Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	*Basis of Presentation and Principles of Consolidation* The accompanying unaudited condensed consolidated financial statements include the accounts of High Roller Technologies, Inc., and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated upon consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared and presented in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and the instructions to From 10-Q and Article 8 of Regulation S-X and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”) for interim reporting. As permitted under those rules, certain footnotes and financial information that are normally required under U.S. GAAP can be condensed or omitted. The condensed consolidated balance sheet as of December 31, 2024, was derived from audited consolidated financial statements but does not include all disclosures required by U.S. GAAP. The information included in this interim report should be read in conjunction with the audited consolidated financial statements and notes thereto of the Company for the year ended December 31, 2024, as previously filed with the SEC. In the opinion of management, these unaudited condensed consolidated financial statements have been prepared on the same basis as the annual consolidated financial statements and notes thereto of the Company and include all adjustments, consisting only of normal recurring adjustments considered necessary for the fair presentation of the Company’s financial position and operating results. Operating results for the interim periods presented are not necessarily indicative of the results expected for a full fiscal year.
Going Concern [Policy Text Block]	*GOING CONCERN* The Company had a net working capital deficiency of $5.0 million, an accumulated deficit of $31.0 million and unrestricted cash resources of $2.7 million at June 30, 2025. During the year ended December 31, 2024, the Company incurred a net loss of $5.9 million. During the three months ended June 30, 2025 and 2024, the Company incurred a net loss of $592 thousand and $1.5 million, respectively. During the six months ended June 30, 2025 and 2024, the Company incurred a net loss of $3.9 million and $3.4 million, respectively. The Company’s unaudited condensed consolidated financial statements have been presented on the basis that it will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has financed its working capital requirements historically through the continuing financial support of affiliates and related parties. The Company’s ability to continue as a going concern is dependent upon its ability to obtain the necessary financing to meet its continuing obligations and repay its liabilities arising from normal business operations when they become due, to fund the development and expansion of its business activities, and to generate sustainable operating profits and cash flows in the future. As a result of these factors, at June 30, 2025, management had concluded that there was substantial doubt about the Company’s ability to continue as a going concern. The Company’s ability to continue as a going concern for 12 months from the date that these condensed consolidated financial statements are being issued is dependent upon its ability to generate sufficient cash flows from operations to meet its obligations, which it has not been able to accomplish to date, and to obtain additional capital financing as may be necessary, of which there can be no assurance that the Company will be successful in these efforts. The accompanying condensed consolidated financial statements do not include any adjustments that might result from this uncertainty. If cash resources are insufficient to satisfy the Company’s ongoing cash requirements, the Company would be required to scale back or discontinue its operations, or obtain funds, if available, through strategic alliances or joint ventures that could require the Company to relinquish rights to and/or control of gaming licenses and/or operations, or to discontinue operations entirely.
Risk and Uncertainties [Policy Text Block]	*Risk and Uncertainties* The Company’s business and operations are sensitive to general business and economic conditions worldwide. These conditions include short-term and long-term interest rates, inflation, fluctuations in debt and equity capital markets, cash transfer rules and restrictions, and the general condition of the world economy. A host of factors beyond the Company’s control could cause fluctuations in these conditions. Adverse developments in these general business and economic conditions could have a material adverse effect on the Company’s financial condition and the results of its operations. The Company’s business and operations are also sensitive to continually evolving online gaming regulatory and licensing requirements. In addition, the Company competes with many companies that currently have extensive and well-funded businesses, marketing and sales operations. The Company may be unable to compete successfully against these companies. The Company’s industry is characterized by rapid changes in technology and market demands. As a result, the Company’s products, services, or expertise may become obsolete or unmarketable. The Company’s future success will depend on its ability to adapt to technological advances, anticipate customer and market demands, and enhance its current technology under development.
Use of Estimates, Policy [Policy Text Block]	*Use of Estimates* The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions. Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable in relation to the financial statements taken as a whole under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Management regularly evaluates the key factors and assumptions used to develop the estimates utilizing currently available information, changes in facts and circumstances, historical experience and reasonable assumptions. After such evaluations, if deemed appropriate, those estimates are adjusted accordingly. Actual results could differ from those estimates. Significant estimates include those related to assumptions used in accruals for potential legal and other liabilities, realization of intangible assets, share-based compensation, accrued jackpots, the realization of deferred tax assets, and going concern assessment.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	*INTANGIBLE ASSETS, NET* Intangible assets with finite useful lives that are acquired are carried at cost less accumulated amortization and accumulated impairment losses. Amortization expense is recognized on a straight-line basis over the estimated useful lives of the intangible assets. The estimated useful lives and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimates being accounted for on a prospective basis.
Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]	IMPAIRMENT OF LONG-LIVED ASSETS The Company’s long-lived assets consist of property and equipment, operating lease-right of use assets and indefinite lived assets (i.e. trademarks and domain name). The Company evaluates long-lived assets for indicators of impairment at least annually or when events or changes in circumstances indicate that their carrying amounts may not be recoverable. The factors that would be considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the long-lived asset is used and the effects of obsolescence, demand, competition and other economic factors. If indicators of impairment are identified, the Company performs an undiscounted cash flow analysis of the long-lived assets. Asset groups are written down only to the extent that their carrying value is lower than their respective fair value. Fair values of the asset group are determined by discounting the cash flows at a rate that approximates the cost of capital of a market participant. Indefinite-lived intangible assets consist of trademarks and domain name. Indefinite-lived intangible assets are not amortized; rather they are tested for impairment at least annually, or more frequently if adverse events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, management evaluates whether events and circumstances continue to support an indefinite useful life. Impairment tests are performed, at a minimum, in the fourth quarter of each year. To test indefinite-lived intangible assets for impairment, the Company first assesses the qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative impairment test. If the Company determines that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, then the quantitative impairment test is performed. The qualitative assessment requires the consideration of factors such as recent market transactions, macroeconomic conditions, and changes in projected future cash flows. The quantitative assessment compares the fair value of an indefinite-lived intangible asset to its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized for the excess. Fair values of indefinite-lived intangible assets are determined based on discounted cash flows. The Company conducted an impairment analysis with respect to the casino room trademarks and HighRoller domain names at June 30, 2025, which concluded that the fair value, determined using a discounted cash flow analysis, substantially exceed their carrying value, and thus they were not impaired. Projected cash flows included an estimated commission fee for referring a player who opens an account with a deposit to an online gaming site, as well as future revenue sharing agreements for those customers based upon net gaming revenue over an estimated gaming period ranging from approximately 5 months to 12 months. The Company did not have any impairment of indefinite-lived intangible assets during the six months ended June 30, 2025 and 2024.
Cash and Cash Equivalents, Policy [Policy Text Block]	*Cash and Cash Equivalents, and Restricted Cash* Cash and cash equivalents consist of liquid checking and instant access internet banking accounts with original maturities of ninety days or less, as well as cash balances held with payment service providers, that are subject to an insignificant risk of change in value. Cash and cash equivalents that are legally restricted as to withdrawal or usage are classified as current or non-current restricted cash, as applicable, in the consolidated balance sheets. Entertainment, HR Entertainment and Interstellar Entertainment N.V. maintain separate accounts with various intermediary parties to segregate cash that resides in customers’ interactive gaming accounts from cash used in operating activities. Player funds denoted as such by Entertainment at the end of each period are classified as restricted cash. Player funds include cash amounts that reside in players’ interactive gaming withdrawals that were initiated by players but that are still pending at the end of each period, and the value of any bets that are unsettled at the end of each period.
Accounts Receivable, Related Party Transactions Policy [Policy Text Block]	DUE FROM AFFILIATES Due from affiliates consists of amounts expected to be collected from certain affiliated companies under common control. Amounts due reflect the revenues recorded by the Company under intra-group services arrangements for maintenance and operations of the iCasino platform on behalf of Interactive. As of June 30, 2025 and December 31, 2024, due from affiliates primarily reflected amounts due from Spike Up and Happy Hour Entertainment Holdings (see Note 12). On a periodic basis, the Company evaluates the collectability of amounts due from affiliates and establishes an allowance for amounts not expected to be collected. No allowance was recorded for the periods presented in the consolidated financial statements.
Accounts Payable, Related Party Transactions Policy [Policy Text Block]	*Due to AFFILIATES* Due to affiliates consists of amounts owed by the Company to certain of its related parties and affiliates. Amounts due to affiliates may include payment for services provided to the Company by employees of the related party or affiliate, or reimbursement of amounts paid by the related party or affiliate on the Company’s behalf.
Lessee, Leases [Policy Text Block]	Leases The Company accounts for leases in accordance with ASC 842, Leases, under which arrangements meeting the definition of a lease are classified as operating or finance leases and are recorded on the consolidated balance sheets as both a right-of-use asset and a lease liability. The Company elected to apply the practical expedient that allows for the combination of lease and non-lease components for all asset classes. The lease classification evaluation begins at the lease commencement date. The lease term used in the evaluation includes the non-cancellable period for which the Company has the right to use the underlying asset, together with renewal option periods when the exercise of the renewal option is reasonably certain. For leases with an initial term greater than 12 months, a related lease liability is recorded on the balance sheet at the present value of future payments discounted at the estimated fully collateralized incremental borrowing rate (discount rate) corresponding with the lease term. In addition, a right-of-use asset is recorded as the initial amount of the lease liability, plus any lease payments made to the lessor before or at the lease commencement date and any initial direct costs incurred, less any tenant improvement allowance incentives received. Tenant incentives are amortized through the right-of-use asset as a reduction of rent expense over the lease term. The difference between the minimum rents paid and the straight-line rent is reflected within the associated right-of-use asset. Certain leases contain provisions that require variable payments consisting of common area maintenance costs (variable lease cost).Variable lease costs are expensed as incurred. As the interest rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate corresponding with the lease term. As the Company does not have any outstanding debt, this rate is determined based on prevailing market conditions and comparable company and credit analysis. The incremental borrowing rate is reassessed if there is a change to the lease term or if a modification occurs and it is not accounted for as a separate contract.