Accounting Policies [Abstract]
Description of business	Description of business Background and nature of operations DoubleDown Interactive Co., Ltd. (“DDI,” “we,” “us,” “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. The remaining 32.9% of our outstanding shares are held by STIC Special Situation Private Equity Fund (“STIC”, 20.2%) and the remainder by other shareholders and participants in our IPO (12.7%). In 2017, DDI acquired DoubleDown Interactive, LLC (“DDI-US”) from International Gaming Technologies (“IGT”) for approximately $825 million. DDI-US, with its principal place of business located in Seattle, Washington, is our primary revenue-generating entity. We develop and publish digital gaming content 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. Acquisition of SuprNation AB On October 31, 2023, the Company closed the acquisition of iGaming operator, SuprNation AB (“SuprNation”), for a total cash consideration €34.3 million (or approximately $36.5 million based on an exchange rate of €1 = $1.064 as of October 27, 2023). The acquisition diversifies the digital games categories that the Company addresses with the addition of three real-money iGaming sites in Western Europe. Following the closing, SuprNation AB is now a direct, wholly-owned subsidiary of DDI-US. Basis of preparation and consolidation Our unaudited condensed consolidated financial statements (“financial statements”) have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) and the applicable rules and regulations of the Securities and Exchange Commission regarding interim financial information. Certain information and note disclosures normally included in the consolidated financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. Our unaudited condensed consolidated 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 financial statements should be read in conjunction with our consolidated financial statements for the year ended December 31, 2023. The condensed consolidated financial statements include the balances and accounts of DDI and our controlled subsidiaries. All significant inter-company transactions, balances and unrealized gains or losses have been eliminated. We view our operations and manage our business as one operating segment. Use of estimates The preparation of financial statements in conformity with Generally Accepted Accounting Principles (GAAP) requires estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and related disclosures. We regularly evaluate estimates and assumptions related to provisions for income taxes, revenue recognition, expense accruals, deferred income tax asset valuation allowances, valuation of goodwill and intangibles, and legal contingencies. 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. Functional currency and translation of financial statements Our functional currency is the Korean Won (“KRW”), and Euro (“EUR” or “€”) and the U.S. Dollar (“dollar,” “USD,” “US$,” or “$”) are the functional currencies of our subsidiaries in Europe and United States, respectively. The accompanying consolidated financial statements are presented in USD. The consolidated balance sheets have been translated at the exchange rates prevailing at each balance sheet date. The consolidated statement of comprehensive income and statement of cash flows have been translated using the weighted-average exchange rates prevailing during the periods of each statement. The equity capital is denominated in the functional currency, KRW, and is translated at historical exchange rates. All translation adjustments resulting from translating into the reporting currency are accumulated as a separate component of accumulated other comprehensive income in shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in other income (expense). Intercompany monetary items denominated in foreign currencies are translated into the functional currency at the exchange rate at the reporting date with the gain or loss arising on translation recorded to other income (expense). Intercompany non-monetary items that are measured at historical cost in a foreign currency are translated using the exchange rates at the dates of the initial transactions. Cash and cash equivalents We consider all money market funds and short-term investments with a maturity of three months or less when acquired to be cash and cash equivalents. Cash and cash equivalents are held by high credit quality financial institutions and balances may exceed limits of federal insurance. We have not experienced any losses resulting from these excess deposits. Financial instruments and concentration of credit risk Financial instruments, which potentially expose us to concentrations of credit risk, consist primarily of cash and cash equivalents, accounts receivable and short-term investments. Accounts receivable are recorded and carried at the net invoiced amount, which is net of platform payment processing fees, unsecured, and represent amounts due to us based on contractual obligations where an executed contract exists. For our social-casino/free-to-play games, we generally do not require collateral and have not recognized an allowance as management estimates the net receivable is fully collectible. Apple, Inc. (“Apple”), Facebook, Inc. (“Facebook”), and Google, LLC (“Google”) represent significant distribution, marketing, and payment platforms for our games. A substantial portion of our revenue was generated from players who accessed our games through these platforms and a significant concentration of our accounts receivable balance is comprised of balances owed to us by these platforms. The following table summarizes the percentage of revenues and accounts receivable generated via our platform providers in excess of 10% of our total revenues and total accounts receivable: Revenue Concentration Three months ended June 30, Six months ended June 30, 2024 2023 2024 2023 Apple 51.0 % 55.4 % 50.6 % 55.3 % Google 16.1 % 18.9 % 16.1 % 18.8 % Facebook 14.5 % 16.9 % 14.6 % 17.7 % Accounts Receivable Concentration As of June 30, As of December 31, 2024 2023 Apple 57.8 % 59.3 % Xsolla 11.9 % 11.3 % Google 9.5 % 10.3 % Facebook 8.4 % 9.9 %

