Abstract: A computer-implemented method for operating a computer game. It can include identifying a playing user and one or more other users; storing user information about one or more other users and the game progress information of those other users; determining whether any of the other users satisfy a predetermined condition based on their game progress information; identifying any of the other users that meet the condition and qualify as substitution-target users; displaying the substitution-target users to the playing user; obtaining input from a playing user indicating the selection of at least one substitution-target user; allowing the user to play the game, and obtaining a result of a game played by a playing user on behalf of a substitution-target user, with said game being one available to the substitution-target user; and updating the game progress information of the substitution-target user in accordance with the result of that game.
