Three card poker deals three cards to the player and three to the dealer. After an ante, the player either folds or places a play bet equal to the ante. The dealer needs a queen high or better to qualify; if it does not, the ante pays even money and the play bet is returned. An optional pair plus bet pays on the player's own hand, whatever the dealer holds. Standard advice is to play any hand of queen, six, four or better.
Room games put players against each other, with the casino acting only as host. Hold'em gives each player two private cards and five shared ones, Omaha gives four private cards of which exactly two must be used, and stud deals a mix of hidden and visible cards to each player. The casino earns a rake, a small share of each pot or a fixed fee per hour or per tournament, and has no interest in who wins.
Casino hold'em and Caribbean stud follow the same ante and raise pattern against the dealer. In casino hold'em, the player sees two cards and the first three shared cards, then folds or calls with a bet of twice the ante. In Caribbean stud, five cards are dealt to each side and the raise is also twice the ante. Both games require the dealer to qualify, and both pay bonuses on the strongest hands.
