PROBLEM TO BE SOLVED: To provide a game machine and its performance method capable of preventing a game from becoming monotonous. SOLUTION: Either a first fluctuating pattern group or a second fluctuating pattern group is selected using a random number counter counting in a predetermined counting period by means of a main control board 120, and a predetermined fluctuating pattern is determined out of the selected fluctuating pattern. A game circumstance is changed by means of a sub control board 124 based on the fluctuating pattern determined by means of the main control board 120. Consequently, the fluctuating pattern can be changed by properly changing the combination of a special performance mode and a normal performance mode without changing the generation ratio (proportion)of the special performance mode. As the result, the game can be prevented from becoming monotonous. COPYRIGHT: (C)2007,JPO&INPIT
