To provide a game machine which enables a wide variety of performance of movable members without increasing a cost of development or the like while the game machine sets a movement starting position of the movable member in an optional position and prevents interference between the movable member and the other members other than the movable members.

The game machine equipped with the movable members 202, 204 performing prescribed movements as a performance on a game and a movement control means for controlling the movements of the movable members is further equipped with an interference determining means for determining whether the movement of the movable member controlled by the movement control means interferes with the other member or not. When the movement of the movable member is determined not to interfere with the other member, the movement control means controls the movable member in actual movement processing for actually moving the movable member. When the movement of the movable member is determined to interfere with the other member, the movement control means controls the movable member in virtual movement processing for virtually moving the movable member in a virtual space without actually moving the movable member.
