Poker is a card game in which players place chips (representing money) into a common pot during each betting interval. The player with the highest hand at the end of a betting round wins the pot. A hand can be made up of two cards or five cards. The game is most popular in North America, where it has been called the national card game and its play and jargon have become widely prevalent in American culture.

Before dealing the cards, each player must ante a minimum amount of money (the amount varies by game). After this, all players are dealt two cards face down. If the cards are suited, the higher-ranking suit breaks any ties.

Once all players have their cards, a round of betting begins. The players that called the biggest raise must then match it or fold their cards. If everyone folds, the cards are dealt face up on the table and a new betting round starts.

The goal is to form the best 5-card poker hand, which wins the pot – the total amount of bets placed during the hand. Generally, it is better to bet when you have a strong hand than to call weak hands. This way you force the other players to fold their weaker hands and win more money. While luck plays a major role in the outcome of a particular hand, poker strategy is largely determined by the decisions you make and your ability to read other players’ actions, particularly their tells. Many poker books have been written about various strategies, but it is important to develop your own by self-examination and analysis of your own results.
