  • Patent number: 8162747
    Abstract: A game control program is provided to improve user convenience of a game. A game control unit executes a game program, and records a history into a history holding unit while controlling progress of the game. When an operation instruction to pause the game is accepted from the user, a pause control unit stops the progress of the game with the display screen at that point in time displayed. When a request to resume the game is accepted from the user, a resume control unit resumes the game after display screens and sound are reproduced from a point in time which is a predetermined period before the pausing point up to the pausing point.
