Title: Game machine
Inventor: BANZAWA MASAHISA
IPC: A63F7/02
Filed: 2018-06-27
Abstract: To enhance a performance effect after a special game and to enhance game amusement.SOLUTION: A prescribed period after a jackpot game is performance mode C which corresponds to both a low-probability high-base state and a high-probability high-base state. By passage of the prescribed period, the performance mode C can be switched to performance mode D corresponding to a low-probability high-base state or performance mode E corresponding to the high-probability high-base state. By doing so, performance modes change before and after the prescribed period passes after the jackpot game, and a performance content changes accordingly. By shifting the performance mode C to the performance mode D or E, a real game is shown to a player. Thus, it is possible to attract a player's interest to the performance content (switching of performance modes) after the jackpot game and to enhance game amusement.SELECTED DRAWING: Figure 46