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	*Foreign Currency and Foreign Exchange Risk* The condensed consolidated financial statements are presented in United States Dollars ($), which is the Company’s reporting currency. Foreign currency exchange risk is the risk that the Company’s results of operations and/or financial condition could be impacted by unfavorable changes in exchange rates. The Company has transactions denominated in currencies other than the U.S. Dollar, principally the Euro but also other foreign currencies including Norwegian Krone, New Zealand Dollar and Canadian Dollar, that expose the Company’s operations to risk from the effects of exchange rate movements. Such movements may impact future revenues, expenses, and cash flows. Translation adjustments resulting from the process of translating the local currency financial statements into U.S. dollars are included in determining other comprehensive income. Changes in the value of the Company’s cash balance due to fluctuations in foreign exchange rate are presented in the unaudited condensed consolidated statements of cash flows as effect of foreign exchange rate changes on cash, cash equivalents, and restricted cash. As of June 30, 2025 and December 31, 2024, 83% and 33%, respectively, of the Company’s cash, cash equivalents and restricted cash reside in bank accounts located outside of the United States. The Company’s primary foreign currency exchange risk occurs between the time when other foreign currencies are exchanged for wagering on the Platform, and when those funds are settled to the Company in Euro. The relatively stable status of the Euro reduces but does not eliminate the Company’s exposure to foreign currency exchange risk. In addition, gains and losses related to translating certain cash balances from the Euro to the U.S. Dollar, as well as payable balances also impact net income. As the Company’s foreign operations expand, results may be impacted further by fluctuations in the exchange rates of the currencies in which the Company does business. The Company has not used any derivative financial instruments to manage its foreign currency exchange risk exposure. In most of the Company’s operations, the Company transacts primarily in the Euro, including wagered amounts, net revenue, revenue share, and employee-related compensation costs. Operating arrangements with payment service providers who convert player funds to the Euro from other currencies, for example the Canadian Dollar, could further negatively impact foreign currency exchange risk if the exchange spot rates used are unfavorable as compared to European Central Bank exchange rates. Foreign currency gains and losses arising from transactions denominated in currencies other than the functional currency are included in net loss and are included within general and administrative expenses. For the six months ended June 30, 2025 and 2024, the Company incurred foreign currency transaction losses of $329 thousand and $715 thousand, respectively. For the three months ended June 30, 2025 and 2024, the Company incurred foreign currency transaction losses of $151 thousand and $250 thousand, respectively. While the Company expects these losses to persist through 2025, it continues to manage and negotiate contracts with payment providers. The effects of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive loss in the accompanying condensed consolidated balance sheets. Foreign currency fluctuations between the functional and reporting currency can significantly impact the currency translation adjustment component of accumulated other comprehensive income.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	*Credit Risk* The Company’s credit risk arises from cash and cash equivalents, and restricted cash and deposits with banks and other financial institutions. The Company maintains balances in banks in the United States and outside of the United States, primarily within the European Union. For funds held within the United States, the Federal Deposit Insurance Corporation insures $250 thousand per depositor per FDIC insured bank. For funds held within the European Union, the European Deposit Insurance Scheme insures €100 thousand per depositor per bank. The Company has funds in Finland, Cyprus, Lithuania, and Malta that are protected under this scheme. The Company mitigates potential cash risk by diversifying bank accounts with insured banking institutions within the United States and European Union. Furthermore, the Company maintains cash in payment service provider accounts and other such financial institutions that may or may not be protected under the previously mentioned insurance schemes. The Company mitigates this potential risk by drawing down funds and transferring them to insured bank accounts on a regular basis. Any loss incurred or lack of access to such funds could have an adverse impact on the Company’s financial conditions, results of operations and cash flows period.
New Accounting Pronouncements, Policy [Policy Text Block]	*RecentLY ADOPTED Accounting Pronouncements* In December 2023, the FASB issued ASU 2023- 09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures (“ASU 2023- 09”). The amendments in ASU 2023- 09 are intended to increase transparency through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. ASU 2023- 09 is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023- 09 on January 1, 2025. The new disclosures will be reflected in the Company's annual consolidated financial statements for the year ended December 31, 2025. The adoption of ASU 2023- 09 was not material to the Company. *RecentLY ANNOUNCED Accounting Pronouncements* In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses. This guidance requires additional disclosure of certain amounts included in the expense captions presented on the Statement of Operations as well as disclosures about selling expenses. The ASU is effective on a prospective basis, with the option for retrospective application, for annual periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted for annual financial statements that have not yet been issued. The Company is currently evaluating the impact of this ASU on its consolidated financial statements and related disclosures. Management does not believe that any other recently issued, but not yet effective, authoritative guidance, if currently adopted, would have a material impact on the Company’s financial statement presentation or disclosures.

