<p>PROBLEM TO BE SOLVED: To provide a game machine with excellent fraud prevention measures that can inhibit game media from being put out to a putout request for game media that have not been actually put therein.SOLUTION: The game machine includes three feeding devices. A fraud causing the game machine to count game balls that have not been actually put therein, as put-in game balls, is hard to simultaneously execute for all feeding devices, and it is prone to be executed on any one of the feeding devices. Therefore, the game machine compares ratios of the number of game balls incorporated in the respective feeding devices and, when there is a large difference among the respective ratios of the game balls, prohibits putout of game balls. Consequently, when there is a possibility that the fraud has been executed, the game machine can prohibit the putout of game balls.</p> |
