Developed in the late 19th century, poker is a card game played with a standard 52-card deck. Poker may be played with one or more players, with each player placing a bet on their hand and drawing new cards to replace those that have been discarded. Several variants of the game exist, including draw poker, Texas HoldEm, Omaha, and others.
Poker is often credited with ancestry to the French game poque and to the Persian game as nas, though it is unclear whether these games originated with poker. The game can be played in a variety of settings, including community card rooms, casinos, and online. Some players may bluff by claiming to have the best hand and betting to win, while others may make a bet to win a pot.
The game of poker is played with a standard 52-card deck, though the number of cards in the deck can vary depending on the type of game being played. Wild cards are a feature of some poker games, such as the joker, which counts as the fifth card in certain special hands. The standard poker hand is ranked by odds, and the value of the hand is inversely related to mathematical frequency.
A poker game may have several rounds of betting, with players making a bet on their hand and drawing a new card until the betting interval is over. After the last betting interval, dealing resumes, and players are said to have a “showdown”. The winner is the player with the highest-ranking hand. If there are multiple identical hands, the pot is divided among the players according to the rules of the game. A “backdoor flush” is achieved by hitting a needed card on the turn or river.
Poker may be played with as few as two players or as many as eight. The number of players may be dictated by the number of chips in the pot. In some poker games, each player may be required to contribute a certain amount to the pot before the cards are dealt. Players may also be required to shuffle their own deck before they begin to play. The game is also played with professional dealers, who charge a small fee for each hour that they are employed. Professional dealers are usually used in casinos and in poker clubs.
The name poker may have originated from a German word pochen, which is believed to have derived from the French word poque. The game is also thought to have a close kinship to the French game brelan, which is derived from a Spanish game called primero. A variation of the game, called stud poker, was introduced during the American Civil War. A variation of the game called lowball, a “split-pot” version of poker, was introduced around 1900. The game has spread to other countries, including England, France, and the U.S., as a result of broadcasts of poker tournaments on cable and satellite TV.
