale, assignment, transfer, conveyance or other disposition of assets between or among us and any restricted subsidiary.

Upon any such consolidation, merger or transfer, the surviving person (if not us) shall succeed to, and may exercise every right and power of, IGT under the indenture.

Although these types of transactions are permitted under the indenture, certain of the foregoing transactions could constitute a change of control which, if such transaction causes a change of control repurchase event, would enable holders to require us to repurchase their notes as described above.

Each holder, by accepting notes, shall be deemed to have agreed that if the gaming authority of any jurisdiction in which we or any of our subsidiaries does business requires that a person who is a holder or the beneficial owner of notes be licensed, qualified or found suitable under applicable gaming laws, such holder or beneficial owner, as the case may be, shall apply for a license, qualification or a finding of suitability within the required time period. If such person fails to apply or become licensed or qualified or is found unsuitable, we shall have the right, at our option:

We shall notify the trustee in writing of any such redemption as soon as practicable. We shall not be responsible for any costs or expenses any such holder may incur in connection with its application for a license, qualification or a finding of suitability. In addition, if any notes are held in trust by an agent or by a nominee, the record holder of any notes may be required to disclose the identity of the beneficial owner of any notes to gaming authorities. A failure to make such disclosure may be grounds for finding the record holder unsuitable. We are also required to render maximum assistance in determining the identity of the beneficial owner.

So long as any notes are outstanding, we will furnish to the trustee within 15 days after the date on which we file the same with the SEC pursuant to its rules and regulations, all annual and quarterly reports, information, documents and other reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act.

If at any time we are not subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, we will provide the trustee with annual and quarterly reports containing substantially the same information as would have been required to be filed with the SEC had we continued to have been subject to such reporting requirements. In such event, such annual and quarterly reports shall be provided at the times we would have been required to provide reports had we continued to have been subject to such reporting requirements. We will also comply with the other provisions of Section 314(a) of the Trust Indenture Act of 1939, as amended (the "Trust Indenture Act").

Notwithstanding the foregoing, the indenture will provide that, to the extent elected by us, the sole remedy for an event of default described in the 6th bullet above relating to the failure to file any documents or reports that we are required to file with the SEC pursuant to Section 13 or 15(d) of the Exchange Act or as otherwise required to be filed pursuant to the indenture and for any failure to comply with the requirements of Section 314(a)(1) of the Trust Indenture Act, will for the first 60 days after the occurrence of such an event of default consist exclusively of the right to receive additional interest on the notes at an annual rate equal to 0.25% of the principal amount of the notes (the "extension fee"). The extension fee will accrue on all outstanding notes from and including the date on which an event of default relating to a failure to comply with the reporting obligations in the indenture first occurs to but not including the 60th day thereafter (or such earlier date on which the event of default relating to the reporting obligations shall have been cured or waived). On such 60th day (or earlier, if the event of default relating to the reporting obligations is cured or waived prior to such 60th day), such extension fee will cease to accrue and, if the event of default relating to reporting obligations has not been cured or waived prior to such 60th day, the notes will be subject to acceleration as provided herein. The provisions of the indenture described in this paragraph will not affect the rights of holders of the notes in the event of the occurrence of any other event of default. In the event that we do not elect to pay the extension fee upon an event of default in accordance with this paragraph, the notes will be subject to acceleration as provided herein. To make such election, we must give notice to the trustee for holders prior to the day any such event of default occurs.

The indenture requires that we file annually with the trustee a certificate describing any default by us in the performance of any conditions or covenants that has occurred under the indenture and its status. We must give the trustee written notice within 30 days of any default under the indenture and any event that with the giving of notice or the lapse of time would become an event of default under the indenture.

The indenture provides that if an event of default occurs and is continuing with respect to the notes, either the trustee or the registered holders of at least 25% in aggregate principal amount of the notes may declare the principal amount plus accrued but unpaid interest, if any, on the notes to be due and payable immediately. If an event of default relating to some events of bankruptcy, insolvency or reorganization occurs, the principal amount plus accrued but unpaid interest, if any, on the notes will become immediately due and payable without any action on the part of the trustee or any holder. At any time after a declaration of acceleration, but before a judgment or decree for payment of money has been obtained, if all events of default with respect to the notes have been cured (other than the nonpayment of principal of the notes which has become due solely by reason of the declaration of

acceleration), then the registered holders of a majority in aggregate principal amount of notes may rescind the declaration of acceleration.

This provision does not, however, affect the right of a holder of notes to sue for enforcement of payment of the principal of or interest on the holder's notes on or after the respective due dates expressed in its notes.

The trustee is entitled under the indenture, subject to the duty of the trustee during a default to act with the required standard of care, to indemnification reasonably satisfactory to it before proceeding to exercise any right or power under the indenture at the direction of the registered holders of the notes. None of the trustee's duties and powers under the indenture requires it to expend or risk its own funds or otherwise incur any financial liability. The indenture also provides that the registered holders of a majority in principal amount of the outstanding notes may direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the notes. The trustee, however, may refuse to follow any such direction that conflicts with law or the indenture, is unduly prejudicial to the rights of other registered holders of the notes, or would involve the trustee in personal liability.

The indenture provides that, while the trustee generally must mail notice of a default or event of default to the registered holders of the notes within 90 days of occurrence, the trustee may withhold notice of any default or event of default (except in payment on the notes) if the trustee in good faith determines that the withholding of such notice is in the interest of the registered holders of the notes.

We may amend or supplement the indenture if the holders of a majority in principal amount of the notes consent to it. Without the consent of the holder of each note affected thereby, however, no modification may:

We may amend or supplement the indenture or waive any provision of it without the consent of any holders of the notes in some circumstances, including:

The holders of a majority in principal amount of the outstanding notes generally may waive any existing or past default or event of default. Those holders may not, however, waive any default or event of default in any payment on any note or compliance with a provision that cannot be amended or supplemented without the consent of each holder affected.

