Title: Game machine
Inventor: TAMURA JUNICHI
IPC: A63F7/02
Filed: 2018-06-28
Abstract: To provide a game machine appropriately detecting an occurrence of a fraudulent winning.SOLUTION: When entry of a game ball in a prescribed entry hole is detected, a pachinko machine adds a count value of a base abnormality counter and, when discharge of game balls from a game area is detected, subtracts the count value of the base abnormality counter. When the count value of the base abnormality counter reaches a prescribed determination value, an occurrence of a base abnormality error is determined. Especially, a variable ball entry hole is excluded from the ball entry holes as monitoring objects of the base abnormality error. This configuration can prevent, regardless of not occurring a fraudulent winning, an occurrence of a base abnormality error from being determined, caused by such an event that a ball entry frequency in the variable ball entry hole increases during a period when the variable ball entry hole is opened.SELECTED DRAWING: Figure 35
