<P>PROBLEM TO BE SOLVED: To make a player win a heaven mode with a comfortable sense of accomplishment. <P>SOLUTION: Jackpot types of a first or a second special symbol lottery include a specific jackpot. In the specific jackpot, a heaven chance of a high probability time shortening period is started after a jackpot game based on the winning of the jackpot during a normal mode of a low probability non-time shortening period. The time shortening period continues after demoting from a high probability to a low probability and a mode consecutively moves to a heaven mode of a low probability time shortening period by providing predetermined conditions such as ST-through. During the heaven chance of the high probability time shortening period, the rate of demoting to the normal mode of the low probability non-time shortening period based on a jackpot of the second special symbol lottery is higher than the rate of demoting to the normal mode of the low probability non-time shortening period based on a jackpot of the first special symbol lottery. Thus, original right-handed shooting is suppressed for a while, and the right-handed shooting is resumed after moving to the heaven mode so that the update of the heaven mode is repeated. By this, a predetermined number of balls obtained in each jackpot game can be obtained two or more times. <P>COPYRIGHT: (C)2013,JPO&INPIT |
