  • Patent number: 8282104
    Abstract: The reduction in real operation objects in game systems that use real operation objects is detected. The quantity of real operation objects, which are repeatedly used by being circulated, is detected, it is judged whether the quantity is sufficient or not, and the judging results are output. For example, in a ball throwing game, balls are used in rotation by repeatedly supplying and recovering the balls. The quantity of balls in circulation is detected, and if the quantity is less than a threshold value, the manager of the game system is notified whether a sufficient quantity of balls is being supplied to the player or not, by for example outputting a warning message. By playing with an insufficient quantity of balls the level of difficulty of the game is essentially increased, so the player will feel that this is unfair.