Going Concern [Policy Text Block]

GOING CONCERN

The Company had a net working capital deficiency of $5.0 million, an accumulated deficit of $31.0 million and unrestricted cash resources of $2.7 million at June 30, 2025. During the year ended December 31, 2024, the Company incurred a net loss of $5.9 million. During the three months ended June 30, 2025 and 2024, the Company incurred a net loss of $592 thousand and $1.5 million, respectively. During the six months ended June 30, 2025 and 2024, the Company incurred a net loss of $3.9 million and $3.4 million, respectively.

The Company’s unaudited condensed consolidated financial statements have been presented on the basis that it will continue as a going concern, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The Company has financed its working capital requirements historically through the continuing financial support of affiliates and related parties. The Company’s ability to continue as a going concern is dependent upon its ability to obtain the necessary financing to meet its continuing obligations and repay its liabilities arising from normal business operations when they become due, to fund the development and expansion of its business activities, and to generate sustainable operating profits and cash flows in the future.

As a result of these factors, at June 30, 2025, management had concluded that there was substantial doubt about the Company’s ability to continue as a going concern. The Company’s ability to continue as a going concern for 12 months from the date that these condensed consolidated financial statements are being issued is dependent upon its ability to generate sufficient cash flows from operations to meet its obligations, which it has not been able to accomplish to date, and to obtain additional capital financing as may be necessary, of which there can be no assurance that the Company will be successful in these efforts. The accompanying condensed consolidated financial statements do not include any adjustments that might result from this uncertainty.