The consent of the holders is not necessary under the indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment under the indenture becomes effective, we are required to mail to the holders a notice briefly describing such amendment. However, with respect to amendments that do not require the consent of holders of the notes, the failure to give such notice to all the holders, or any defect in the notice, will not impair or affect the validity of the amendment.

We may satisfy and discharge our obligations under the indenture by delivering to the registrar for cancellation all outstanding notes or, subject to the satisfaction of certain conditions contained in the indenture and within one year of the maturity date of the notes, by irrevocably depositing with the trustee or delivering to the holders, as applicable, cash sufficient to pay all of the outstanding notes and all other sums payable under the indenture by us. Such discharge is subject to terms contained in the indenture.

We may be discharged from all of our obligations with respect to the notes (except for the rights of holders to receive payments of principal and any premium or interest solely from funds deposited in trust, and certain obligations to exchange or register the transfer of notes, to replace stolen, lost or mutilated notes, to maintain paying agencies, to hold moneys for payment in trust and to defease and discharge notes as provided in the indenture). To be discharged from those obligations, we must irrevocably deposit in trust for the benefit of the holders of the notes money or government obligations, or both, which, through the payment of principal of and interest on the deposited money or

government obligations, will, in the opinion of a nationally recognized firm of independent certified public accountants, provide enough money to pay the principal of and any premium and interest on the notes on the final maturity date in accordance with the terms of the indenture and the notes. We may only do this if, among other things, we have delivered to the trustee an opinion of counsel to the effect that we have received from, or there has been published by, the Internal Revenue Service a ruling, or there has been a change in tax law, in either case to the effect that holders of the notes will not recognize income, gain or loss for federal income tax purposes as a result of the defeasance and discharge and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if the defeasance and discharge were not to occur.

In certain other circumstances, we may be able to cease complying with certain restrictive covenants, including those described under "Covenants—Restrictions on Secured Indebtedness," "Covenants—Limitation on Sale and Leasebacks," "Merger and Sales of Assets by IGT." In addition, in those circumstances, the occurrence of certain events of default will no longer be deemed not to be or result in an event of default with respect to the notes. In order to exercise this option, we will be required to deposit, in trust for the benefit of the holders of the notes, money or government obligations, or both, which, through the payment of principal of and interest on the deposited money or government obligations, will provide enough money to pay the principal of and any premium and interest on the notes on the stated maturities in accordance with the terms of the indenture and the notes. We will also be required, among other things, to deliver to the trustee an opinion of counsel to the effect that holders of the notes will not recognize income, gain or loss for federal income tax purposes as a result of the deposit and defeasance and will be subject to federal income tax on the same amount, in the same manner and at the same times as would have been the case if the deposit and defeasance were not to occur. If we exercise this option with respect to any notes and those notes are accelerated because of the occurrence of any event of default, the amount of money and U.S. government obligations deposited in trust will be sufficient to pay amounts due on those notes at the time of their stated maturities, but might not be sufficient to pay amounts due on those notes upon that acceleration. In that case, we will remain liable for the payments.

The indenture and the notes will be governed by, and construed in accordance with, the laws of the State of New York.

Wells Fargo Bank, National Association, is the trustee, registrar and paying agent.

If an event of default occurs and is continuing, the trustee will be required to use the degree of care and skill of a prudent person in the conduct of his own affairs. The trustee will become obligated to exercise any of its powers under the indenture at the request of any of the holders of any notes only after those holders have offered the trustee indemnity reasonably satisfactory to it.

If the trustee becomes one of our creditors, it will be subject to limitations in the indenture on its rights to obtain payment of claims or to realize on some property received for any such claim, as security or otherwise. The trustee is permitted to engage in other transactions with us. If, however, it acquires any conflicting interest, it must eliminate that conflict or resign.

We will issue the notes in registered form, without interest coupons. We will not charge a service charge for any registration of transfer or exchange of the notes. We may, however, require the payment of any tax or other governmental charge payable for that registration.

The notes will be exchangeable for other notes, for the same principal amount and for the same terms but in different authorized denominations in accordance with the indenture. Holders may present notes for registration of transfer at the office of the security registrar or any transfer agent we designate. The security registrar or transfer agent will effect the transfer or exchange when it is satisfied with the documents of title and identity of the person making the request. See "—Book-Entry System" below for further description of the procedures and requirements for transfer of ownership pursuant to DTC's book-entry transfer system.

We have appointed the trustee as security registrar for the notes. We may at any time rescind that designation or approve a change in the location through which any registrar acts. We are required to maintain an office or agency for transfers and exchanges in each place of payment. We may at any time designate additional registrars for the notes.

Except as otherwise described herein, notice to registered holders of the notes will be given by mail to the addresses as they appear in the security register. Notices will be deemed to have been given on the date of such mailing. If at any time we are required to give a notice pursuant to the terms of the indenture or the notes, we will also issue a press release containing the relevant information (and make that press release available on our website).

We will replace any notes that become mutilated, destroyed, stolen or lost at the expense of the holder upon delivery to the trustee of the mutilated notes or evidence of the loss, theft or destruction satisfactory to us and the trustee. In the case of a lost, stolen or destroyed notes, indemnity satisfactory to the trustee and us may be required at the expense of the holder of the notes before a replacement note will be issued.

The notes will be represented by one or more global securities (each a "global security"). Each global security will be deposited with, or on behalf of, DTC and be registered in the name of a nominee of DTC. Except under circumstances described below, the notes will not be issued in definitive form.

Upon the issuance of a global security, DTC will credit on its book-entry registration and transfer system the accounts of persons designated by the underwriters with the respective principal amounts of the notes represented by the global security. Ownership of beneficial interests in a global security will be limited to persons that have accounts with DTC or its nominee ("participants") or persons that may hold interests through participants. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of persons other than participants). The laws of some states require that some purchasers of securities take physical delivery of the securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in a global security.

