PROBLEM TO BE SOLVED: To provide a slot machine using game balls which can efficiently perform processing in selecting the control pattern of a variable display device and processing in determining abnormal winning. SOLUTION: A CPU 41a sets a winning number uniquely assigned to the result of internal lottery and selects data for stop control which is specified by an address to be calculated based on the above winning number. A flag for determining the abnormal winning is generated, which indicates that winning in a role is permitted when a bit assigned for each role kind is zero and that the winning in the role is not permitted when a bit is one, based on the winning number. When whether the abnormal winning or not is determined, a logical AND operation is performed on the flag for determining the abnormal winning and a winning pattern flag which indicates that the role is won when the bit assigned for each role kind is one and that the role is not won when the bit is one. Determination is performed based on whether the logical AND operation result is zero or not. COPYRIGHT: (C)2008,JPO&INPIT