If cash resources are insufficient to satisfy the Company’s ongoing cash requirements, the Company would be required to scale back or discontinue its operations, or obtain funds, if available, through strategic alliances or joint ventures that could require the Company to relinquish rights to and/or control of gaming licenses and/or operations, or to discontinue operations entirely.

Risk and Uncertainties [Policy Text Block]

Risk and Uncertainties

The Company’s business and operations are sensitive to general business and economic conditions worldwide. These conditions include short-term and long-term interest rates, inflation, fluctuations in debt and equity capital markets, cash transfer rules and restrictions, and the general condition of the world economy. A host of factors beyond the Company’s control could cause fluctuations in these conditions. Adverse developments in these general business and economic conditions could have a material adverse effect on the Company’s financial condition and the results of its operations.

The Company’s business and operations are also sensitive to continually evolving online gaming regulatory and licensing requirements. In addition, the Company competes with many companies that currently have extensive and well-funded businesses, marketing and sales operations. The Company may be unable to compete successfully against these companies. The Company’s industry is characterized by rapid changes in technology and market demands. As a result, the Company’s products, services, or expertise may become obsolete or unmarketable. The Company’s future success will depend on its ability to adapt to technological advances, anticipate customer and market demands, and enhance its current technology under development.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets, liabilities, revenue and expenses. Some of those judgments can be subjective and complex, and therefore, actual results could differ materially from those estimates under different assumptions or conditions. Management bases its estimates on historical experience and on various assumptions that are believed to be reasonable in relation to the financial statements taken as a whole under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Management regularly evaluates the key factors and assumptions used to develop the estimates utilizing currently available information, changes in facts and circumstances, historical experience and reasonable assumptions. After such evaluations, if deemed appropriate, those estimates are adjusted accordingly. Actual results could differ from those estimates. Significant estimates include those related to assumptions used in accruals for potential legal and other liabilities, realization of intangible assets, share-based compensation, accrued jackpots, the realization of deferred tax assets, and going concern assessment.

Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]

INTANGIBLE ASSETS, NET

Intangible assets with finite useful lives that are acquired are carried at cost less accumulated amortization and accumulated impairment losses. Amortization expense is recognized on a straight-line basis over the estimated useful lives of the intangible assets. The estimated useful lives and amortization method are reviewed at the end of each reporting period, with the effect of any changes in estimates being accounted for on a prospective basis.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

IMPAIRMENT OF LONG-LIVED ASSETS

The Company’s long-lived assets consist of property and equipment, operating lease-right of use assets and indefinite lived assets (i.e. trademarks and domain name). The Company evaluates long-lived assets for indicators of impairment at least annually or when events or changes in circumstances indicate that their carrying amounts may not be recoverable. The factors that would be considered by management in performing this assessment include current operating results, trends and prospects, the manner in which the long-lived asset is used and the effects of obsolescence, demand, competition and other economic factors. If indicators of impairment are identified, the Company performs an undiscounted cash flow analysis of the long-lived assets. Asset groups are written down only to the extent that their carrying value is lower than their respective fair value. Fair values of the asset group are determined by discounting the cash flows at a rate that approximates the cost of capital of a market participant.

Indefinite-lived intangible assets consist of trademarks and domain name. Indefinite-lived intangible assets are not amortized; rather they are tested for impairment at least annually, or more frequently if adverse events or changes in circumstances indicate that the carrying value may not be recoverable. In addition, management evaluates whether events and circumstances continue to support an indefinite useful life. Impairment tests are performed, at a minimum, in the fourth quarter of each year.

To test indefinite-lived intangible assets for impairment, the Company first assesses the qualitative factors to determine whether it is more likely than not that the fair value of the indefinite-lived intangible asset is less than its carrying amount as a basis for determining whether it is necessary to perform a quantitative impairment test. If the Company determines that it is more likely than not that the fair value of an indefinite-lived intangible asset is less than its carrying amount, then the quantitative impairment test is performed. The qualitative assessment requires the consideration of factors such as recent market transactions, macroeconomic conditions, and changes in projected future cash flows. The quantitative assessment compares the fair value of an indefinite-lived intangible asset to its carrying amount. If the carrying amount of an indefinite-lived intangible asset exceeds its fair value, an impairment loss is recognized for the excess. Fair values of indefinite-lived intangible assets are determined based on discounted cash flows.