Investors may hold interests in the global securities either through DTC (in the United States) or through Clearstream Banking, société anonyme, Luxembourg ("Clearstream"), or Euroclear Bank S.A./N.V., as operator of the Euroclear System ("Euroclear") (in Europe), either directly if they are participants in such systems or indirectly through organizations that are participants in such systems. Clearstream and Euroclear will hold interests on behalf of their participants through customers' securities accounts in their respective names on the books of their U.S. depositaries, which in turn will hold such interests in customers' securities accounts as participants of DTC.

So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes represented by that global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have the notes represented by that global security registered in their names, will not receive or be entitled to receive physical delivery of the notes in definitive form, and will not be considered the owners or holders thereof under the indenture. Principal and interest payments, if any, on the notes registered in the name of DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner of the relevant global security. Neither IGT, the trustee, any paying agent or the registrar for the notes will have any responsibility or liability for any aspect of the records relating to nor payments made on account of beneficial interests in a global security or for maintaining, supervising or reviewing any records relating to such beneficial interests.

We expect that DTC or its nominee, upon receipt of any payment of principal or interest, if any, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the relevant global security as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in a global security held through these participants will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of the participants. Distributions on the notes held beneficially through Clearstream and Euroclear will be credited to cash accounts of its customers in accordance with their respective rules and procedures, to the extent received by their respective U.S. depositaries.

If DTC is at any time unwilling or unable to continue as a depositary and a successor depositary is not appointed by us within 90 days, we will issue the notes in definitive form in exchange for the entire global security for the notes. In addition, we may at any time and in our sole discretion determine not to have the notes represented by a global security and, in such event, will issue the notes in definitive form in exchange for the entire global security relating to the notes. In any such instance, an owner of a beneficial interest in a global security will be entitled to physical delivery in definitive form of the notes represented by the global security equal in principal amount to the beneficial interest and to have the notes registered in its name. Notes so issued in definitive form will be issued as registered notes in minimum denominations of $2,000 and integral multiples of $1,000, unless otherwise specified by us.

Initial settlement for the notes will be made in immediately available funds. Secondary market trading between DTC participants will occur in the ordinary way in accordance with DTC rules. Secondary market trading between Clearstream customers and/or Euroclear participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and Euroclear, as applicable.

Cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream customers or Euroclear participants, on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by the U.S. depositary. Such cross-market transactions will, however, require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to the U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving the notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC.

Clearstream customers and Euroclear participants may not deliver instructions directly to their U.S. depositaries.

Because of time-zone differences, credits of the notes received in Clearstream or Euroclear as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in the notes settled during such processing will be reported to the relevant Clearstream customers or Euroclear participants on such business day. Cash received in Clearstream or Euroclear as a result of sales of the notes by or through a Clearstream customer or a Euroclear participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or Euroclear cash account only as of the business day following settlement in DTC.

Although DTC, Clearstream and Euroclear have agreed to the foregoing procedures to facilitate transfers of the notes among participants of DTC, Clearstream and Euroclear, they are under no obligation to perform or continue to perform such procedures and such procedures may be changed or discontinued at any time.

We understand that DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues, and money market instruments (from over 100 countries) that DTC's participants ("direct participants") deposit with DTC. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between direct participants' accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation ("DTCC"). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. DTC has Standard & Poor's highest rating: AAA. The DTC Rules applicable to its participants are on file with the Commission. More information about DTC can be found at www.dtcc.com and www.dtc.org.

We understand that Clearstream is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its customers and facilitates the clearance and settlement of securities transactions between its customers through electronic book-entry changes in accounts of its customers, thereby eliminating the need for physical movement of certificates. Clearstream provides to its customers, among other things, services for safekeeping, administration, clearance and settlement of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Commission for the Supervision of the Financial Section. Clearstream customers are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and other organizations and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers, dealers

and trust companies that clear through or maintain a custodial relationship with a Clearstream customer either directly or indirectly.

We understand that Euroclear was created in 1968 to hold securities for participants of Euroclear and to clear and settle transactions between Euroclear participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear provides various other services, including securities lending and borrowing and interfaces with domestic markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the "Euroclear Operator"), under contract with Euroclear Clearance Systems S.C., a Belgian cooperative corporation (the "Cooperative"). The Euroclear Operator conducts all operations, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear participants. Euroclear participants include banks (including central banks), securities brokers and dealers, and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear participant, either directly or indirectly. The Euroclear Operator is licensed by the Belgian Banking and Finance Commission to carry out banking activities on a global basis. As a Belgian bank, it is regulated and examined by the Belgian Banking and Finance Commission.

We have provided the descriptions of the operations and procedures of DTC, Clearstream and Euroclear in this prospectus supplement solely as a matter of convenience. These operations and procedures are solely within the control of those organizations and are subject to change by them from time to time. None of us, the underwriters or the trustee takes any responsibility for these operations or procedures, and you are urged to contact DTC, Clearstream and Euroclear or their participants directly to discuss these matters.

The following is a general discussion of certain U.S. federal income tax consequences relating to the purchase, ownership and disposition of the notes. The discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury regulations, judicial decisions, published positions of the Internal Revenue Service (the "IRS") and other applicable authorities, all as in effect as of the date hereof and all of which are subject to change or differing interpretations (possibly with retroactive effect). The discussion does not address all of the tax consequences that may be relevant to a particular person or to persons subject to special treatment under the U.S. federal income tax laws (such as financial institutions, broker-dealers, traders in securities that elect to use a mark-to-market method of accounting, insurance companies, regulated investment companies, real estate investment companies, expatriates, tax-exempt organizations, persons subject to the alternative minimum tax, persons that are, or hold their notes through, partnerships or other pass-through entities, or persons who have a functional currency other than the U.S. dollar) or to persons that hold their notes as part of a straddle, hedge, conversion, synthetic security or constructive sale transaction for U.S. federal income tax purposes, all of whom may be subject to tax rules that differ from those summarized below. Moreover, except as expressly provided below, the discussion does not address any tax consequences other than U.S. federal income tax consequences. This summary deals only with holders that hold the notes as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment) and only with notes that were issued by us on the issue date at the issue price. No IRS ruling has been or will be sought by us regarding any matter discussed herein. No assurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of those set forth below.

