Filed: 2020-04-23
Abstract: To enhance interest in a game in a game machine capable of setting an electric-tulip supported state.SOLUTION: In a game machine, when an "electric-tulip supported pattern" is stopped and displayed in a first variation or a second variation, an electric-tulip supported state is set without going through a jackpot game. A probability of stopping of such an "electric-tulip supported pattern" is higher when a second variation is performed than when a first variation is performed. For this reason, in a non-electric-tulip supported state, novel game properties of allowing one to expect execution of stopping and displaying of "an electric-tulip supported pattern" to a player (setting of an electric-tulip supported state without going through a jackpot game), and eventually "a second variation having a high stop display probability of an electric-tulip supported pattern" rather than "a first variation having a low stop display probability of an electric-tulip supported pattern" can be realized, thus enhancing interest in a game.SELECTED DRAWING: Figure 10
