PROBLEM TO BE SOLVED: To properly process a medal acquiring number for a player during a big bonus which is generated following the completion of a challenge time. SOLUTION: A slot machine performs the lottery for the challenge time when the big bonus ends, and when the challenge time is elected, the challenge time is generated following the big bonus. At this time, during the challenge time, the lottery of the big bonus is performed, and when the big bonus is elected, a slide control is performed for reels so that a big bonus pattern may arranged. In this case, when a player is an expert, the big bonus is generated by a less game number of times from the end of the challenge time. Therefore, when a BB signal is input within a set game number of times since the input of a CT (challenge time) signal following the BB (big bonus) signal from the slot machine stops, an acquisition number-counting period is extended until the BB signal ends.
