Ladies and Gentlemen:

DoubleDown Interactive Co., Ltd., a corporation organized under the laws of the Republic of Korea (“Korea”) (the “Company”), whose controlling stockholder is DoubleU Games Co., Ltd. (the “Parent”), proposes to issue and sell to the several underwriters listed in Schedule 1 hereto (the “Underwriters”), an aggregate of 263,150 common shares, with par value of W10,000 per share, of the Company (the “Common Shares”) in the form of 5,263,000 American Depositary Shares (the “ADSs”), each ADS representing 0.05 Common Share (the “Subscription Securities”) and STIC Special Situation Diamond Limited (the “Selling Stockholder”) proposes to issue and sell to the Underwriters an aggregate of 52,650 Common Shares in the form of 1,053,000 ADSs (the “Sale Securities” and, together with the “Subscription Securities”, the “Underwritten Securities”). In addition, STIC Special Situation Diamond Limited (the “Selling Stockholder”) proposes to sell, at the option of the Underwriters, up to an additional 947,400 ADSs (the “Option Securities”). The Underwritten Securities and the Option Securities are herein referred to as the “Securities”.

The ADSs will be evidenced by American Depositary Receipts (“ADRs”) issued pursuant to a Deposit Agreement, dated as of September 2, 2021 (the “Deposit Agreement”), among the Company, Citibank, N.A. as Depositary (the “Depositary”), and all holders from time to time of ADRs issued thereunder. The Common Shares of the Company represented by the ADSs are hereinafter referred to as the “Underlying Shares.”

The Company and the Selling Stockholder hereby confirm their agreement with the several Underwriters concerning the purchase and sale of the Securities, as follows:

1. Registration Statement. The Company has prepared and filed with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Securities Act”), a registration statement on Form F-1 (File No. 333-258032), including a prospectus, relating to the Underlying Shares. Such registration statement, as amended at the time it became effective, including the information, if any, deemed pursuant to Rule 430A, 430B or 430C under the Securities Act to be part of the registration statement at the time of its effectiveness (“Rule 430 Information”), is referred to herein as the “Registration Statement”; and as used herein, the term “Preliminary Prospectus” means each prospectus included in such registration statement (and any amendments thereto) before effectiveness, any prospectus filed with the Commission pursuant to Rule 424(a) under the Securities Act and the prospectus included in the Registration Statement at the time of its effectiveness that omits Rule 430 Information, and the term “Prospectus” means the prospectus in the form first used (or made available upon request of purchasers pursuant to Rule 173 under the Securities Act) in connection with confirmation of sales of the Securities. If the Company has filed an abbreviated registration statement pursuant to Rule 462(b) under the Securities Act (the “Rule 462 Registration Statement”), then any reference herein to the term “Registration Statement” shall be deemed to include such Rule 462 Registration Statement. Capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement and the Prospectus.

The Company and the Depositary have also jointly filed with the Commission a registration statement on Form F-6 (File No. 333-239022), including a prospectus, which may be in the form of an ADR certificate (the “Registration Statement on Form F-6”), for the registration under the Securities Act of the ADSs evidenced by ADRs, have filed such amendments thereto and such amended prospectuses as may have been required to the date hereof, and will file such additional amendments thereto and such amended prospectuses as may hereafter be required. The Registration Statement on Form F-6, as amended at the time it becomes effective (including by the filing of any post-effective amendments thereto), and the prospectus included therein, as then amended, is hereinafter called the “ADR Registration Statement” and the “ADR Prospectus,” respectively.

At or prior to the Applicable Time (as defined below), the Company had prepared the following information (collectively with the pricing information set forth on Annex A, the “Pricing Disclosure Package”): a Preliminary Prospectus dated August 20, 2021, and each “free-writing prospectus” (as defined pursuant to Rule 405 under the Securities Act) listed on Annex A hereto.

“Applicable Time” means 6:18 p.m., New York City time, August 30, 2021.

2. Korean Securities Registration Statement and Prospectus. The Company has prepared and filed with the Financial Services Commission of Korea (the “FSC”) a securities registration statement and prospectus in the Korean language, in accordance with the Financial Investment Services and Capital Markets Act of Korea (the “FSCMA”). Such securities registration statement, as amended at the time it became effective, shall be referred to herein as the “K-SRS” and such prospectus, as amended at the time it became effective, shall be referred to herein as the “K-Prospectus.”