For purposes of this discussion, a "U.S. holder" means a beneficial owner (as determined for U.S. federal income tax purposes) of a note that is, or is treated as, one of the following:

A "non-U.S. holder" means any beneficial owner of a note (other than a partnership or any entity treated as a partnership for U.S. federal income tax purposes) that is not a "U.S. holder."

If an entity that is classified as a partnership for U.S. federal income tax purposes holds a note, the U.S. federal income tax treatment of a partner in such partnership will generally depend on the status of the partner and upon the activities of the partnership. Partnerships holding a note and partners in such partnership should consult their tax advisors as to the particular U.S. federal income tax consequences of holding and disposing of the notes.

The discussion below necessarily represents only a general summary. Moreover, the effects of any applicable state, local or foreign tax laws are not discussed. We urge investors considering the purchase of notes to consult their own tax advisor concerning the U.S. federal income tax consequences of owning and disposing of the notes, as well as any consequences to them under the laws of any state, local or foreign taxing jurisdiction.

We believe the notes will be treated as indebtedness for U.S. federal income tax purposes. This summary discussion assumes that the IRS will respect this classification.

It is not expected that the notes will be issued with more than a de minimis amount of original issue discount ("OID"). Accordingly, it is expected that U.S. holders of the notes will be required to recognize as ordinary income any interest paid or accrued on the notes in accordance with their regular method of tax accounting. If, however, the notes are issued with OID (defined generally as the excess of a note's "stated redemption price at maturity" over its issue price, if in excess of a de minimis amount), then the amount of OID on a note must be included in income as ordinary interest income as it accrues under a constant yield method in advance of receipt of the cash payments attributable to such income, regardless of such U.S. holders regular method of tax accounting. In addition, any amount not treated as OID because it is de minimis (i.e., less than 0.25% of a note's stated redemption price at maturity multiplied by the number of complete years from the issue date to maturity) must be included in income (generally as gain from the sale of such note) as principal payments are received on the notes in proportion to the amount that each such payment bears to the original principal amount of such note. The discussion below assumes that the notes have not been issued with more than a de minimis amount of OID.

We will be required to pay additional amounts to holders on the occurrence of certain events, including, among others, if we are required to repurchase the notes in connection with a change of control repurchase event (as described under "Description of Notes—Change of Control Repurchase Event") and if we are required to pay additional interest in certain events of default (as described under "Description of Notes—Events of Default). We believe the likelihood that we will be obligated to make any such additional payments on the notes is remote, and, although the matter is not entirely free from doubt, we therefore do not believe that these possible additional amounts will cause the notes to be treated as contingent payment debt instruments. Assuming our position is respected, U.S. holders would be required to treat any additional interest as ordinary interest income and include such amounts in income at the time payments are received or accrued, in accordance with their regular method of tax accounting for U.S. federal income tax purposes. Assuming our position is respected, U.S. holders would be required to treat any repurchase of the notes as described in "Sale, Exchange, Redemption or Retirement of Notes" below. Our determination that the notes are not contingent payment debt instruments is not, however, binding on the IRS. If the IRS were to challenge our determination successfully and the notes were treated as contingent payment debt instruments, a U.S. holder may be required, among other things, to accrue interest income (regardless of their regular method of tax accounting for U.S. federal income tax purposes) at a rate higher than the stated interest rate on the notes. In addition, on a sale, exchange or redemption of a note, U.S. holders would generally be required to treat any gain as ordinary income rather than capital gain. Our determination that the notes are not contingent payment debt instruments is binding on U.S. holders unless they disclose their contrary positions to the IRS in the manner required by applicable Treasury regulations.

The remainder of this discussion assumes that the notes are not treated as contingent payment debt instruments. U.S. holders should consult their own tax advisors about the treatment of additional payments that might be made in respect of the notes.

Upon the sale, exchange, redemption or retirement of notes, a U.S. holder generally will recognize gain or loss equal to the difference between the amount realized on the sale, exchange, redemption or retirement (not including any amount attributable to accrued but unpaid interest, which is taxable as described in "U.S. Holders—Interest on Notes" above to the extent not previously included in income) and the U.S. holder's tax basis in the notes. A U.S. holder's tax basis in a note generally will be equal to the amount paid for the note.

Gain or loss so recognized will be capital gain or loss and will be long-term capital gain or loss, if, at the time of the sale, exchange, redemption or retirement, the notes were held for more than one year. Under current law, long-term capital gains of non-corporate taxpayers are, under certain circumstances, taxed at lower rates than items of ordinary income. The deductibility of capital losses is subject to limitations.

Subject to the discussion of backup withholding below, payments of interest by us or our agent (in its capacity as such) to any non-U.S. holder will generally not be subject to U.S. federal withholding tax, provided that:

If a non-U.S. holder cannot satisfy the requirements of the "portfolio interest" exemption described above, payments of interest made to such non-U.S. holder generally will be subject to a 30% withholding tax (or such lower rate as may be provided by an applicable income tax treaty between the United States and a foreign country) unless another exemption applies and such non-U.S. holder complies with the relevant certification requirements. Any prospective investor who may not satisfy the portfolio interest exemption requirements described above should consult its tax advisors prior to making an investment in the notes.

If a non-U.S. holder is engaged in a trade or business in the United States and interest on the notes is effectively connected with the conduct of such trade or business in the United States and, if required by an applicable income tax treaty as a condition to taxation, is attributable to a U.S. permanent establishment, such non-U.S. holder, although exempt from U.S. federal withholding tax (by reason of the delivery of a properly completed IRS Form W-8ECI or successor form), will be subject to U.S. federal income tax on such interest in the same manner as if it were a U.S. person. In addition, if such non-U.S. holder is a foreign corporation, it may be subject to an additional branch profits tax

equal to 30% (or lesser rate under an applicable income tax treaty) of its effectively connected earnings and profits, as defined in the Code, for the taxable year, subject to adjustments.

