Poker is a family of comparing card games, which are widely played all over the world. It is often believed to have ancestry with the Persian game as nas, the French game primero, and the English game brag. There are a few different poker variants, but all are based on the same basic mechanic of betting in rounds.

The game is usually played with a standard 52-card deck, though the number of cards may vary depending on the type of poker. Players are required to make forced bets, but their hands develop between rounds.

When a player makes a bet, it is called a raise. If a player thinks they are bluffing, they can call. This type of betting is a feature of most modern poker games.

During a round of betting, all but one player folds. After a player has folded, the rest of the players in the hand must show their hand. Once the hands are revealed, the player with the highest hand wins. In other variations, the pot is split between the highest and lowest hands.

A player can make bets with plastic chips or ceramic chips. Chips come in different colors, but most are black or green.

Several poker variants use a wild card. A wild card is a card that is not part of the deck. For example, a stud poker hand may require the player to have five cards.

Players can also choose to discard their cards. These actions are determined by the rules of the game and the psychology of the players.
