General Information [Abstract]
General information	General information Background and nature of operations DoubleDown Interactive Co., Ltd. (“DDI,” “we,” “us,” “Parent Company,” “our” or “the Company,” formerly known as The8Games Co., Ltd.) was incorporated in 2008 in Seoul, Korea as an interactive entertainment studio, focused on the development and publishing of casual games and mobile applications. DDI is a subsidiary of DoubleU Games Co., Ltd. (“DUG” or “DoubleU Games”), a Korean company and our controlling shareholder holding 67.1% of our outstanding shares. In 2017, DDI acquired Double Down Interactive, LLC (“DDI-US”) from International Gaming Technologies (“IGT”) for approximately $825 million. DDI-US is our primary revenue-generating company. In October 2023, the Company acquired an iGaming operator, SuprNation AB (together with its subsidiaries, “SuprNation”), which is now a direct, wholly-owned subsidiary of DDI-US. The acquisition diversifies the digital games categories that the Company addresses with the addition of three real-money iGaming sites in Europe. In July 2025, the Company acquired WHOW Games GmbH, a social casino developer headquartered in Hamburg, Germany (“WHOW Games”), which is now a direct, wholly-owned subsidiary of DDI-US. In September 2025, DDI-US completed the conversion from a Washington limited liability company to a Nevada limited liability company. We develop and publish digital gaming contents on various mobile and web platforms through our multi-format interactive all-in-one game experience concept. We host DoubleDown Casino, DoubleDown Classic, and DoubleDown Fort Knox within various formats, SuprNation’s three brands, Duelz, VoodooDreams, and NYSpins, on web platforms, and WHOW Game’s proprietary brands, mainly MyJackpot and Lounge777, and licensed brand, mainly Merkur24, on both web and mobile platforms. On September 2, 2021, we completed our initial public offering (“IPO”) of American Depositary Shares (“ADSs”), each representing 0.05 share of a common share, with par value of ₩10,000 per share, of the Company. Our ADSs trade on the NASDAQ Stock Market (“NASDAQ”) under the symbol “DDI.”

Acquisition

Business Combination – WHOW Games

On July 14, 2025 (July 15, 2025 Korea Standard Time), the Company completed its acquisition of WHOW Games GmbH (“WHOW Games”), a social casino developer headquartered in Hamburg, Germany, which is now a direct, wholly-owned subsidiary of DDI-US, for a total cash purchase consideration of €55.0 million (or approximately $64.3 million based on the then exchange rate). Contemporaneously with entering into the definitive agreement, the Company also adopted a twenty-four-month performance-based incentive plan for an additional earn-out payment of up to €10.0 million, payable to the seller, Azerion, at €5.0 million annually, which is contingent upon WHOW Games meeting certain performance targets during each of the first and second year following the closing date.

The following table summarizes the allocation of the purchase consideration to the acquisition-date fair value of the assets acquired and liabilities assumed (in thousands):


Ⅰ. Total purchase consideration	$	64,283
Ⅱ. Identifiable Assets and liabilities, net	28,157
Cash and cash equivalents	2,714

Current lease liabilities	(1,232)
Other current liabilities	(516)
Deferred tax liabilities	(9,888)
Ⅲ. Goodwill (Ⅰ-Ⅱ)	$	36,126

Goodwill represents the excess of the purchase price over the preliminary fair value of identifiable assets acquired and liabilities assumed at the acquisition date and is primarily attributable to the assembled workforce and expected synergies at the time of the acquisition. The allocation of the purchase price is still provisional and subject to change within the measurement period, including potential adjustments to deferred tax balances.

