<p>PROBLEM TO BE SOLVED: To improve interest in a game by controlling the performance of a rotary drum presentation in a new mode.SOLUTION: A rotary drum presentation for temporarily stopping multiple rotating rotary drums is performed based on a fact that multiple operation parts corresponding to each one of the multiple rotary drums have been operated during a period till the termination of one time symbol variable game. Besides, re-performance lottery processing to determine whether the rotary drum presentation is to be performed again is performed. When it is determined that the rotary drum presentation is to be performed again in the re-performance lottery, the rotation of the rotary drums temporarily stopped in the rotary drum presentation is started and the rotary drum presentation is performed again. When a frequency of the re-performance of the rotary drum presentation becomes a regulated frequency, a probability to determine the re-performance of the rotary drum presentation in the re-performance lottery is allowed to change.</p> |
