Filed: 2019-10-25
Abstract: To enhance an interest in a game in a game machine capable of executing a second-class winning game.SOLUTION: Since a second-class game A may be performed after a small win game when a first-class winning game A is performed in a game machine, a degree of advantage to a player differs mutually in these cases. When a performance of the game machine is changed, execution probability of the second-class winning game is not changed but execution probability of the first-class winning game is changed. For this reason, simply by changing the performance of the game machine, a ratio of "probability of execution of the first-class winning game A" to "probability of execution of the second-class winning game A" can be changed. As a result, game properties of the game machine can be further diversified.SELECTED DRAWING: Figure 23
