PROBLEM TO BE SOLVED: To provide a device for games capable of accurately acquiring the number of difference from a previous advantageous state such as ART to a current advantageous state without using an optical sensor that has a possibility of being regarded as a fraudulent remodeling.SOLUTION: The device for games calculates the number of cumulative difference between the number of cumulative putout game media that is the total number of game media put out from a game machine, and the number of cumulative used game media that is the total number of game media used in the game machine on the basis of a number-of-used game media signal and a number-of-putout game media signal. When receiving a game state transfer signal, the device for games calculates the number (&bgr;1-α1) of difference between the current number (&bgr;1) of cumulative difference stored corresponding to the current game state transfer signal and the previous number (α1) of cumulative difference stored when receiving a previous game state transfer signal, as the number of difference between game states. |
