DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No.  1 relates to the Registration Statement on Form S-8 (Registration No. 333-161727) filed by Changyou.com Limited, a Cayman Islands company (the “Registrant”), on September 4, 2009 (the “Registration Statement”) under the Securities Act of 1933. The Registration Statement registered 20,000,000 Class A ordinary shares, par value $0.01 per share, of the Registrant for issuance under the Changyou.com Limited 2008 Share Incentive Plan.

On April 17, 2020, the Registrant completed the merger contemplated by the Agreement and Plan of Merger, dated January 24, 2020 (the “Merger Agreement”), among the Registrant; Sohu.com (Game) Limited, a Cayman Islands company (“Sohu Game”) and an indirect wholly owned subsidiary of Sohu.com Limited, a Cayman Islands company (“Sohu.com”); and Changyou Merger Co. Limited, a Cayman Islands company and a direct wholly owned subsidiary of Sohu Game (“Merger Co.”). Pursuant to the Merger Agreement, Merger Co. was merged with and into the Registrant (the “Merger”), with the Registrant surviving the Merger as a direct and indirect wholly-owned subsidiary of Sohu.com.

As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statement. The Registrant is filing this Post-Effective Amendment No. 1 to the Registration Statement to remove from registration all securities registered under the Registration Statement that remain unsold as of the date hereof.
