A casino game incorporates at least a first compulsory playing mode and one or more optional playing modes without a house advantage. Preferably, the first playing mode is a three-, five- or seven-card poker game against a payout scale based on the respective hand poker rank or against both a payout scale and the dealer. Optional modes without a house advantage include head-to-head poker games against the dealer only and poker games against other players. Side wager options are also available for high hands, thereby increasing player interest by providing a chance for a high payout.
