To provide a game machine capable of simplifying control, etc.

An upper start winning port 33A, a lower start winning port 33B, a variable winning device 32, and a through-gate 34, etc. are arranged on a game board 30 of a pachinko game machine. When a game ball shot toward the game board 30 enters the start winning ports 33A, 33B, jackpot lottery is performed on whether a jackpot state is to be generated or not. When a jackpot is generated, the variable winning device 32 is opened to acquire a large amount of prize balls. The pachinko game machine includes: a lottery mode flag for discriminating whether a lottery mode is a high-probability mode or a low-probability mode; and a support mode flag for discriminating whether a winning support mode is a high-support mode or a low-support mode. Then, an additional value obtained by adding both of the flag values is acquired as a game state determination value. The determination of a variable pattern table, etc. is performed based on a game state determination value.
