PROBLEM TO BE SOLVED: To provide a game machine capable of suitably detecting abnormal ball entry frequency to a ball entry device.SOLUTION: In winning frequency abnormality error processing executed by a sub-control part, 9 pieces of past winning information RAM (ring buffer), a normal winning counter, and an abnormal winning counter are prepared, and a remaining time counter (reference time) is set to 9 pieces of winning information RAM as a setting destination in reception of a normal winning device winning command and is counted down. After that, at a point of time when a 10-th normal winning device winning command is received, a normal winning counter is counted up by 1 when a winning information RAM remaining time counter on the setting destination side is 0. When the counter is not 0, the abnormal winning counter is counted up by 1, and the abnormal winning counter is counted down by 1 when the normal winning counter reaches 10. Then, a winning frequency abnormality error is determined and reported when the abnormal winning counter reaches 5.SELECTED DRAWING: Figure 67 |