As described above under "—U.S. Holders—Additional Payments," we will be required to pay additional amounts to holders on the occurrence of certain events, including, among others, if we are required to repurchase the notes in connection with a change of control repurchase event or if we are required to pay additional interest in the event of certain events of default. It is possible that some or all of such payments might be subject to U.S. federal withholding tax as described above under "—Interest on Notes." However, if we were required to repurchase the notes in connection with a change of control repurchase event, such repurchase will be treated as described in "—Sale Exchange, Redemption or Retirement of Notes" below. Each non-U.S. holder that is considering the purchase of notes should consult its own tax advisor regarding the tax consequences that relate to the potential payment of additional interest or other contingencies.

Subject to the discussion of backup withholding below, any gain realized by a non-U.S. holder upon the sale, exchange, redemption or retirement of notes will not be subject to U.S. federal income or withholding taxes unless: (i) such gain is effectively connected with a U.S. trade or business of the non-U.S. holder (and, if required by an applicable income tax treaty as a condition to taxation, is attributable to a U.S. permanent establishment), in which case the non-U.S. holder will be subject to U.S. federal income tax on such gain as if it were a U.S. person; (ii) in the case of an individual, such non-U.S. holder is present in the United States for 183 days or more in the taxable year of the sale, exchange, redemption or retirement and certain other conditions are met; or (iii) such gain represents accrued interest, in which case the rules for interest would apply, as described in "Non-U.S. Holders—Interest on Notes" above. If a non-U.S. holder is a foreign corporation, gains effectively connected with a U.S. trade or business of such non-U.S. holder may be subject to an additional branch profits tax equal to 30% (or lesser rate under an applicable income tax treaty) of its effectively connected earnings and profits, as defined in the Code, for the taxable year, subject to adjustments.

Backup withholding and information reporting requirements may apply to certain payments of principal and interest on notes. We, our paying agent or certain other parties, as the case may be, will be required to withhold from any payment that is subject to backup withholding at a current rate of 28% of such payment if the holder fails to furnish the holder's taxpayer identification number (social security number or employer identification number), to certify that such holder is not subject to backup withholding, or to otherwise comply with the applicable requirements of the backup withholding rules. Certain holders (including, among others, corporations) are not subject to the backup withholding and information reporting requirements.

Backup withholding and information reporting generally will not apply to payments made by us or our agent (in its capacity as such) to a holder of notes who has provided the required certification under penalties of perjury that such holder is not a U.S. person as set forth in clause (5) under "Non-U.S. Holders—Interest on Notes" or has otherwise established an exemption (provided that neither we nor such agent has actual knowledge or reason to know that the holder is a U.S. person or that the conditions of any other exemption are not in fact satisfied). However, we and other payors may be required to report payments of interest on your notes on IRS Form 1042-S even if the payments are not otherwise subject to information reporting requirements.

Payments of the proceeds from the sale, exchange, redemption or retirement of a note to or through a foreign office of a broker will generally not be subject to information reporting or backup withholding. However, information reporting, but not backup withholding, may apply to those payments if the broker is one of the following:

Information reporting and backup withholding may apply to payments of the proceeds from a sale, exchange, redemption or retirement of a note held by a non-U.S. holder to or through the U.S. office of a broker unless the non-U.S. holder establishes an exemption from one or both.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules from a payment to a holder may be claimed as a credit against such holder's U.S. federal income tax liability and, if withholding results in an overpayment of tax, the holder may be entitled to a refund, provided the required information is timely furnished to the IRS and other applicable requirements are met. Holders should consult their own tax advisors regarding all aspects of the backup withholding rules, including the filing of a U.S. tax return and the claiming of a credit or refund of such backup withholding taxes.

The Foreign Account Tax Compliance Act provisions of the Hiring Incentives to Restore Employment Act (generally referred to as "FATCA"), when applicable, will impose a U.S. federal withholding tax of 30% on certain payments to "foreign financial institutions" and certain other non-financial foreign entities that fail to comply with certain certification and information reporting requirements. Under recently issued IRS guidance, these rules generally apply to payments in respect of certain securities (such as the debt securities) paid on or after July 1, 2014, and to gross proceeds from the sale or other disposition of certain securities (such as the debt securities) paid on or after January 1, 2017. FATCA withholding requirements do not apply to debt instruments issued before July 1, 2014, unless such debt instruments are significantly modified on or after that date. Accordingly, debt securities issued or significantly modified on or after July 1, 2014 will be subject to this regime. You should consult your tax adviser regarding the possible implications of FATCA for your investment in the debt securities.

As a result of legislative changes effective for tax years beginning after December 31, 2012, a 3.8% tax will be imposed on the net investment income (which, among other items, generally would include interest and gross proceeds from a disposition of notes) of certain individuals, trusts and estates that are U.S. Holders. You should consult your tax adviser regarding the potential application of this tax.

We and the underwriters for the offering named below have entered into an underwriting agreement with respect to the notes. Subject to certain conditions, each underwriter has severally agreed to purchase the principal amount of notes indicated in the following table.

The underwriters are committed to take and pay for all of the notes being offered, if any are taken.

Notes sold by the underwriters to the public will initially be offered at the initial public offering price set forth on the cover of this prospectus supplement. Any notes sold by the underwriters to securities dealers may be sold at a discount from the initial public offering price of up to % of the principal amount of notes. Any such securities dealers may resell any notes purchased from the underwriters to certain other brokers or dealers at a discount from the initial public offering price of up to % of the principal amount of notes. If all the notes are not sold at the initial offering price, the underwriters may change the offering price and the other selling terms. The offering of the notes by the underwriters is subject to receipt and acceptance and subject to the underwriters' right to reject any order in whole or in part.

The notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the notes on any securities exchange or for inclusion of the notes in any automated quotation system. We have been advised by the underwriters that the underwriters intend to make a market in the notes but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes.

In connection with the offering, the underwriters may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress.

The underwriters also may impose a penalty bid. This occurs when a particular underwriter repays to the underwriters a portion of the underwriting discount received by it because the representatives have repurchased notes sold by or for the account of such underwriter in stabilizing or short covering transactions.

