PROBLEM TO BE SOLVED: To make a player easily interested in a special symbol jackpot game provided in a game machine in which a special symbol is drawn once by activation of an ordinary electric accessory.SOLUTION: When a player enters a ball into an ordinary electric accessory that has been opened by winning a normal symbol (B5, B6) and then enters a ball into a start port of a special symbol (G4), the special symbol almost always results in a jackpot and a condition device is activated (I3). When a special electric accessory starts operating (J5) and a player promptly enters a ball into a jackpot port 25 that is opened twice (K5, K7), there is a time zone in which the condition device does not operate and the ordinary electric accessory is under operation. If a ball enters the start port of the special symbol during the time zone (G5), the special symbol is varied (H7) and there is a chance to win a jackpot again. It is thus possible to obtain a chance by prompt entry of a game ball into the opened jackpot port 25, thereby making a player interested in a special symbol game that has been used to the extent of changing probability of the normal symbol. |
