Gaming machine

A gaming machine which causes a game to be played on condition that a game medium is inserted therein, and allows a player to play a special game more advantageous than a normal game when a predetermined condition is achieved according to a preset probability of occurrence, said gaming machine comprising:

• a switch for setting a set value of the preset probability of occurrence of said special game at a plurality of setting stages;
• random number generator for generating a random number within a predetermined numerical range;
• an apparatus for determining, according to a setting stage value number set by said switch for setting and a random number value generated by said random number generator, an estimation of the set value set by said switch for setting;
• and
• an indicator for informing, according to the determination made by said apparatus for determining, said player of the estimation of the set value set by said switch for setting.