These activities by the underwriters, as well as other purchases by the underwriters for their own accounts, may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the underwriters at any time. These transactions may be effected in the over-the-counter market or otherwise.

We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $ .

We have agreed to indemnify the underwriters against, or contribute to payments that the underwriters may be required to make in respect of, certain liabilities, including liabilities under the Securities Act of 1933, as amended.

Certain of the underwriters or their respective affiliates own our 3.25% convertible notes due 2014 and, as a result, may receive some of the proceeds of this offering to the extent we use such proceeds to redeem a portion of our 3.25% convertible notes due 2014. Because the underwriters or their affiliates or associated persons may receive more than 5% of the proceeds of this offering, this offering is made in compliance with the applicable provisions of Rule 5110 of the Financial Industry Regulatory Authority (FINRA) and NASD Conduct Rule 2720. Because the notes are investment-grade rated by one or more nationally recognized statistical rating agencies, a qualified independent underwriter is not required to be appointed; however, this offering will be conducted in accordance with all other applicable provisions of the FINRA rules.

The underwriters and their respective affiliates are full service financial institutions engaged in various activities, which may include sales and trading, commercial and investment banking, advisory, investment management, investment research, principal investment, hedging, market making, brokerage and other financial and non-financial activities and services. Certain of the underwriters and their respective affiliates have provided, and may in the future provide, a variety of these services to the issuer and to persons and entities with relationships with the issuer, for which they received or will receive customary fees and expenses. Each of the underwriters or their respective affiliates are lenders or have committed to lend to us under our senior credit facility. In addition, in the ordinary course of their various business activities, the underwriters and their respective affiliates, officers, directors and employees may purchase, sell or hold a broad array of investments and actively trade securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments for their own account and for the accounts of their customers, and such investment and trading activities may involve or relate to assets, securities and/or instruments of the issuer (directly, as collateral securing other obligations or otherwise) and/or persons and entities with relationships with the issuer. The underwriters and their respective affiliates may also communicate independent investment recommendations, market color or trading ideas and/or publish or express independent research views in respect of such assets, securities or instruments and may at any time hold, or recommend to clients that they should acquire, long and/or short positions in such assets, securities and instruments.

No action has been taken in any jurisdiction that would permit a public offering of the notes, or the possession, circulation or distribution of this prospectus supplement, accompanying prospectus or any other material relating to us or the notes in any jurisdiction where action for that purpose is required. Accordingly, the notes may not be offered or sold, directly or indirectly, and none of this prospectus supplement, the accompanying prospectus or any other offering material or advertisements in connection with the notes may be distributed or published, in or from any country or jurisdiction except in compliance with any applicable rules and regulations of any such country or jurisdiction.

The offering of the notes has not been registered pursuant to the Italian securities legislation and, accordingly, the underwriters have not offered or sold, and will not offer or sell, any notes in the Republic of Italy in a solicitation to the public, and sales of the notes in the Republic of Italy shall be effected in accordance with all Italian securities, tax and exchange control and other applicable laws and regulations. In any case, the notes cannot be offered or sold to any individuals in the Republic of Italy either in the primary market or the secondary market. The underwriters will not offer, sell or deliver any notes or distribute copies of this prospectus supplement, the accompanying prospectus or any other document relating to the notes in the Republic of Italy except: to "Professional Investors", as defined in Article 31.2 of the Italian Securities and Exchange Commission (CONSOB) Regulation No. 11522 of 2 July 1998 as amended ("Regulation No. 11522"), pursuant to Article 30.2 and 100 of Legislative Decree No. 58 of 24 February 1998 as amended ("Decree No. 58"), or in any other circumstances where an expressed exemption to comply with the solicitation restrictions provided by Decree No. 58 or Regulation No. 11971 of 14 May 1999 as amended applies, provided, however, that any such offer, sale or delivery of the notes or distribution of copies of the prospectus supplement, the accompanying prospectus or any other document relating to the notes in the Republic of Italy must be (a) made by investment firms, banks or financial intermediaries permitted to conduct such activities in the Republic of Italy in accordance with Legislative Decree No. 385 of 1 September 1993 as amended ("Decree No. 385"), Decree No. 58, CONSOB Regulation No. 11522 and any other applicable laws and regulations; (b) in compliance with Article 129 of Decree No. 385 and the implementing instructions of the Bank of Italy, pursuant to which the issue, trading or placement of securities in Italy is subject to a prior notification to the Bank of Italy, unless and exemption, depending, inter alia, on the aggregate amount and the characteristics of the notes issued or offered in the Republic of Italy,

applies; and (c) in compliance with any other applicable notification requirement or limitation which may be imposed by CONSOB or the Bank of Italy.

The notes may not be offered or sold by means of any document other than (i) in circumstances which do not constitute an offer to the public within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), or (ii) to "professional investors" within the meaning of the Securities and Futures Ordinance (Cap.571, Laws of Hong Kong) and any rules made thereunder, or (iii) in other circumstances which do not result in the document being a "prospectus" within the meaning of the Companies Ordinance (Cap.32, Laws of Hong Kong), and no advertisement, invitation or document relating to the notes may be issued or may be in the possession of any person for the purpose of issue (in each case whether in Hong Kong or elsewhere), which is directed at, or the contents of which are likely to be accessed or read by, the public in Hong Kong (except if permitted to do so under the laws of Hong Kong) other than with respect to notes which are or are intended to be disposed of only to persons outside Hong Kong or only to "professional investors" within the meaning of the Securities and Futures Ordinance (Cap.571, Laws of Hong Kong) and any rules made thereunder.

This prospectus supplement and the accompanying prospectus have not been registered as a prospectus with the Monetary Authority of Singapore. Accordingly, this prospectus supplement and the accompanying prospectus and any other document or material in connection with the offer or sale, or invitation for subscription or purchase, of the notes may not be circulated or distributed, nor may the notes be offered or sold, or be made the subject of an invitation for subscription or purchase, whether directly or indirectly, to persons in Singapore other than (i) to an institutional investor under Section 274 of the Securities and Futures Act, Chapter 289 of Singapore (the "SFA"), (ii) to a relevant person, or any person pursuant to Section 275(1A), and in accordance with the conditions, specified in Section 275 of the SFA or (iii) otherwise pursuant to, and in accordance with the conditions of, any other applicable provision of the SFA.