The Company conducted an impairment analysis with respect to the casino room trademarks and HighRoller domain names at June 30, 2025, which concluded that the fair value, determined using a discounted cash flow analysis, substantially exceed their carrying value, and thus they were not impaired. Projected cash flows included an estimated commission fee for referring a player who opens an account with a deposit to an online gaming site, as well as future revenue sharing agreements for those customers based upon net gaming revenue over an estimated gaming period ranging from approximately 5 months to 12 months. The Company did not have any impairment of indefinite-lived intangible assets during the six months ended June 30, 2025 and 2024.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents, and Restricted Cash

Cash and cash equivalents consist of liquid checking and instant access internet banking accounts with original maturities of ninety days or less, as well as cash balances held with payment service providers, that are subject to an insignificant risk of change in value.

Cash and cash equivalents that are legally restricted as to withdrawal or usage are classified as current or non-current restricted cash, as applicable, in the consolidated balance sheets.

Entertainment, HR Entertainment and Interstellar Entertainment N.V. maintain separate accounts with various intermediary parties to segregate cash that resides in customers’ interactive gaming accounts from cash used in operating activities. Player funds denoted as such by Entertainment at the end of each period are classified as restricted cash. Player funds include cash amounts that reside in players’ interactive gaming withdrawals that were initiated by players but that are still pending at the end of each period, and the value of any bets that are unsettled at the end of each period.

Accounts Receivable, Related Party Transactions Policy [Policy Text Block]

DUE FROM AFFILIATES

Due from affiliates consists of amounts expected to be collected from certain affiliated companies under common control. Amounts due reflect the revenues recorded by the Company under intra-group services arrangements for maintenance and operations of the iCasino platform on behalf of Interactive. As of June 30, 2025 and December 31, 2024, due from affiliates primarily reflected amounts due from Spike Up and Happy Hour Entertainment Holdings (see Note 12). On a periodic basis, the Company evaluates the collectability of amounts due from affiliates and establishes an allowance for amounts not expected to be collected. No allowance was recorded for the periods presented in the consolidated financial statements.

Accounts Payable, Related Party Transactions Policy [Policy Text Block]

Due to AFFILIATES

Due to affiliates consists of amounts owed by the Company to certain of its related parties and affiliates. Amounts due to affiliates may include payment for services provided to the Company by employees of the related party or affiliate, or reimbursement of amounts paid by the related party or affiliate on the Company’s behalf.

Lessee, Leases [Policy Text Block]

Leases

The Company accounts for leases in accordance with ASC 842, Leases, under which arrangements meeting the definition of a lease are classified as operating or finance leases and are recorded on the consolidated balance sheets as both a right-of-use asset and a lease liability.

The Company elected to apply the practical expedient that allows for the combination of lease and non-lease components for all asset classes. The lease classification evaluation begins at the lease commencement date. The lease term used in the evaluation includes the non-cancellable period for which the Company has the right to use the underlying asset, together with renewal option periods when the exercise of the renewal option is reasonably certain.

For leases with an initial term greater than 12 months, a related lease liability is recorded on the balance sheet at the present value of future payments discounted at the estimated fully collateralized incremental borrowing rate (discount rate) corresponding with the lease term. In addition, a right-of-use asset is recorded as the initial amount of the lease liability, plus any lease payments made to the lessor before or at the lease commencement date and any initial direct costs incurred, less any tenant improvement allowance incentives received. Tenant incentives are amortized through the right-of-use asset as a reduction of rent expense over the lease term. The difference between the minimum rents paid and the straight-line rent is reflected within the associated right-of-use asset. Certain leases contain provisions that require variable payments consisting of common area maintenance costs (variable lease cost).Variable lease costs are expensed as incurred.

