PROBLEM TO BE SOLVED: To avoid a player's motivation for a game from becoming low.SOLUTION: A rush mode sets the number of continuation of a time shortening state to 100. In the rush mode, as game balls enter a second start pocket, probability that a small winning game is played in an advantageous open pattern is high. A chance mode sets the number of continuation of the time shortening state to 15. In the chance mode, as game balls enter the second start pocket, probability that a small winning game is played in an advantageous open pattern is low but exists. The respective chance mode and the rush mode are modes to be selected when a game is determined to be a kind of jackpot. Thus, since the chance mode is set when the game is determined to be a kind of jackpot, lowering of motivation for the game when the rush mode is not set is avoidable. |