Where the notes are subscribed or purchased under Section 275 by a relevant person which is: (a) a corporation (which is not an accredited investor) the sole business of which is to hold investments and the entire share capital of which is owned by one or more individuals, each of whom is an accredited investor; or (b) a trust (where the trustee is not an accredited investor) whose sole purpose is to hold investments and each beneficiary is an accredited investor, shares, debentures and units of shares and debentures of that corporation or the beneficiaries' rights and interest in that trust shall not be transferable for 6 months after that corporation or that trust has acquired the notes under Section 275 except: (1) to an institutional investor under Section 274 of the SFA or to a relevant person, or any person pursuant to Section 275(1A), and in accordance with the conditions, specified in Section 275 of the SFA; (2) where no consideration is given for the transfer; or (3) by operation of law.

We expect that delivery of the notes will be made against payment therefor on or about , 2013, which will be the fifth business day following the date hereof (this settlement cycle being referred to as "T+5"). Pursuant to Rule 15c6-1 under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to the trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement and should consult their own advisor.

In this prospectus supplement and the accompanying prospectus, we "incorporate by reference" certain information we file with the SEC, which means that we can disclose important information to you by referring to that information. The information incorporated by reference is considered to be a part of this prospectus supplement and the accompanying prospectus, and later information filed with the SEC will update and supersede this information. We incorporate by reference the documents listed below and any future filings made with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act after the date of this prospectus supplement and until this offering is completed:

You may request a copy of these filings at no cost, by writing or telephoning us at:

You should rely only upon the information provided in this document or incorporated in this document by reference. We have not, and the underwriters have not, authorized anyone to provide you with different information. You should not assume that the information in this document, including any information incorporated by reference, is accurate as of any date other than the date indicated on the front cover.

Certain legal matters with respect to the notes will be passed upon for us by J. Kenneth Creighton, Esq., Vice President, Deputy General Counsel of IGT, and by O'Melveny & Myers LLP, San Francisco, California. Certain legal matters will be passed upon for the underwriters by Skadden, Arps, Slate, Meagher & Flom LLP, New York, New York.

The financial statements and management's assessment of the effectiveness of internal control over financial reporting (which is included in Management's Report on Internal Control over Financial Reporting) incorporated in this prospectus supplement and the accompanying prospectus by reference to the Annual Report on Form 10-K for the year ended September 30, 2012, have been so incorporated in reliance on the report, which contains an explanatory paragraph on the effectiveness of internal control over financial reporting due to the exclusion of certain elements of the internal control over financial reporting of the Double Down Interactive business the registrant acquired during 2012, of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

We may offer from time to time, in one or more series, debt securities. Our common stock is listed on the New York Stock Exchange and trades under the ticker symbol "IGT."

We may offer these securities in amounts, at prices and on terms determined at the time of offering. The specific plan of distribution for any debt securities to be offered will be provided in a prospectus supplement. If we use agents, underwriters or dealers to sell these securities, a prospectus supplement will name them and describe their compensation.

The specific terms of any debt securities to be offered will be described in a supplement to this prospectus. The prospectus supplement may also add, update or change information contained in this prospectus. You should read this prospectus and any prospectus supplement, together with additional information described under the heading "Where You Can Find More Information," before you make an investment decision.

Investing in our securities involves a high degree of risk. See "Risk Factors" beginning on page 2 of this prospectus.

Neither the Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

This prospectus is part of an "automatic shelf" registration statement that we filed with the United States Securities and Exchange Commission, or the SEC, as a "well-known seasoned issuer" as defined in Rule 405 under the Securities Act of 1933, as amended, or the Securities Act, using a "shelf" registration process. By using a shelf registration statement, we may sell debt securities from time to time and in one or more offerings. Each time we sell debt securities, we will provide a supplement to this prospectus that contains specific information about the debt securities being offered and the specific terms of that offering. The supplement may also add, update or change information contained in this prospectus. If there is any inconsistency between the information in this prospectus and any prospectus supplement, you should rely on the prospectus supplement. Before purchasing any debt securities, you should carefully read both this prospectus and any prospectus supplement, together with the additional information described under the heading "Where You Can Find More Information" and "Incorporation of Certain Documents by Reference."

We may also prepare free writing prospectuses to describe the terms of particular debt securities, which terms may vary from those described in this prospectus. Any free writing prospectus should therefore be carefully reviewed in connection with this prospectus and with any prospectus supplement referred to therein. A free writing prospectus will not constitute a part of this prospectus.

We have not authorized any dealer, salesman or other person to provide you with any information or to make any representation other than those contained or incorporated by reference in this prospectus and any accompanying prospectus supplement. You must not rely upon any information or representation not contained or incorporated by reference in this prospectus or in any accompanying prospectus supplement. This prospectus and any accompanying prospectus supplement do not constitute an offer to sell or the solicitation of an offer to buy any securities other than the securities to which they relate, nor do this prospectus and any accompanying prospectus supplement constitute an offer to sell or the solicitation of an offer to buy securities in any jurisdiction to any person to whom it is unlawful to make such an offer or solicitation in such jurisdiction. You should not assume that the information contained in this prospectus and the accompanying prospectus supplement is accurate on any date subsequent to the date set forth on the front of the document or that any information we have incorporated by reference is correct on any date subsequent to the date of the document incorporated by reference, even though this prospectus and any accompanying prospectus supplement is delivered or securities are sold on a later date. Our business, financial condition, results of operations and prospects may have changed since the dates first set forth on the front of the document or supplement thereto.

Unless otherwise stated, or the context otherwise requires, references in this prospectus to the "Company," "we," "us" and "our" refer to International Game Technology, those entities owned or controlled by International Game Technology and predecessors of International Game Technology.

