Poker is a card game in which players place bets on the outcome of a hand. While the game contains elements of chance and gambling, there is a substantial amount of skill involved in understanding probability and game theory, and higher skilled players generally win more often over the long run of rounds and games.

The game is played with a standard 52-card deck, although some variants use more cards or add wild cards. The cards are ranked (high to low) Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2; and the highest-ranking hand wins. Some games also have wild cards, which take the rank of any suit a player wants them to.

Before each hand, one or more players must make forced bets, known as an ante or blind bets. These bets are placed into a pot before the dealer shuffles and deals the cards.

When a hand is complete, the players reveal their hands and a showdown takes place. The winner of the showdown wins the entire pot. If no one has a winning hand, the players who didn’t fold continue to bet in subsequent betting rounds.

There are many different types of poker games, but the most popular form is Texas hold ’em. In most poker games, a limit is set on the number of chips a player may raise in a given betting interval. In fixed-limit games, players may not bet more than double the previous maximum bet.
