GAME MACHINE

PROBLEM TO BE SOLVED: To improve game spirit during a shift period to an RT mode.SOLUTION: A slot machine includes a counter and a state control unit. The counter stores an initial value (for example, "0") until a watermelon wins, and sets a reference value (for example "100") when the watermelon wins. After this, a subtraction value (for example, "1") is subtracted from a counter value in each game. The state control unit enables the slot machine to shift to an permission condition for allowing shift to the RT mode when a bell wins, and cancels the permissible condition when a cherry wins, or the RT mode ends. Then, the slot machine shifts to the RT mode when keeping a counter value not less than "1", and when remaining in an allowable condition. The RT mode ends when a game is executed by the amount of a value stored in the counter.