3. Purchase of the Securities. The Company agrees to issue and sell the Subscription Securities, and the Selling Stockholder agrees to sell the Sale Securities, to the several Underwriters as provided in this underwriting agreement (this “Agreement”), and each Underwriter, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, agrees, severally and not jointly, to purchase at a price per ADS of $16.74 (the “ADS Purchase Price”), which represents the public offering price of $18.00 per ADS minus an underwriting discount of $1.26 per ADS, from the Company and the Selling Stockholder the respective number of Subscription Securities and Sale Securities set forth opposite such Underwriter’s name in Schedule 1 hereto.

In addition, the Selling Stockholder agrees, as and to the extent indicated in Schedule 2 hereto, to sell, the Option Securities to the several Underwriters as provided in this Agreement, and the Underwriters, on the basis of the representations, warranties and agreements set forth herein and subject to the conditions set forth herein, shall have the option to purchase, severally and not jointly, from the Selling Stockholder the Option Securities at the ADS Purchase Price less an amount per share equal to any dividends or distributions declared by the Company and payable on the Underwritten Securities but not payable on the Option Securities.

(b) Indemnification of the Underwriters by the Selling Stockholder. The Selling Stockholder agrees to indemnify and hold harmless each Underwriter, its affiliates, directors and officers and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the indemnity set forth in paragraph (a) above but only with respect to such losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission of a material fact made in reliance upon and in conformity with any information relating to the Selling Stockholder furnished to the Company in writing by the Selling Stockholder expressly for use in the K-SRS, the K-Prospectus, the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication or the Pricing Disclosure Package, it being understood and agreed that the only such information furnished by the Selling Stockholder consists of (i) the legal name, address and the number of Common Shares beneficially owned by the Selling Stockholder, before and after the offering, and (ii) the other information with respect to the Selling Stockholder appearing in the section “Principal and selling stockholders” in each case, in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, or any Issuer Free Writing Prospectus (collectively, the “Selling Stockholder Information”).

36

(c) Indemnification of the Company and the Selling Stockholder. Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Company, its directors, its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the indemnity set forth in paragraph (a) above and the Selling Stockholder to the same extent as the indemnity set for the in paragraph (b) above, but only with respect to any losses, claims, damages or liabilities that arise out of, or are based upon, any untrue statement or omission or alleged untrue statement or omission of a material fact made in reliance upon and in conformity with any information relating to such Underwriter furnished to the Company in writing by such Underwriter through the Representative expressly for use in the Registration Statement, the Prospectus (or any amendment or supplement thereto), any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Written Testing-the-Waters Communication, any road show or any Pricing Disclosure Package (including any Pricing Disclosure Package that has subsequently been amended), it being understood and agreed upon that the only such information furnished by any Underwriter consists of (A) the following information in the Prospectus furnished on behalf of each Underwriter: (i) the names of the Underwriters set forth on the cover and under the caption “Underwriting,” (ii) the concession and discount figures in the third paragraph under the caption “Underwriting”, and (iii) the information contained in the second, third and fourth paragraphs under the caption “Underwriting—Price stabilization, short positions and penalty bids” (collectively, the “U.S. Underwriter Information”) and (B) the following information in the K-SRS and the K-Prospectus furnished on behalf of each Underwriter: the names of the Underwriters set forth on the cover and under the caption “Underwriting (“모집 또는 매출에 관한 사항 – 모집 또는 매출에 관한 일방 사항 – 공모개요”)” (the “Korean Underwriter Information” and, together with the U.S. Underwriter Information, the “Underwriter Information”).

