The standard payout for any winning hand is simple - it is even money (1-to-1). All other Straight hand combinations are ranked according to their value, and the highest ranking Straight wins. An Ace, Two, Three, Four and Five is the second highest ranking Straight.

The Joker is considered equal to the value of an Ace, if used in conjunction with other Aces.The Joker can only complete certain winning combinations:the Straight, Flush, Straight Flush and Royal Flush.The game is played with a 53-card deck, with a Joker included.