Revenue from Contracts with Cus

Revenue from Contracts with Customers	6 Months Ended

Revenue from Contract with Customer [Abstract]
Revenue from Contracts with Customers	Revenue from Contracts with Customers Our social and mobile apps operate on a free-to-play model, whereby game players may collect virtual currency free of charge through the passage of time or through targeted marketing promotions. If a game player wishes to obtain virtual currency above and beyond the level of free virtual currency available to that player, the player may purchase additional virtual currency. Once a purchase is completed, the virtual currency is deposited into the player’s account and is not separately identifiable from previously purchased virtual currency or virtual currency obtained by the game player for free. Once obtained, virtual currency (either free or purchased) cannot be redeemed for cash nor exchanged for anything other than gameplay within our apps. When virtual currency is played on any of our games, the game player could “win” and would be awarded additional virtual currency or could “lose” and lose the future use of that virtual currency. We have concluded that our virtual currency represents consumable goods, because the game player does not receive any additional benefit from the games and is not entitled to any additional rights once the virtual currency is substantially consumed. Control transfers when the virtual currency is consumed for gameplay. We recognize revenue from player purchases of virtual currency based on the consumption of this currency. We determined through a review of play behavior that game players generally do not purchase additional virtual currency until their existing virtual currency balances, regardless of source (e.g., bonus currency, gifted currency through social media channels, daily free chips, etc.), have been substantially consumed. Based on an analysis of customers’ historical play behavior, purchase behavior, and the amount of virtual currency outstanding, we are able to estimate the rate that virtual currency is consumed during gameplay. Accordingly, revenue is recognized using a user-based revenue model with the period between purchases representing the timing difference between virtual currency purchase and consumption. This timing difference is relatively short. We continuously gather and analyze detailed customer play behavior and assess this data in relation to our judgments used for revenue recognition. We generate a small portion of our revenue from subscription services. All monthly subscription fees are prepaid and non-refundable for a one-month period and auto-renew until the end customer terminates the service with the platform provider the subscription services originated. The subscription revenue is recognized on a daily basis beginning on the original date of purchase and has no impact on a customer purchased virtual currency. Disaggregation of revenue 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.

Principal-agent considerations Our revenue contracts are with game players who are our customers. We have exclusive control over all content, pricing, and overall functionality of games accessed by players. Our games are played on various third-party platforms for which the platform providers collect proceeds from our customers and remit us an amount after deducting a fee for processing and other agency services. We record revenue at the gross amount charged to our customers and classify fees paid to platform providers (such as Apple, Facebook, and Google) within cost of revenue, contract assets, contract liabilities and other disclosures. Contract assets, contract liabilities and other disclosures Customer payments are based on the payment terms established in our contracts. Payments for purchase of virtual currency are required at time of purchase, are non-refundable and relate to non-cancellable contracts that specify our performance obligations. All payments are initially recorded as revenue, as the player has no right of return after the purchase, consistent with our standard terms and conditions. Based on our analysis, at each period end, we estimate the number of days to consume virtual currency. This represents the revenue amount where the performance obligation has not been met and is deferred as a contract liability until we satisfy the obligation. The contract asset consists of platform fees for which revenue has not been recognized. For subscription revenue, the remaining portion of the daily ratable monthly subscription is recorded as a contract liability and the applicable platform fees as a contract asset. The following table summarized our opening and closing balances in contract assets and contract liabilities (in thousands): As of June 30, As of December 31, 2024 2023 Contract assets (1) $ 533 $ 756 Contract liabilities 1,777 2,520 (1) Contract assets are included within prepaid expenses and other assets in our consolidated balance sheet.

Income Tax Disclosure [Abstract]
Income taxes	Income taxes We are subject to federal and state income taxes in Korea, the United States, Malta and Sweden. We account for our provision for income taxes in accordance with ASC 740, Income Taxes, which requires an estimate of the annual effective tax rate for the full year to be applied to the interim period, taking into account year-to-date amounts and projected results for the full year. Our effective tax rate varies from the statutory Korean income tax rate due to the effect of foreign rate differential, withholding taxes, state and local income taxes, notional interest deduction, FDII deduction, and valuation allowances on deferred tax assets in certain jurisdictions. Our effective tax rate could fluctuate significantly from quarter to quarter based on variations in the estimated and actual level of pre-tax income or loss by jurisdiction, changes in enacted tax laws and regulations, and changes in estimates regarding non-deductible expenses and tax credits. As of June 30, 2024, and December 31, 2023, we have provided a valuation allowance against our net deferred tax assets that we believe, based on the weight of available evidence, are not more likely than not to be realized. The income tax expense of $17.4 million for the six months ended June 30, 2024, reflects an effective tax rate of 21.4% which is lower than the effective tax rate of 23.7% for the six months ended June 30, 2023. The decrease in rate from 2023 to 2024 is primarily due to an increase in the FDII benefit and notional interest deduction.
