To carry out an interesting performance in each display region without imposing a burden on a main control part when a symbol variation game is carried out in each display region by forming a plurality of display regions by dividing a display region in a display device.
When a divided performance in which the symbol variation game is performed in each display region D1-D4 after dividing the display region D into a plurality of the display regions D1-D4 is performed, the control of the divided performance is carried out by a sub-control board and a performance display control board which replace the main control board. The sub-control board is configured to increase a probability to determine the number of second display regions to be large for leading out the same ready-to-win symbol as the ready-to-win symbol led in a first display region in a case of winning a prize in a jackpot lottery and carrying out the divided performance, compared to a case of not winning a prize in the jackpot lottery.
