Poker is a card game of strategy, chance and psychology that involves betting between two or more players. It is played in casinos, card rooms and private homes, and is now one of the most popular card games in the world. It has been called the national card game of the United States and its play and jargon have permeated American culture.

The object of the game is to win a pot (representing a sum of bets) by holding a winning poker hand. The highest-ranking hand wins the pot, but a player can also win by raising bets on other players, known as “bluffing.”

Each round of poker consists of one or more betting intervals. Initially, the dealer shuffles and cuts the cards, then deals them one at a time to each player, starting with the player to his or her left. The cards may be dealt face up or down, depending on the variant of the game being played.

A poker hand consists of five cards. A poker hand is ranked in descending order, from the most valuable to the least valuable. The value of a card is in inverse proportion to its mathematical frequency, meaning that the more unusual the combination of cards is, the higher the hand ranks.

Before each betting interval begins, a player must place chips into the pot—representing money—that is at least equal to the amount put in by the player to his or her right. This is a forced bet, which helps keep the game competitive.
