You and fellow players are dealt two cards each whilst the dealer is dealt one face up. If your first 2 cards add up to 21 (an Ace and a card valued 10), that's Blackjack! If they have any other total, decide whether you wish to 'draw' or 'stay'. You can continue to draw cards until you are happy with your hand.
In blackjack, players attempt to reach a score of 21 without exceeding it before the dealer hits 17. You can win if you don't bust and your total is higher than the dealer cards. Hitting exactly 21 can mean even bigger winnings.
In poker, players form sets of five playing cards, called hands, according to the rules of the game.[1] Each hand 2️⃣ has a rank, which is compared against the ranks of other hands participating in the showdown to decide who wins 2️⃣ the pot.[2] In high games, like Texas hold 'em and seven-card stud, the highest-ranking hands win. In low games, like 2️⃣ razz, the lowest-ranking hands win. In high-low split games, both the highest-ranking and lowest-ranking hands win, though different rules are 2️⃣ used to rank the high and low hands.[3][4]
Each hand belongs to a category determined by the patterns formed by its 2️⃣ cards. A hand in a higher-ranking category always ranks higher than a hand in a lower-ranking category. A hand is 2️⃣ ranked within its category using the ranks of its cards. Individual cards are ranked, from highest to lowest: A, K, 2️⃣ Q, J, 10, 9, 8, 7, 6, 5, 4, 3 and 2.[5] However, aces have the highest rank under ace-to-five 2️⃣ high or six-to-ace low rules, or under high rules as part of a five-high straight or straight flush.[6][7] Suits are 2️⃣ not ranked, so hands that differ by suit alone are of equal rank.[8]
There are nine categories of hand when using 2️⃣ a standard 52-card deck, except under ace-to-five low rules where straights, flushes and straight flushes are not recognized. An additional 2️⃣ category, five of a kind, exists when using one or more wild cards. The fewer hands a category contains, the 2️⃣ higher its rank.[9] There are 52 ! ( 52 − 5 ) ! = 311,875,200 {\displaystyle {\begin{matrix}{\frac {52!}{(52-5)!}}=311{,}875{,}200\end{matrix}}} ways to 2️⃣ deal five cards from the deck but only 52 ! ( 52 − 5 ) ! 5 ! = 2,598,960 2️⃣ {\displaystyle {\begin{matrix}{\frac {52!}{(52-5)!5!}}=2{,}598{,}960\end{matrix}}} distinct hands, because the order in which cards are dealt or arranged in a hand does not 2️⃣ matter.[10] Moreover, since hands differing only by suit are of equal rank, there are only 7,462 distinct hand ranks.[11]
