And (3) determining the symbol variation time. A) In the stop symbol determination process, if the random number for jackpot determination in the current determination area is a jackpot value, a stop symbol is determined from the random number for jackpot symbol selection in the current determination area. If the random number for jackpot determination in the current determination area is an outlier, a left stop symbol random number for escape, a medium stop symbol random number for miss, and a right stop symbol random number for miss are extracted, and left, middle and right stop symbols are determined. However, in the case of left symbol = middle symbol = right symbol, the right symbol is set to +1 and a stop symbol is determined. B) In the symbol variation time determination processing, the variation time of the left symbol and the middle symbol is fixed time. In addition, in the case of the big hit and the left symbol = the middle symbol reach state, the fluctuation time of the right symbol is extracted from the reach time determination random number value, and in the case of the deviation, the fluctuation time of the right symbol is the same as the left symbol and the middle symbol. Fixed time. Then, after the processing is completed, the job counter is counted up. Job 2: Shows special symbol stop processing, left symbol, middle symbol,
The right symbol is sequentially varied, and after the variation time of each symbol elapses, the left symbol, the middle symbol, and the right symbol are sequentially stopped, and after the processing is completed, the job counter is counted up. Job 3: Indicates a jackpot determination process. If the random number for jackpot determination in the current determination area is the jackpot value, the job counter is counted up. In the case of an outlier, the job counter is cleared after a certain time (symbol stop time) has elapsed. Job 4: Indicates a jackpot start process, and performs the following jackpot start processes a) to d). A) Set a special winning opening time. B) Set 1 to the special winning opening counter. C) Clear the 10-count winning counter. D) Clear the special winning opening V switch passing flag and count up the job counter after a certain time (big hit start waiting time) has elapsed.
