In standard poker - that is to say in the formal casino and tournament game played internationally and the home game as normally played in North America - there is no ranking between the suits for the purpose of comparing hands - so for example the king of hearts and the king of spades are equal. There are 52 cards in the pack, and the ranking of the individual cards, from high to low, is ace, king, queen, jack, 10, 9, 8, 7, 6, 5, 4, 3, 2.

The fewer hands a category contains, the higher its rank. An additional category, five of a kind, exists when using one or more wild cards. There are nine categories of hand when using a standard 52-card deck, except under ace-to-five low rules where straights, flushes and straight flushes are not recognized. Suits are not ranked, so hands that differ by suit alone are of equal rank. However, aces have the highest rank under ace-to-five high or six-to-ace low rules, or under high rules as part of a five-high straight or straight flush. Individual cards are ranked, from highest to lowest: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3 and 2. A hand is ranked within its category using the ranks of its cards. A hand in a higher-ranking category always ranks higher than a hand in a lower-ranking category.

Įach hand belongs to a category determined by the patterns formed by its cards. In high-low split games, both the highest-ranking and lowest-ranking hands win, though different rules are used to rank the high and low hands. In low games, like razz, the lowest-ranking hands win. In high games, like Texas hold 'em and seven-card stud, the highest-ranking hands win. Each hand has a rank, which is compared against the ranks of other hands participating in the showdown to decide who wins the pot. In poker, players form sets of five playing cards, called hands, according to the rules of the game. An ace-high straight flush, commonly known as a royal flush, is the best possible hand in many variants of poker.
