Abstract: To set a bet number according to an intention of a player, there is provided one bet switch 12 for a player to designate a desired bet number N. A game machine is provided in its body with a control unit 23 for setting the bet number N designated by the player by detecting whether or not the bet switch 12 has been operated. This control unit 23 sets the bet number N to a maximum allowable bet number “Kmax” when the bet switch 12 is operated one time prior to the start of each game. After this, each time the bet switch 12 is operated, the maximum allowable bet number “Kmax” is subtracted by 1, and this difference is set as the bet number N. Each time the operation number of the bet switch 12 reaches a predetermined value, the maximum allowable bet number is again set to “Kmax”. By repeating the subtraction of the bet number N by 1 each time the bet switch 12 is operated, moreover, the bet number N is set within a range of the maximum allowable bet number “Kmax”.

Abstract: In order to provide a more interesting game machine without hindering the concentration of a player in a game, the invention relates to a game machine in which the prize patterns are decided by combinations of symbols. A regular status associated with the likelihood that an appointed prize pattern may occur is indicated by a first set of one or more combinations of symbols. A status change is being indicated by one or more combinations of symbols that are different from those one or more combinations of symbols included in the first set associated with the regular status.
