PROBLEM TO BE SOLVED: To improve a game property by varying the state of a game corresponding to a power amount that an operation means receives. SOLUTION: When the game of an AT mode is started, a reference pressure is set. After the game progresses and a pressure received in an operation direction after a stop button operated at the end of the game is operated to be at an input position is measured, a difference between the maximum value of the measured pressure and the reference pressure is deduced, and by random number drawing using a probability table corresponding to the difference, whether or not to drive a sub reel 15 in the case that a bell is won in the next game is decided. When the sub reel 15 is driven, the operation order of the stop buttons 19a-19c enabling the winning of the bell is indicated. COPYRIGHT: (C)2005,JPO&NCIPI
