Caribbean Stud is a poker game played against a dealer. Each player, including the dealer gets dealt 5 cards. The dealer places 1 card face up. You then get the chance to bet or fold. The dealer needs to have a minimm hand of AK to qualify to play. If you bet and he doesnt qualify you get paid 1:1, if he qualifies and you beat his hand you will be paid according to a hand rank chart, often with a jackpot accumulator for a straight flush.
