PROBLEM TO BE SOLVED: To improve the visual confirmability and interest by displaying the generation probability of big hit on a display screen when a next-to-win state where specified patterns are displayed on other elements except one of a prescribed number of display elements on an effective line is generated. SOLUTION: When a pachinko ball gets in a starting prize port, a pattern game is stated, and a big hit state where three specified patterns are arranged on each row-directional, column-directional, oblique effective line is generable on a display screen 40. At this time, the generation probability of big hit is calculated in a game processing part 31. The generation probability is increased stepwise according to the continuous frequency when the big hit is not continuously generated in the pattern game. When a pachinko ball gets in a starting prize port 12, a random number generation part 33 generates a random number is generated from a random number generation part 33, a pattern random number is generated on the basis of this random number, and the image information concerning the pattern random number is outputted to the display screen 40. When a next-to-win state display random number is generated, a bar-like index pattern is displayed on the display screen 40 to make a player infer the generation probability of big hit. |
