IPC: A63F7/02
Filed: 2019-03-12
Abstract: To improve amusement of games by achieving new game properties.SOLUTION: In a special symbol 2 preferential variation machine, during a first specific game state in a right shooting state, a second start port 21 opens in a mode difficult for game balls to enter. Therefore, a ball entrance frequency of game balls to a third start port 25 becomes higher than the frequency to the second start port 21. Consequently, variable displays of a special symbol 1 that is not the target of a preferential variation are mainly performed. On the contrary, during a second specific game state in the right shooting state, the second start port 21 opens in a mode easy for game balls to enter. Therefore, a ball entrance frequency of game balls to the second start port 21 becomes higher than the frequency to the third start port 25. Consequently, variable displays of a special symbol 2 that is the target of the preferential variation are mainly performed. As described, despite in the same right shooting state, a state in which the variable displays of the special symbol 1 that is not the target of the preferential variation are mainly performed and a state in which the variable displays of the special symbol 2 that is the target of the preferential variation are mainly performed can be set. In this way, new game properties never existed before become possible to be achieved.SELECTED DRAWING: Figure 3
