Poker is a popular card game in which players with fully or partially concealed cards make wagers into a central pot. The pot is awarded to the player or players with the best combination of cards or to the player who makes an uncalled bet. Poker can also refer to video poker, a single-player game seen in casinos much like a slot machine, or to other games that use poker hand rankings.
The right to deal each hand typically rotates among the players and is marked by a token called a ‘dealer’ button or buck. In a casino, a house dealer handles the cards for each hand, but a button (typically a white plastic disk) is rotated clockwise among the players to indicate a nominal dealer to determine the order of betting.
The most popular poker variants are as follows:
Players each receive five — as in five-card draw — or more cards, all of which are hidden. They can then replace one or more of these cards a certain number of times.
Players receive cards one at a time, some being displayed to other players at the table. The key difference between stud and ‘draw’ poker is that players are not allowed to discard or replace any cards.
Community card poker
Players combine individually dealt cards with a number of “community cards” dealt face up and shared by all players. Each player will attempt to make the best five card poker hand using the community cards and their own face down cards. Two or four individual cards may be dealt in the most popular variations, Texas hold ’em and Omaha hold ’em, respectively.
