Poker is a card game played by two or more players. Each player puts in a wager, called the pot, that he or she believes will win the hand. There are a number of ways to bet in poker, depending on the variant being played. Players can call, raise, and fold. The best hand wins the pot. There are also rules for how the money at the table is shared if more than one player has a winning hand.

The history of poker is full of rumours and apocrypha, but it is generally agreed that the game developed from a variant of the 17th century French game poque, which itself was derived from the Spanish game primero. The name of the game comes from the verb to “play” or “to bluff.” Poker was first popular in the United States as part of the Wild West, where it became a fixture at saloons and gambling houses.

There are many different poker variants, each of which has its own rules and strategy. Some are played in tournaments, while others have a more casual atmosphere.
