Poker is a card game in which players wager chips (representing money) against one another. Each player is dealt two cards and five community cards, and aims to make the best 5 card hand using their own two cards and the community cards. The best hand wins the pot. The remaining players share the remainder of the pot. There are several different games of poker, and each has its own rules.

Unlike most other casino games, poker involves significant amounts of chance, but a large part of the winning depends on strategic choices made by players on the basis of probability, psychology and game theory. The game can be played by individuals, in small groups, or in tournaments with multiple participants.

Before the cards are dealt, one or more players are required to place an initial amount of money into the pot, depending on the game variant. These are called forced bets and come in the form of antes, blinds or bring-ins.

Once the cards are dealt, each player takes turns betting (raising or calling) in an attempt to win the pot. The players reveal their hands at the end of the final betting round, and the player with the best poker hand wins the pot. In some cases, a poker hand ends in a tie, and the players with tied hands split the pot.

A common strategy in poker is to use tells, which are unconscious habits of a player that reveal information about the hand. These can include body language, facial expressions or other signals. Often, poker tells are more effective if they are subtle.