Accounting Policies, Changes In Accounting Estimates and Errors [Abstract]
Basis of preparation	The accompanying condensed consolidated interim financial statements are presented in conformity with International Financial Reporting Standards (“IFRS Accounting Standards”) as issued by International Accounting Standard Board (“IASB”), and include the accounts of DDI and its controlled subsidiaries. All intercompany transactions, balances, and unrealized gains or losses have been eliminated. Our unaudited condensed consolidated interim financial statements include all adjustments of a normal, recurring nature necessary for the fair statement of the results for the interim periods presented. The results for the interim period presented are not necessarily indicative of those for the full year. The condensed consolidated interim financial statements should be read in conjunction with our consolidated financial statements for the year ended December 31, 2024.
Use of estimates	The preparation of financial statements in conformity with IFRS requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and the actual results, future operating results may be affected. The significant accounting estimates and assumptions used in the preparation of these condensed consolidated interim financial statements are consistent with those applied in the preparation of the annual consolidated financial statements for the year ended December 31, 2024, except for the estimation method used in determining income tax expense and those newly applied in relation to the business combination during the interim period ended September 30, 2025. The income tax expense for the interim period is calculated by applying the estimated average annual effective tax rate to the profit before tax for the period.
New standards and interpretations adopted during the interim period	Amendments to IAS 21 - Lack of Exchangeability The amendment to IAS 21 The Effects of Changes in Foreign Exchange Rates will require the application of a consistent approach when assessing whether a currency can be exchanged for another currency and, when it cannot, determining the exchange rate to be used, and the related disclosures. The amendments are effective for annual reporting periods beginning on or after January 1, 2025, with earlier adoption permitted. The adoption of these amendments does not have a material impact on the Company’s condensed consolidated interim financial statements.

15.2. Disaggregation of revenue and non-current assets

The Company’s business operations are located in domestic and international regions, including the United States. We believe disaggregation of our revenue based on platform and geographical location are appropriate categories that depict how the nature, amount, timing, and uncertainty of revenue and cash flows are affected by economic factors.

The following table presents our revenue disaggregated based on the geographical location of our players (in thousands):

Accounting Policies, Changes In Accounting Estimates and Errors [Abstract]
Basis of preparation and material accounting policies	Basis of preparation and material accounting policies Basis of preparation The accompanying condensed consolidated interim financial statements are presented in conformity with International Financial Reporting Standards (“IFRS Accounting Standards”) as issued by International Accounting Standard Board (“IASB”), and include the accounts of DDI and its controlled subsidiaries. All intercompany transactions, balances, and unrealized gains or losses have been eliminated. Our unaudited condensed consolidated interim financial statements include all adjustments of a normal, recurring nature necessary for the fair statement of the results for the interim periods presented. The results for the interim period presented are not necessarily indicative of those for the full year. The condensed consolidated interim financial statements should be read in conjunction with our consolidated financial statements for the year ended December 31, 2024. Use of estimates The preparation of financial statements in conformity with IFRS requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures. We base our estimates and assumptions on current facts, historical experience, and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the accrual of costs and expenses that are not readily apparent from other sources. The actual results experienced may differ materially and adversely from these estimates. To the extent there are material differences between the estimates and the actual results, future operating results may be affected. The significant accounting estimates and assumptions used in the preparation of these condensed consolidated interim financial statements are consistent with those applied in the preparation of the annual consolidated financial statements for the year ended December 31, 2024, except for the estimation method used in determining income tax expense and those newly applied in relation to the business combination during the interim period ended September 30, 2025. The income tax expense for the interim period is calculated by applying the estimated average annual effective tax rate to the profit before tax for the period. Accounting policies The accounting policies applied in the preparation of these condensed consolidated interim financial statements are consistent with those applied in the preparation of the consolidated financial statements as of and for the year ended December 31, 2024, except for the adoption of new standards or interpretations effective from January 1, 2025. New standards and interpretations adopted during the interim period Amendments to IAS 21 - Lack of Exchangeability The amendment to IAS 21 The Effects of Changes in Foreign Exchange Rates will require the application of a consistent approach when assessing whether a currency can be exchanged for another currency and, when it cannot, determining the exchange rate to be used, and the related disclosures. The amendments are effective for annual reporting periods beginning on or after January 1, 2025, with earlier adoption permitted. The adoption of these amendments does not have a material impact on the Company’s condensed consolidated interim financial statements.

