Poker is a card game played between two or more players and with money (called chips). The objective of the game is to have the best five-card hand at the end of the round. The player with the best hand wins all the money in the pot. The game has many variations. Some games award the pot to the highest hand according to the standard ranking of poker hands; other games split the pot between the highest and lowest hands.

The game is typically played with a dealer who is responsible for shuffling and dealing the cards. The dealer may be a player or a non-player. Some games use a special chip to designate the dealer for each round of play. In some games, the player to the left of the dealer is given a turn to cut and deal the cards. Depending on the rules of the game, the cards may be dealt face-up or face-down.

In most poker games, the best hand is a pair of matching cards, three of a kind, straight, or flush. Some games have a lower ranking, such as seven-five-four-three in two or more suits, and treat the ace as the lowest card, making a full house the best possible hand.

During a betting round, each player can raise or call the bets of the other players. A player can also check, meaning that they will not place any more chips into the pot.
