PROBLEM TO BE SOLVED: To make it impossible or hard to discriminate actuation/non-actuation of a probability variation function during a jackpot game in a pinball game machine including a first large winning hole and a second large winning hole having a probability variable hole. ! SOLUTION: During a jackpot game, in a round where a second large winning hole is opened, a Pachinko machine opens a probability variable hole when a wait period elapses from a start of the round and then, when a game ball entering the second large winning hole enters the probability variable hole, transfers a game state to a probability variable state after the jackpot game. Further, the Pachinko machine includes types A-C as the jackpot games and, in a period across X and X+1R of each type of jackpot games, opens/closes the second large winning hole in a same mode, so that it is difficult to discriminate the type from behavior of the second large winning hole. Furthermore, in the types A and B, one of the X and X+1R continues l |
