PROBLEM TO BE SOLVED: To stop a game even if data stored in an IC card is normal data.SOLUTION: A main control device 40 subtracts the total number of dispensing balls from the current number of own balls to calculate a difference in S810, and determines whether the difference has reached an upper-limit value. In updating processing, data on the number of own balls is outputted to a CR unit 60 as it is and then is forced to be cleared to zero. When the data on the number of owned balls inputted from the CR unit 60 is stop of shooting or a flag of an exchange pattern is stored, a game ball cannot be shot even if the data is normal. Thus, when a game is completed by the shooting-stop or the exchange pattern, prize exchange is required. |
