PROBLEM TO BE SOLVED: To prevent determination of whether the play should be controlled in a specific game state or not by using a numerical value extracted at different timing than the timing when a starting condition is effectively established. SOLUTION: The state of an electric tulip-type generator which forms a second starting winning hole is changed to an opened state in which game balls can enter for only a fixed period if a normal symbol game is won. When a game ball detection signal is output from a switch disposed in the second starting winning hole, a random number is taken into a random number register disposed in each starting winning hole regardless of whether the starting condition is established or not based on the entrance. At the time, if the starting condition is established, the random number taken into the random number register is read to be used for a jackpot lottery. If the detection signal is output from the switch disposed in the second starting winning hole while the electric tulip-type generator is closed, the random number taken into the random number register is read to be canceled without being used for the jackpot lottery.
