PROBLEM TO BE SOLVED: To provide a slot machine capable of efficiently executing a process when selecting a control pattern of a variable display device and a process when determining an abnormal winning. SOLUTION: CPU 41a sets a winning number uniquely assigned to the result of an internal lottery and selects stop control data specified from index data stored in a storage area corresponding to an address of an index area calculated from the winning number, as stop control data of the game. When a value of a bit assigned for every type of a role based on the winning number is 0, this slot machine indicates to permit the winning of the role and, when the value is 1, creates an abnormal winning determination flag indicating not to permit the winning of the role. When determining the abnormal winning or not, this slot machine logically multiplies the abnormal winning determination flag and a winning symbol flag which indicates the winning of the role when the value of the bit assigned for every type of a role is 1 and indicates non-winning of the role when the value is 1, and determines based on whether the operation result is 0 or 1.
