PROBLEM TO BE SOLVED: To reduce the increase of stress of a player and to enhance the seasoning of a game in a game machine in which game state can not be discriminated.SOLUTION: A first start area and a second start area are provided in a game area, and when a game ball enters the start areas, drawing of a big winning is performed. The second start area is variably controlled to a first form wherein a game ball does not easily enter and a second form wherein the game ball easily enters. The game is advanced in a low probability game state wherein the winning probability of the big winning is low, and a high probability game state wherein the winning probability of the big winning is high. While the game is advanced, a performance is executed in two or more kinds of performance stages in which it is unknown which of the high probability game state and the low probability game is set. While the performance stage is changed by drawing, the switching and determining probability of the performance stage is different between the low probability game state and the high probability game state. When the predetermined number of second holding is consumed, the difference of the switching and determining probability of the performance stage is increased. |
