An ace-high straight flush, commonly known as a royal flush
, is the best possible hand in many variants of poker.
, players form sets of five playing cards
, called hands
, according to the rules of the game
. 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 high games, like Texas hold 'em
and seven-card stud
, the highest-ranking hands win. In low
games, like razz
, the lowest-ranking hands win. 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.
Each hand belongs to a category determined by the patterns formed by its cards. A hand in a higher-ranking category always ranks higher than a hand in a lower-ranking category. A hand is ranked within its category using the ranks of its cards. Individual cards are ranked, from highest to lowest: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3 and 2. However, aces have the lowest rank under ace-to-five low
or ace-to-six low
rules, or under high rules as part of a five-high straight or straight flush. Suits are not ranked, so hands that differ by suit alone are of equal rank. Read more...
