Filed: 2020-05-15
Abstract: To enhance game amusement in a game machine where an electrically supported state can be set.SOLUTION: In the game machine, an electrically supported state is set (instead of a non-electrically-supported state) when "the frequency of being trapped" reaches a regulated frequency, the regulated frequency in this case being a frequency corresponding to "an execution frequency of a jackpot game in a predetermined period". Namely, when "the frequency of being trapped" reaches a frequency (regulated frequency) corresponding to "an execution frequency of a jackpot game in a predetermined period", an electrically supported state is set (instead of a non-electrically-supported state). Consequently, for a player expecting an electrically supported state to be set sooner (with less frequency of being trapped), novel game property of making the player to pay attention to "an execution frequency of a jackpot game in a predetermined period" is realized, which enhances game amusement.SELECTED DRAWING: Figure 23
