PROBLEM TO BE SOLVED: To prevent a player from being bored by making the player enjoy the play.SOLUTION: When a variable probability reduced time jackpot is won, the game state in a game machine becomes a first variable probability game state 312b in a prescribed period after the jackpot game, and a presentation is executed in a latent presentation mode 322. The period of the first variable probability game state 312b differs according to kinds of the won variable probability reduced time jackpots (first - fifth variable probability reduced time jackpots) generating the first variable probability game state 312b. If jackpot lotteries are executed a prescribed number of times in the first variable probability game state 312b, the game state in the game machine 100 is changed to a second variable probability game state 313, and a presentation is executed in a variable probability presentation mode 323. The second variable probability game state 313 is a game state set so that the variation time of special symbols is relatively shorter than in the first variable probability game state 312b. In the second variable probability game state 313, a game with game efficiency higher than in the first variable probability game state 312b can be played. |