Commitments and contingencies	Sep. 30, 2025
Capital commitments [abstract]
Commitments and contingencies	Commitments and contingencies 13.1. Publishing and license agreements DoubleU Games We entered into the DoubleU Games License Agreement on March 7, 2018, which was subsequently amended on July 1, 2019 and November 27, 2019. On October 1, 2023, DDI-US entered into the Game Development Services Agreement with DoubleU Games, which supersedes the DoubleU Games License Agreement. Pursuant to the Game Development Services Agreement, DoubleU Games grants us, through DDI-US, an exclusive license to develop and distribute certain DoubleU Games social casino game titles and sequels thereto in the social online game field of use. We are obligated to pay a royalty license fee to DoubleU Games in connection with these rights, with certain customary terms and conditions. As of September 30, 2025, we licensed from DUG approximately 61 game titles under the terms of this agreement. In October 2023, we, through DDI-US, entered into a Game Development Services Agreement with DoubleU Games pursuant to which DDI-US will pay service fees to DoubleU Games for certain game maintenance services and product planning and user analysis services provided by DoubleU Games. We, through SuprPlay Limited, also entered into a new game license agreement with DoubleU Games with effect from August 20, 2024. We are obligated to pay a royalty license fee to DoubleU Games in connection with these rights, with certain customary terms and conditions. International Gaming Technologies (“IGT”) In 2017, we entered into a Game Development, Distribution, and Services Agreement with IGT. Under the terms of the agreement, IGT will deliver game assets so that we can port (a process of converting the assets into functioning slot games by platform) the technology for inclusion in our gaming apps. The agreement includes game assets that are used to create new games. Under the agreement, we paid IGT an initial royalty rate of 10% of revenue for their proprietary assets and 15% of revenue for third-party game asset types. Effective January 1, 2019, we amended the agreement to revise the royalty rate for proprietary game asset types to 7.5% of revenue. The initial term of the agreement is ten (10) years with up to two additional five-year periods. Costs incurred in connection with this agreement for the nine months ended September 30, 2025 and 2024 totaled $2.1 million and $3.4 million, respectively, and are recognized as a component of cost of revenue. 13.2. Legal contingencies As of September 30, 2025, the Company is a defendant in four lawsuits seeking damages, filed in the states of Alabama, Kentucky, and Tennessee. These lawsuits allege that the Company’s social casino-themed games constitute unlawful gambling under state laws. The Company denies the allegations, contends its games are not gambling under the applicable law, and contends that the case suffers from various procedural defects. At this time, the Company is unable to reasonably predict the outcome of these legal proceedings and cannot estimate what impact, if any, the litigation may have on the Company’s condensed consolidated interim financial statements. 13.3. Director and Officers’ indemnification agreement The Company’s maximum aggregate liability for all loss and expenses on account of any and all requests for indemnity under the Indemnification Agreement or any similar indemnity agreement with any other indemnitee will be $5,000,000 per every 12-month period. 13.4. Other matters IGT Letter In March 2025, DDI-US received a letter from IGT (“IGT Letter”) purporting to terminate the Company’s licenses to develop and distribute IGT social casino game titles throughout the United States. The IGT Letter cited the January 2025 public memo issued by the Washington State Gambling Commission (“WSGC”), where the WSGC encouraged companies offering virtual casino-style games to Washington residents to review their games and ensure compliance with state gambling regulations. While the outcome of this matter is currently uncertain, the Company believes that IGT has no basis to terminate the licenses and that the Company’s distribution of the licensed games is not prohibited under Washington State law. SuprNation Performance Based Compensation Contemporaneously with entering into the definitive agreement, the Company also adopted an eighteen-month performance-based incentive plan for certain key employees of SuprNation, under which the key employees may earn up to a total of $6.5 million in addition to $5.5 million held in escrow, which vest over the eighteen-month period. The performance-based incentive plan is contingent upon the achievement of certain revenue and other performance targets by the acquired business and the continued employment of such key employees between 2023 and 2025. Such plan became effective at the closing of the transaction. In August 2024, $4.2 million of the incentive plan was modified to be contingent solely upon continued employment. During nine months ended September 30, 2025 and 2024, the Company recognized total expenses of $2.5 million and $5.0 million, respectively, for the performance-based incentive plan. All of the compensation under the plan has been paid as of September 2025.
