PROBLEM TO BE SOLVED: To provide a pinball game machine capable of limiting a condition, by which the drive speed of a discharge device is decelerated, in situations that undischarged prize balls are discharged, and repeating high-speed discharge, thereby completing the discharge of a large amount of undischarged prize balls in a shorter time than a conventional machine.SOLUTION: The pinball game machine includes a undischarge counter and a discharge counter where a total value is the number of undischarged prize balls stored by a game machine. Under the condition that a value of the undischarge counter is "0" and a value of the discharge counter is "1", drive speed of the discharge device is lowered. Moreover, a surplus ball counter is provided, operation is performed by a value of the surplus ball counter and a value of the discharge counter, and the number of surplus balls is subtracted from the number of undischarged prize balls. |
