PROBLEM TO BE SOLVED: To provide a game machine capable of enhancing amusement by using presentation symbols.SOLUTION: The game machine includes, as types of decorative symbols, blue symbols, green symbols, red symbols, and gold symbols. The game machine determines whether or not a big win (jackpot) is won on the basis of a winning entrance of a game ball to a start port, and if determined as the big win, determines whether the big win is either a normal big win or a privileged big win that is more advantageous to a player than the normal big win. On the basis of a prior determination result, if the red symbols are stopped in a specific mode, the big win game is more likely to be performed after that than if the blue symbols are stopped in a specific mode. Also, if the red symbols are stopped in a big win mode, a possibility of being the privileged big win is higher than if the blue symbols are stopped in the big win mode. Also, the gold symbols have a highest expectation degree when a ready-to-win presentation is performed and has a highest expectation degree for the privileged big win.SELECTED DRAWING: Figure 24 |
