The first special symbol display means 83 is composed of a seven-segment type display means capable of variably displaying the first special symbol. When the special symbols are displayed variably for a predetermined period of time and the jackpot determination random value included in the first special random number information acquired when the first special symbol starting means 62 detects the game ball matches the predetermined jackpot determination value. In other cases, the variation is stopped in the first jackpot mode. When the stopped symbols after the change of the first special symbol display means 83 become the first jackpot mode, a first special profit state occurs.

The second special symbol display means 84 is constituted by a display means such as a 7-segment type display means capable of variably displaying the second special symbol. When the special symbols are displayed in a variable manner for a predetermined period of time and the jackpot determination random number included in the second special random number information acquired when the second special symbol starting means 63 detects the game ball matches a predetermined jackpot determination value. In other cases, the fluctuation is stopped in the second jackpot mode. When the stopped symbol after the change of the second special symbol display means 84 becomes a second jackpot mode, a second special profit state occurs.

In addition, the first and second special symbols are activated during the special suspension period, including during the symbol fluctuation of the first special symbol display means 83, during the symbol fluctuation of the second special symbol display means 84, and during the first and second special profit states. When the means 62 and 63 detect game balls, the first and second special random number information obtained thereby are stored with a predetermined upper limit of the number of balls held, for example, 4 balls each. When the special reservation period ends, if the reservation memory on the second special symbol side is 1 or more, one reservation memory of the second special symbol is consumed, the second special symbol is changed, and the second special symbol is changed. When only the reserved memory on the special symbol side is 1 or more, one reserved memory of the first special symbol is consumed to change the first special symbol. In this way, in this embodiment, both the first special symbol and the second special symbol do not change, and when there is a pending memory on both the first special symbol side and the second special symbol side, is designed to preferentially change the second special symbol. The stored numbers of the first and second special random number information (the first and second special reserved numbers) are notified to the player by the liquid crystal display means 66 or the like.
