Draw Poker Jacks or Better is played with a standard 52-card deck and one Joker. The Joker may be used as an Ace or as any card that completes a straight, flush, or a straight flush.
Players are dealt five cards face down, one at a time, in rotation. A round of betting begins (check, bet, call, raise, or fold). A player's hand must qualify with a pair of Jacks or better (higher) to open the pot. If no player has a pair of Jacks or better, the hand ends and the ante remains in the pot. A player who opens the pot must show openers, whether the hand is called or not, in order to win the pot. The remaining players may discard any number of their original cards and have the same number of cards replaced by the dealer. Another round of betting occurs. The player with the highest ranking five-card poker hand wins. Five Aces is the best possible hand (four Aces and the Joker). In the event of a tie, the pot is split equally.