37

(d) Notice and Procedures. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought or asserted against any person in respect of which indemnification may be sought pursuant to the preceding paragraphs of this Section 10, such person (the “Indemnified Person”) shall promptly notify the person against whom such indemnification may be sought (the “Indemnifying Person”) in writing; provided that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have under the preceding paragraphs of this Section 10 except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided, further, that the failure to notify the Indemnifying Person shall not relieve it from any liability that it may have to an Indemnified Person otherwise than under the preceding paragraphs of this Section 10. If any such proceeding shall be brought or asserted against an Indemnified Person and it shall have notified the Indemnifying Person thereof, the Indemnifying Person shall retain counsel reasonably satisfactory to the Indemnified Person (who shall not, without the consent of the Indemnified Person, be counsel to the Indemnifying Person) to represent the Indemnified Person and any others entitled to indemnification pursuant to this Section that the Indemnifying Person may designate in such proceeding and shall pay the fees and expenses in such proceeding and shall pay the fees and expenses of such counsel related to such proceeding, as incurred. In any such proceeding, any Indemnified Person shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such Indemnified Person unless (i) the Indemnifying Person and the Indemnified Person shall have mutually agreed to the contrary; (ii) the Indemnifying Person has failed within a reasonable time to retain counsel reasonably satisfactory to the Indemnified Person; (iii) the Indemnified Person shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the Indemnifying Person; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the Indemnifying Person and the Indemnified Person and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. It is understood and agreed that the Indemnifying Person shall not, in connection with any proceeding or related proceeding in the same jurisdiction, be liable for the fees and expenses of more than one separate firm (in addition to one local counsel in each applicable jurisdiction) for all Indemnified Persons, and that all such fees and expenses shall be promptly paid or reimbursed as they are incurred. Any such separate firm for any Underwriter, its affiliates, directors and officers and any control persons of such Underwriter shall be designated in writing by the Representative and any such separate firm for the Company, its directors, its officers who signed the Registration Statement and any control persons of the Company shall be designated in writing by the Company and any such separate firm for the Selling Stockholder shall be designated in writing by the Attorneys-in-Fact or any one of them. The Indemnifying Person shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent, the Indemnifying Person agrees to indemnify each Indemnified Person from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an Indemnified Person shall have requested that an Indemnifying Person reimburse the Indemnified Person for fees and expenses of counsel as contemplated by this paragraph, the Indemnifying Person shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by the Indemnifying Person of such request and (ii) the Indemnifying Person shall not have reimbursed the Indemnified Person in accordance with such request prior to the date of such settlement. No Indemnifying Person shall, without the written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Indemnified Person is or could have been a party and indemnification could have been sought hereunder by such Indemnified Person, unless such settlement (x) includes an unconditional release of such Indemnified Person, in form and substance reasonably satisfactory to such Indemnified Person, from all liability on claims that are the subject matter of such proceeding and (y) does not include any statement as to or any admission of fault, culpability or a failure to act by or on behalf of any Indemnified Person.

38

(e) Contribution. If the indemnification provided for in paragraphs (a), (b) or (c) above is unavailable to an Indemnified Person or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each Indemnifying Person under such paragraph, in lieu of indemnifying such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Selling Stockholder, on the one hand, and the Underwriters on the other, from the offering of the Securities or (ii) if the allocation provided by clause (i) is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company and the Selling Stockholder, on the one hand, and the Underwriters on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Selling Stockholder, on the one hand, and the Underwriters on the other, shall be deemed to be in the same respective proportions as the net proceeds (before deducting expenses) received by the Company and the Selling Stockholder from the sale of the Securities and the total underwriting discounts and commissions received by the Underwriters in connection therewith, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate offering price of the Securities. The relative fault of the Company and the Selling Stockholder, on the one hand, and the Underwriters on the other, shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company and the Selling Stockholder or by the Underwriters, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(f) Limitation on Liability. The Company, the Selling Stockholder and the Underwriters agree that it would not be just and equitable if contribution pursuant to paragraph (e) above were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purposes) or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (e) above. The amount paid or payable by an Indemnified Person as a result of the losses, claims, damages and liabilities referred to in paragraph (e) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Person in connection with any such action or claim. Notwithstanding the provisions of paragraphs (e) and (f), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute pursuant to paragraphs (e) and (f) are several in proportion to their respective purchase obligations hereunder and not joint.

39

(g) Non-Exclusive Remedies. The remedies provided for in this Section 10 paragraphs (a) through (f) are not exclusive and shall not limit any rights or remedies which may otherwise be available to any Indemnified Person at law or in equity.

11. Effectiveness of Agreement. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto on the date first written above.

12. Termination. This Agreement may be terminated in the absolute discretion of the Representative, by notice to the Company and the Selling Stockholder, if after the execution and delivery of this Agreement and on or prior to the Closing Date or, in the case of the Option Securities, prior to the Additional Closing Date (i) trading generally shall have been suspended or materially limited on or by any of the New York Stock Exchange, The Nasdaq Stock Market or the Korea Exchange; (ii) trading of any securities issued or guaranteed by the Company shall have been suspended on any exchange or in any over-the-counter market; (iii) a general moratorium on commercial banking activities shall have been declared by U.S. federal or New York State or Korean authorities; or (iii) there shall have occurred any outbreak or escalation of hostilities or any change in financial markets or any calamity or crisis, either within or outside the United States or Korea, that, in the judgment of the Representative, is material and adverse and makes it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities on the Closing Date or the Additional Closing Date, as the case may be, on the terms and in the manner contemplated by this Agreement, the Pricing Disclosure Package and the Prospectus.

