Riverboat Hold'em is a poker-derived casino table game that can be found in Indiana and Mississippi riverboat casinos. It uses a standard 52-card deck, and a round begins with the player placing an ante and having the option of making a river bet too.
The dealer then deals himself or herself two face-down cards and also gives each player two cards face-down. After looking at his or her cards, each player chooses from among three actions: Fold (forfeit the ante, but river bets stay active), Call (place an additional sum at risk equal to the ante), Raise (place an additional sum at risk equal to two times the ante).
Then the dealer places three community cards face-up on the table. The dealer's hand is then checked to see if it qualifies by being king-jack high or higher.
If the dealer fails to qualify, then all ante bets pay out 1:1 while and call and raise bets push. If the dealer qualifies and a player beats the dealer hand, then all ante, call, and raise bets pay off at 1:1. If the dealer qualifies and wins or ties a player's hand, then the dealer collects all ante, call, and raise bets from that participant.
The river bet pays out solely based upon the strength of a player's hand. According to the pay table most commonly used in Indiana, the river bet pays off at 1:1 on a pair of sixes of better with higher payoffs for stronger hands until we reach a royal flush, which pays 500-1.
