PROBLEM TO BE SOLVED: To sufficiently develop the fun in the presentation of ready-for-winning modes by setting the occurrence rate of the super ready-for-winning modes or the unfortunately lost ready-for-winning modes higher than that in the normal operation during the period of a special game position such as the varying of probability. SOLUTION: A special pattern is variably displayed on special pattern display sections 43-45 of a special variable display device 40 while an advantageous special game position is generated for players when the results of display present the predetermined specific results of display. The results of display are decided before derived by the variable display sections 43-45 and when specified conditions are held, any varying pattern is selected from among multiple kinds of ready-for-winning varying patterns to control the varying at the variable display sections 43-45. At this point, differentiated reliability in reaching the specific results of display is set for the multiple kinds of ready-for-winning mode varying patterns. During the period of a special game position, the occurrence rate of the failure in reaching the specific results of display (lost case) in the ready-for-winning mode varying patterns with a higher reliability in the normal operation is set higher as compared to that in the normal operation. |
