Patent ID: 7601064

Claim:
A game apparatus comprising: a connection unit that is communicably connected to a controller which has a lever that is guided along a predetermined route, and which sends status information specifying a current position of the lever and receives instruction information specifying a repulsive force to be applied to the lever; a storage unit that pre-stores repulsive force information specifying a repulsive force to be applied to a lever, in association with a game status and a position of a lever; a reception unit that receives status information from said controller via said connection unit; a generation unit that acquires the repulsive force information pre-stored in association with a current game status and a position of a lever specified by the received status information, and generates instruction information specifying a repulsive force specified by the acquired repulsive force information; and a sending unit that sends the instruction information generated by said generation unit to said controller via said connection unit, and wherein, the generation unit generates a random number and designates as the instruction information, a value obtained by heightening or lowering the repulsive force specified by the acquired repulsive force information with the generated random number, at every predefined interval.
