Filed: 2020-08-27
Abstract: To provide a game machine which can suppress the interest in a game.SOLUTION: When a specific ready-to-win by a first drawing pattern turns out, a jackpot expectation degree is higher than that in a case in which a normal ready-to-win by a second drawing pattern turns out. A performance display device can execute a specific performance, and whether or not the specific performance can be executed is determined on the basis of a prior determination result of a variation content. The specific performance can be executed in an execution period of a variation game executed before a last variation game. A probability of a specific ready-to-win turning out in the last variation game is tha same in a case in which a power interruption occurs and the specific performance ends in the middle and in a case in which no power interruption occurs and the specific performance does not end in the middle. A ratio calculated by dividing the number of the first drawing patterns by the number of all drawing patterns is different from the probability of the specific ready-to-win turning out in the last variation game. When a power interruption occurs and the specific performance ends in the middle, a probability of a first stop state turning out is different between in the last variation game and in a variation game before the last variation game.SELECTED DRAWING: Figure 10