Our fiscal year is reported on a 52/53-week period that ends on the Saturday nearest to September 30. For simplicity, this prospectus presents all fiscal years using the calendar month end as outlined in the table below.

An investment in our securities involves a high degree of risk. You should carefully consider the risk factors contained in our most recent Annual Report on Form 10-K and other subsequent filings with the SEC pursuant to Sections 13(a), 13(c), 14 or 15(d) of the Exchange Act, each of which is incorporated by reference, and those risk factors that may be included or incorporated by reference under the caption "Risk Factors" in any applicable prospectus supplement, together with all of the other information included in this prospectus, any prospectus supplement and the documents we incorporate by reference before making an investment decision.

We have filed our registration statement on Form S-3 with the SEC under the Securities Act. We also file annual, quarterly and current reports, proxy statements and other information with the SEC. You may read and copy any document that we file with the SEC, including the registration statement and the exhibits to the registration statement, at the SEC's Public Reference Room at:

You may call the SEC's Public Reference Room at 1-800-SEC-0330 for further information. Our SEC filings are also available to the public at the SEC's web site at www.sec.gov. In addition, you may inspect and copy reports, proxy statements and other information about us at the offices of the New York Stock Exchange, Inc. at 20 Broad Street, New York, New York 10005.

This prospectus and any prospectus supplement are part of a registration statement that we filed with the SEC and do not contain all of the information in the registration statement. The full registration statement may be obtained from the SEC as indicated above. Forms of the indenture and other documents establishing the terms of the offered debt securities are filed as exhibits to the registration statement or will be filed through an amendment to our registration statement on Form S-3 or under cover of a Current Report on Form 8-K and incorporated in this prospectus by reference. Statements in this prospectus or any prospectus supplement about these documents are summaries and each statement is qualified in all respects by reference to the document to which it refers. You should refer to the actual documents for a more complete description of the relevant matters.

The SEC allows us to "incorporate by reference" in this prospectus the information we file with it, which means that we can disclose important information to you by referring you to those documents. The information incorporated by reference is considered to be part of this prospectus, and later information filed with the SEC will update and supersede the information included or incorporated by reference in this prospectus. We incorporate by reference in this prospectus the following information:

We also incorporate by reference any future filings we may make with the SEC under Sections 13(a), 13(c), 14 or 15(d) of the Securities Exchange Act of 1934 prior to the termination of this offering, other than documents or information deemed furnished and not filed in accordance with SEC rules.

We are not, however, incorporating by reference any documents or portions thereof, whether specifically listed above or filed in the future, that are not deemed "filed" with the SEC, including any information furnished pursuant to Items 2.02 and 7.01 of Form 8-K or certain exhibits furnished pursuant to Item 9.01 of Form 8-K.

You may request a copy of these filings, at no cost, by writing or telephoning us at the following address:

These filings can also be obtained through the SEC as described above or, with respect to certain of these documents, at our website at www.igt.com. Except for the documents described above, information on our website is not incorporated by reference into this prospectus.

This prospectus contains or incorporates by reference, and any prospectus supplement will contain or incorporate by reference, statements that constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements relate to analyses and other information based on forecasts of future results and estimates of amounts not yet determinable. These statements may also relate to future events or trends, our future prospects and proposed new products, services, developments, or business strategies, among other things. These statements can generally (although not always) be identified by their use of terms and phrases such as "anticipate," "appear," "believe," "could," "would," "estimate," "expect," "indicate," "intend," "may," "plan," "predict," "project," "pursue," "will," "continue," and other similar terms and phrases, as well as the use of the future tense.

Examples of forward looking statements in or incorporated by reference in this prospectus include, but are not limited to, the following matters:

business and operating results, including those made in "Part I, Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended September 30, 2011 and in "Part II, Item 1A. Risk Factors" of our Quarterly Report on Form 10-Q for the quarter ended December 31, 2011 and as such risk factors may be updated in subsequent SEC filings, as well as our other reports filed with the SEC and in any prospectus supplement. You should not assume at any point in the future that the forward looking statements in this prospectus are still valid. We do not intend, and undertake no obligation, to update our forward looking statements to reflect future events or circumstances after the date of this prospectus or any prospectus supplement, unless required by law to do so.

The table below sets forth the ratio of earnings to fixed charges of the Company and its consolidated subsidiaries on a historical basis for each of the periods indicated:

For the purpose of computing this ratio, earnings represent income from continuing operations before fixed charges and income taxes, adjusted to exclude capitalized interest. Fixed charges represent interest expense excluding the portion related to liabilities to jackpot winners and including capitalized interest, one-third of total rental expense (which represents a reasonable approximation of the interest factor), and amortization of discount and loan expense related to long-term debt. All periods presented have been recast for discontinued operations.

We intend to use the net proceeds from the sale of the securities as set forth in the applicable prospectus supplement.

In connection with particular offerings of the securities in the future, and if stated in the applicable prospectus supplements, the validity of those securities may be passed upon for us by Sidley Austin LLP, and for any underwriters or agents by counsel named in the applicable prospectus supplement.

The consolidated financial statements as of September 30, 2011 and September 30, 2010 and for each of the two years in the period ended September 30, 2011 and management's assessment of the effectiveness of our internal control over financial reporting (which is included in Management's Report on Internal Control over Financial Reporting) as of September 30, 2011, incorporated in this prospectus by reference to the Annual Report on Form 10-K for the fiscal year ended September 30, 2011 have been so incorporated in reliance on the report (which contains an explanatory paragraph on the effectiveness of internal control over financial reporting due to the exclusion of the internal control over financial reporting of the Entraction Holding AB business acquired by the registrant in a purchase business combination during 2011) of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in accounting and auditing.

The consolidated financial statements for the fiscal year ended September 30, 2009 incorporated in this prospectus by reference to the Annual Report on Form 10-K for the fiscal year ended September 30, 2011, have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is incorporated herein by reference.

Such consolidated financial statements have been so incorporated in reliance upon the reports of said firms given upon their authority as experts in accounting and auditing.
