When a combination of main symbols on which a same numeral is drawn is finally stationarily displayed, the game is transferred to an opening/closing execution mode. When a result is a first jackpot, after the opening/closing execution mode ends, the game is transferred to a 80-time first low-probability time-shortened game state, when the result is a second jackpot, after the opening/closing execution mode ends, the game is transferred to a 40-time second low-probability time-shortened game state, when the result is a third jackpot, after the end of the opening/closing execution game, the game is transferred to a 20-time low-probability time-shortened game state. In those low-probability time-shortened states, the promising number of special ready-to-wins produced till the corresponding game state ends is made equal and an expectation degree of the jackpot in a special ready-to-win is also made equal. |
