An online game is provided to players where players may participate in individual episodes of the online racing game. The individual episodes may include individual races within the racing game in which players control game entities through racecourses. User accounts comprising an indication of game entities associated with the players of the online game, an indication of a status of the player, and a game play metric associated with the player may be managed. Races in the online game may be synthesized by simulating participation by game entities of a player in individual synthetic episodes of the online game while the player is absent from the online game. A change in the game play metric of the player may be determined based on the performance of the first game entity in the race of the first synthetic episode.