As the interest rate implicit in the lease is not readily determinable, the Company uses its incremental borrowing rate corresponding with the lease term. As the Company does not have any outstanding debt, this rate is determined based on prevailing market conditions and comparable company and credit analysis. The incremental borrowing rate is reassessed if there is a change to the lease term or if a modification occurs and it is not accounted for as a separate contract.

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign Currency and Foreign Exchange Risk

The condensed consolidated financial statements are presented in United States Dollars ($), which is the Company’s reporting currency.

Foreign currency exchange risk is the risk that the Company’s results of operations and/or financial condition could be impacted by unfavorable changes in exchange rates. The Company has transactions denominated in currencies other than the U.S. Dollar, principally the Euro but also other foreign currencies including Norwegian Krone, New Zealand Dollar and Canadian Dollar, that expose the Company’s operations to risk from the effects of exchange rate movements. Such movements may impact future revenues, expenses, and cash flows. Translation adjustments resulting from the process of translating the local currency financial statements into U.S. dollars are included in determining other comprehensive income. Changes in the value of the Company’s cash balance due to fluctuations in foreign exchange rate are presented in the unaudited condensed consolidated statements of cash flows as effect of foreign exchange rate changes on cash, cash equivalents, and restricted cash. As of June 30, 2025 and December 31, 2024, 83% and 33%, respectively, of the Company’s cash, cash equivalents and restricted cash reside in bank accounts located outside of the United States. The Company’s primary foreign currency exchange risk occurs between the time when other foreign currencies are exchanged for wagering on the Platform, and when those funds are settled to the Company in Euro. The relatively stable status of the Euro reduces but does not eliminate the Company’s exposure to foreign currency exchange risk. In addition, gains and losses related to translating certain cash balances from the Euro to the U.S. Dollar, as well as payable balances also impact net income. As the Company’s foreign operations expand, results may be impacted further by fluctuations in the exchange rates of the currencies in which the Company does business. The Company has not used any derivative financial instruments to manage its foreign currency exchange risk exposure.

In most of the Company’s operations, the Company transacts primarily in the Euro, including wagered amounts, net revenue, revenue share, and employee-related compensation costs. Operating arrangements with payment service providers who convert player funds to the Euro from other currencies, for example the Canadian Dollar, could further negatively impact foreign currency exchange risk if the exchange spot rates used are unfavorable as compared to European Central Bank exchange rates. Foreign currency gains and losses arising from transactions denominated in currencies other than the functional currency are included in net loss and are included within general and administrative expenses. For the six months ended June 30, 2025 and 2024, the Company incurred foreign currency transaction losses of $329 thousand and $715 thousand, respectively. For the three months ended June 30, 2025 and 2024, the Company incurred foreign currency transaction losses of $151 thousand and $250 thousand, respectively. While the Company expects these losses to persist through 2025, it continues to manage and negotiate contracts with payment providers.

The effects of foreign currency translation adjustments are included in stockholders’ equity as a component of accumulated other comprehensive loss in the accompanying condensed consolidated balance sheets. Foreign currency fluctuations between the functional and reporting currency can significantly impact the currency translation adjustment component of accumulated other comprehensive income.

Credit Risk

The Company’s credit risk arises from cash and cash equivalents, and restricted cash and deposits with banks and other financial institutions. The Company maintains balances in banks in the United States and outside of the United States, primarily within the European Union. For funds held within the United States, the Federal Deposit Insurance Corporation insures $250 thousand per depositor per FDIC insured bank. For funds held within the European Union, the European Deposit Insurance Scheme insures €100 thousand per depositor per bank. The Company has funds in Finland, Cyprus, Lithuania, and Malta that are protected under this scheme. The Company mitigates potential cash risk by diversifying bank accounts with insured banking institutions within the United States and European Union. Furthermore, the Company maintains cash in payment service provider accounts and other such financial institutions that may or may not be protected under the previously mentioned insurance schemes. The Company mitigates this potential risk by drawing down funds and transferring them to insured bank accounts on a regular basis. Any loss incurred or lack of access to such funds could have an adverse impact on the Company’s financial conditions, results of operations and cash flows period.
