PROBLEM TO BE SOLVED: To precisely grasp that a so-called irregular shot is performed in a slot machine through no manpower. SOLUTION: When a game start operation and the operation of three stop buttons are performed in the slot machine 1, three kinds of stop signals capable of specifying reels to be stopped according to the operations are imparted to a management device 4 in the state having a time difference. In the management device 4, the stopping order of three reels is judged on the basis of the output order of the three kinds of stop signals, and it is judged whether the stop order of each reel corresponds to the irregular shot or not on the basis of the comparison result of the stop order with a preliminarily stored stop order set table. When the thus-judged state is performed continuously a prescribed number of times (five times) or more, an alarm signal is outputted.
