<P>PROBLEM TO BE SOLVED: To prevent a fraudulent act with respect to a variable prize winning device. <P>SOLUTION: The state of the variable prize winning device is controlled by a common processing routine in a first specified game state and also in a second specified game state, based on data indicating a game progress state. It is determined whether abnormal winning occurs based on the output of a winning detection signal by a prize winning detection unit. An abnormality report indicating the occurrence of the abnormal winning is issued based on the determination that the abnormal winning occurs. Besides, when the data indicating the game progress state is a numerical value being a prescribed value, the variable prize winning device is controlled to be an open state. When the data indicating the game progress state is a numerical value equal to or more than the prescribed value, processing to determine whether the abnormal prize winning occurs is not performed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
