PROBLEM TO BE SOLVED: To prevent a valid period from being extremely extended while appropriately treating validity of ball entry in consideration of retention of a game ball.SOLUTION: (A) When a variation display of a normal symbol ends (time t1), and a winning mode continues for a certain period of time (time t2), after a lapse of wait time for opening, (B) a variable start winning device opens (time t3). (F) From the beginning of operation, winning determination is valid. (D) When a winning detecting signal is detected from a start pocket switch within an open time τ1, the signal is determined valid. (B) The variable start winning device is closed after a lapse of the open time τ1 (time t4), (F) the winning determination is valid during a close time τ2. (C) Even when the winning detecting signal is input during a valid time due to stagnation or the like, the signal can be determined valid even after the end of the close time τ2 by arranging a winning valid timer (X period). |
