PROBLEM TO BE SOLVED: To prevent decision on whether control is performed to an advantageous state from being performed by using numerical data extracted at different timing.SOLUTION: A random number is fetched into a random number value register from a random number generation circuit regardless of whether start conditions are satisfied based on start winning of a game ball, and the random number value fetched into the random number value register is read out and is reserved and stored in satisfaction of start conditions including a condition that a holding storage number does not reach an upper-limit number. When a special pattern game is completed while the holding storage number has reached the upper-limit value and then a new special pattern game is started and when power is turned on and reset, a random number value fetched into the random number value register is read out and is abandoned without any holding storage. Fetching of a new random number by the random number value register is limited until the fetched random number value is read out. When power is turned on, updating of a random number by a random number generation circuit is limited for a random period.SELECTED DRAWING: Figure 13 |
