Poker is a card game in which players make bets on the strength of their hands. It involves a high degree of bluffing and deception. It has become a popular global card game, with many variants.

Traditionally, poker is played with a standard 52-card deck. The cards are dealt to each player individually, face down. Then the players bet on their hands in turn, putting chips into the pot if they call the bet; raising it if they want to increase the amount that they put into the pot; or folding (and thus conceding their hand) if they do not have a strong enough one. A winning hand takes the pot.

The best way to learn poker is by watching experienced players and observing how they react in certain situations. This helps players develop quick instincts. It also teaches them to observe subtle physical tells, which are often more important than the actual cards.

Some poker games require players to place a small bet before they receive their cards, called a blind bet. This is in addition to, or instead of, the ante.

Some poker variants have a dealer, who is responsible for shuffling and dealing the cards to each player. This role is typically passed clockwise around the table after each betting round. Occasionally, the deck is cut by a player who is not a dealer, but this is done only if that player has the right to do so.
