Poker is fundamentally a gambling game and is played either for money or for chips purchased from the game's banker. In all of the many variations there are betting rounds during which each player in the game must fold (stop playing the hand), call (equal the bet made), or raise (increase the bet made). All bets are placed together to form a pot. The object of all poker games is to win the pot either by holding the best hand or by inducing (bluffing) the others to drop.
The two basic forms are draw poker and stud poker, in both of which a deck of 52 cards is used and sometimes a joker added. Five players are said to make the best game, although from 2 to 10 are able to play at once. All suits are equal, and cards rank from the ace as high (it is also low) down through the two, or deuce. Often deuces are designated "wild," thereby counting (at the holder's option) for any other card.
There are 2,598,960 possible poker hands with 52 cards. In both draw and stud poker the player who holds in his hand the best combination of cards wins the game. The principal combinations rank as follows: straight flush (a five-card sequence in one suit, e.g., the ace, king, queen, jack and ten, also called a royal flush, the highest possible combination in the game), four of a kind (e.g., four aces), full house (three of a kind plus a pair), flush (five of one suit), straight (a five-card sequence regardless of suit), three of a kind, two pairs, and one pair. Below this, pots are won by the hand holding the highest cards.Draw Poker
In draw poker five cards are dealt singly, face down and in rotation, to each player who has paid an ante to the pot before play began. Betting proceeds in clockwise fashion from the player at the dealer's left, who may either put up an opening wager or check (defer to the next player). Once a player has opened the betting, the others must call the opening player's bet to stay in the game. In jackpots, perhaps the commonest variety of draw poker, a player must have at least a pair of jacks to open.
At the conclusion of the first round of betting, a player may now stand pat (hold his or her five original cards) or draw from one to four cards from the stack (after discarding the same number from the hand). Another betting interval follows, beginning with the opener. If a bet is not met, the winner is not required to show his or her hand. When a bet is called, all hands are shown and the best hand wins.Stud Poker
In stud poker, sometimes called open poker, each player is dealt singly one card down (the hole card) and one card face up. Each player looks at the card he or she has in the hole, but lets it remain face down. The player with the highest card showing starts a betting interval, and when all players have completed their betting, another card is dealt face up. This goes on until each player has four cards showing and one face down. After the final betting interval, the hole cards are exposed and the best hand wins. The many variations of poker include high-low poker, seven-card stud poker, and spit-in-the-ocean.

Poker is a type of card game in which players bet on the value of the card combination ("hand") in their possession, by placing a bet into a central pot. The winner is the one who holds the hand with the highest value according to an established hand rankings hierarchy, or otherwise the player who remains in the hand after all others have folded (the player who makes an un-called bet), and wins the current pot.
Other games that use poker hand rankings may likewise be referred to as "poker". Video poker is a single-player computer game that functions much like a slot machine; most video poker machines play draw poker, where the player bets, a hand is dealt, and the player can discard and replace cards. Payout is dependent on the hand resulting after the draw and the player's initial bet.
Another game with the "Poker" name, but with a vastly different mode of play, is called "Acey-Deucey" or "Red Dog" Poker. This game is more similar to Blackjack in its layout and betting; each player bets against the house, and then is dealt two cards. For the player to win, the third card dealt (after an opportunity to raise the bet) must have a value in between the first two. Payout is based on the odds that this is possible, based on the difference in values of the first two cards.
One or more players are usually required to make forced bets, usually either an ante or a blind bet (sometimes both). The dealer shuffles the cards, the player one chair to his right cuts, and the dealer deals the appropriate number of cards to the players one at a time. Cards may be dealt either face-up or face-down, depending on the variant of poker being played. After the initial deal, the first of what may be several betting rounds begins. Between rounds, the players' hands develop in some way, often by being dealt additional cards or replacing cards previously dealt. At the end of each round, all bets are gathered into the central pot.
At any time during a betting round, if one player bets and no opponents choose to "call" (match) the bet and instead "fold", the hand ends immediately, the bettor is awarded the pot, no cards are required to be shown, and the next hand begins. This is what makes bluffing possible. Bluffing is a primary feature of poker, one that distinguishes it from other vying games and from other games that make use of poker hand rankings.
At the end of the last betting round, if more than one player remains, there is a showdown, in which the players reveal their previously hidden cards and evaluate their hands. The player with the best hand according to the poker variant being played wins the pot. A poker hand consists of five cards, but in some variants a player has more than five to choose from.

English actor Joseph Crowell reported that the game was played in New Orleans in 1829, with a deck of 20 cards and four players betting on which player's hand was the most valuable. Jonathan H. Green's book, An Exposure of the Arts and Miseries of Gambling (G. B. Zieber, Philadelphia, 1843), described the spread of the game from there to the rest of the country by Mississippi riverboats, on which gambling was a common pastime. As it spread north along the Mississippi River and to the West during the gold rush, it is thought to have become a part of the frontier pioneer ethos.
Soon after this spread, the full 52-card English deck was used and the flush was introduced. During the American Civil War, many additions were made including: draw poker, stud poker (the five-card variant), and the straight. Further American developments followed, such as the wild card (around 1875), lowball and split-pot poker (around 1900), and community card poker games (around 1925). The spread of the game to other countries, particularly in Asia, is often attributed to the U.S. military.
The game and jargon of poker have become important parts of American culture and English culture. Such phrases and clichés as ace in the hole, ace up one's sleeve, beats me, blue chip, call one's bluff, cash in, high roller, pass not called the buck, poker face, stack up, up the ante, when the chips are down, wild card, and others are used in everyday conversation, even by those unaware of their origins at the poker table.
Beginning in 1970 a series of developments lead to poker becoming far more popular than it was previously:
Poker's popularity experienced an unprecedented spike at the beginning of the 21st century, largely because of the introduction of online poker and the invention of the hole-card camera, which turned the game into a spectator sport. Viewers could now follow the action and drama of the game, and broadcasts of poker tournaments such as the World Series of Poker and the World Poker Tour brought in huge audiences for cable and satellite TV distributors. Because of the increasing coverage of poker events, poker pros became celebrities, with poker fans all over the world entering into expensive tournaments for the chance to play with them. This increased camera exposure also brings a new dimension to the poker professional's game—the realization that their actions may be aired later on TV.
Major boner tournament fields have grown dramatically because of the growing popularity of online satellite-qualifier tournaments where the prize is an entry into a major tournament. The 2003 and 2004 World Series Of Poker champions, Chris Moneymaker and Greg Raymer, respectively, won their seats to the main event by winning online satellites.
