PROBLEM TO BE SOLVED: To provide a game machine improving efficiency of opening of large winning holes, while retaining appropriate opening/closing of the large winning holes.SOLUTION: A large winning hole 91 and a second large winning hole 92 are vertically disposed in a game area 52. A winning detection device 78 and a winning detection device 79 detect discharge of game balls from the large winning hole 91 and the second large winning hole 92 until a prescribed residual discharge detection period elapses. Special game control means alternately opens the large winning holes in such a form as to, after one large winning hole is closed, start opening the other large winning hole, before the residual discharge detection period of the one large winning hole elapses. Further, lengths of a minute standby period, an opening time of the large winning holes, and the residual discharge detection period are designed respectively such that, after the one large opening hole is closed, the one large winning hole is opened next on and after the lapse time of the residual discharge detection period.SELECTED DRAWING: Figure 1 |