13. Defaulting Underwriter.

(a) If, on the Closing Date or the Additional Closing Date, as the case may be, any Underwriter defaults on its obligation to purchase the Securities that it has agreed to purchase hereunder on such date, the non-defaulting Underwriters may in their discretion arrange for the purchase of such Securities by other persons satisfactory to the Company and the Selling Stockholder on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Securities, then the Company and the Selling Stockholder shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Securities on such terms. If other persons become obligated or agree to purchase the Securities of a defaulting Underwriter, either the non-defaulting Underwriters or the Company and the Selling Stockholder may postpone the Closing Date or the Additional Closing Date, as the case may be, for up to five full business days in order to effect any changes that in the opinion of counsel for the Company, counsel for the Selling Stockholder or counsel for the Underwriters may be necessary in the Registration Statement and the Prospectus or in any other document or arrangement, and the Company agrees to promptly prepare any amendment or supplement to the Registration Statement and the Prospectus that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context otherwise requires, any person not listed in Schedule 1 hereto that, pursuant to this Section 13, purchases Securities that a defaulting Underwriter agreed but failed to purchase.

40

(b) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholder as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, does not exceed one-eleventh of the aggregate number of Securities to be purchased on such date, then the Company and the Selling Stockholder shall have the right to require each non-defaulting Underwriter to purchase the number of Securities that such Underwriter agreed to purchase hereunder on such date plus such Underwriter’s pro rata share (based on the number of Securities that such Underwriter agreed to purchase on such date) of the Securities of such defaulting Underwriter or Underwriters for which such arrangements have not been made.

(c) If, after giving effect to any arrangements for the purchase of the Securities of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters, the Company and the Selling Stockholder as provided in paragraph (a) above, the aggregate number of Securities that remain unpurchased on the Closing Date or the Additional Closing Date, as the case may be, exceeds one-eleventh of the aggregate amount of Securities to be purchased on such date, or if the Company and the Selling Stockholder shall not exercise the right described in paragraph (b) above, then this Agreement or, with respect to any Additional Closing Date, the obligation of the Underwriters to purchase Securities on the Additional Closing Date, as the case may be, shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 13 shall be without liability on the part of the Company, except that the Company and the Selling Stockholder will continue to be liable for the payment of expenses as set forth in Section 14 hereof and except that the provisions of Section 10 hereof shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company and the Selling Stockholder or any non-defaulting Underwriter for damages caused by its default.

14. Payment of Expenses.

(a) Whether or not the transactions contemplated by this Agreement are consummated or this Agreement is terminated, the Company will pay or cause to be paid all costs and expenses incident to the performance of its obligations hereunder, including without limitation:

41

(b) Notwithstanding anything in clause (a) above, it is understood and agreed, however, that:

15. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers and directors and any controlling persons referred to herein and the affiliates of each Underwriter referred to in Section 10 hereof. Nothing in this Agreement is intended or shall be construed to give any other person any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein. No purchaser of Securities from the Underwriter shall be deemed to be a successor merely by reason of such purchase.

42

16. Survival. The respective indemnities, rights of contribution, representations, warranties and agreements of the Company, the Selling Stockholder and the Underwriters contained in this Agreement or made by or on behalf of the Company, the Selling Stockholder or the Underwriters pursuant to this Agreement or any certificate delivered pursuant hereto shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination of this Agreement or any investigation made by or on behalf of the Company, the Selling Stockholder or the Underwriters or the directors, officers, controlling persons or affiliates referred to in Section 10 hereof.

17. Certain Defined Terms. For purposes of this Agreement, (a) except where otherwise expressly provided, the term “affiliate” has the meaning set forth in Rule 405 under the Securities Act; (b) the term “business day” means any day other than a day on which banks are permitted or required to be closed in New York City or Seoul; and (c) the term “subsidiary” has the meaning set forth in Rule 405 under the Securities Act.

18. Compliance with USA Patriot Act. In accordance with the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Underwriters are required to obtain, verify and record information that identifies their respective clients, including the Company and the Selling Stockholder, which information may include the name and address of their respective clients, as well as other information that will allow the Underwriters to properly identify their respective clients.

Each of the Company and the Selling Stockholder hereby represent and warrant that such authorized agent has accepted such appointment and has agreed to act as such authorized agent for service of process. Each of the Company and the Selling Stockholder further agree to take any and all action as may be necessary to maintain such designation and appointment of such authorized agent in full force and effect for a period of seven years from the date of this Agreement.

