Roulette Gaming Machine Changing Payout Ratio Set For Specific Bet Type And Playing Method Of Roulette Game

Abstract

In a unit game that is repeatedly executed, an “ODDS UP determining process” is executed in which a bet type to be subjected to ODDS UP is randomly determined, among all bet types. When the “ODDS UP determining process” is executed, one or more bet types are determined as a specific bet type, or no bet type is determined as a specific bet type. When there is a specific bet type determined in the “ODDS UP determining process,” a payout ratio set for the specific bet type is switched from a base ratio to a specific ratio higher than the base ratio. Thereby, when a bet is made in the specific bet type determined in the “ODDS UP determining process” and a winning is made in this bet type, a payout to be awarded to a player is larger.

1 . A roulette gaming machine comprising:
