An event generation unit (203) causes game device to generate a verification event for verifying a player's manual operation based on the progress state of a game on the game device. A judgment unit (204) judges whether the manual operation is performed or not based on operation information on the terminal during the verification event. A game situation update unit (205) properly updates a game situation on the terminal based on the judgment result from the judgment unit (204).