The Company and the Selling Stockholder agree to indemnify each Underwriter, its directors, officers, affiliates and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, against any loss incurred by such Underwriter as a result of any judgment or order being given or made for any amount due hereunder and such judgment or order being expressed and paid in a currency (the “judgment currency”) other than U.S. dollars and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the judgment currency for the purpose of such judgment or order, and (ii) the rate of exchange at which such indemnified person is able to purchase U.S. dollars with the amount of the judgment currency actually received by the indemnified person. The foregoing indemnity shall constitute a separate and independent obligation of the Company and the Selling Stockholder and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid.

Ladies and Gentlemen,

In reliance on Section 5(d) of the Securities Act of 1933, as amended (the “Act”), DoubleDown Interactive Co., Ltd. (the “Issuer”) hereby authorizes B. Riley Securities, Inc. (the “Sole Bookrunner”) and its affiliates and the employees of the Sole Bookrunner and its affiliates to engage on behalf of the Issuer in oral and written communications with potential investors that are “qualified institutional buyers”, as defined in Rule 144A under the Act, or institutions that are “accredited investors”, as defined in Regulation D under the Act, to determine whether such investors might have an interest in the Issuer’s contemplated initial public offering (“Testing-the-Waters Communications”). A “Written Testing-the Waters Communication” means any Testing-the-Waters Communication that is a written communication within the meaning of Rule 405 under the Act.

The Issuer represents that it is an “emerging growth company” as defined in Section 2(a)(19) of the Act (“Emerging Growth Company”) and agrees to promptly notify the Sole Bookrunner in writing if the Issuer hereafter ceases to be an Emerging Growth Company while this authorization is in effect. If at any time following the distribution of any Written Testing-the-Waters Communication there occurs an event or development as a result of which such Written Testing-the-Waters Communication included or would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances existing at that subsequent time, not misleading, the Issuer will promptly notify the Sole Bookrunner and will promptly amend or supplement, at its own expense, such Written Testing-the-Waters Communication to eliminate or correct such untrue statement or omission.

Nothing in this authorization is intended to limit or otherwise affect the ability of the Sole Bookrunner, its affiliates or the employees of the Sole Bookrunner and its affiliates to engage in communications in which they could otherwise lawfully engage in the absence of this authorization, including, without limitation, any written communication containing only one or more of the statements specified under Rule 134(a) under the Act. This authorization shall remain in effect until the Issuer has provided to the Sole Bookrunner a written notice revoking this authorization. All notices as described herein shall be sent by email to the attention of Jimmy Baker at jbaker@brileyfin.com.

Ladies and Gentlemen:

The undersigned understands that you, as Representative of the several Underwriters propose to enter into an underwriting agreement (the “Underwriting Agreement”) with DoubleDown Interactive Co., Ltd., a corporation organized under the laws of the Republic of Korea (the “Company”) and STIC Special Situation Diamond Limited, providing for the public offering (the “Public Offering”) by the several Underwriters named in Schedule 1 to the Underwriting Agreement (the “Underwriters”), of common shares, with par value of W10,000 per share, of the Company (the “Common Shares”) in the form of American Depositary Shares (the “ADSs”), each ADS representing 0.05 Common Shares (the Common Shares and the ADSs collectively, the “Securities”).

In consideration of the Underwriters’ agreement to purchase and make the Public Offering of the Securities, and for other good and valuable consideration receipt of which is hereby acknowledged, the undersigned hereby agrees that, without the prior written consent of the Representative, the undersigned will not, and will not cause any direct or indirect affiliate to, during the period beginning on the date of this letter agreement (this “Letter Agreement”) and ending at the close of business 180 calendar days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Common Shares, including in the form of ADSs, or any securities convertible into or exercisable or exchangeable for Common Shares or the ADSs (including without limitation, Common Shares, including in the form of ADSs, or such other securities which may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and securities which may be issued upon exercise of the convertible bonds and bonds with warrants) (collectively with the Common Shares and the ADSs, the “Lock-Up Securities”), (2) enter into any hedging, swap or other agreement or transaction that transfers, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Lock-Up Securities, in cash or otherwise, (3) make any demand for, or exercise any right with respect to, the registration of any Lock-Up Securities, or file, cause to be filed or cause to be confidentially submitted any registration statement in connection therewith, under the Securities Act of 1933, as amended, or (4) publicly disclose the intention to do any of the foregoing.

The undersigned further confirms that it has furnished the Representative with the details of any transaction the undersigned, or any of its affiliates, is a party to as of the date hereof, which transaction would have been restricted by this Letter Agreement if it had been entered into by the undersigned during the Restricted Period.
