Poker is a card game played between two or more players and involves betting. It is a fast-paced game with many rounds (hands). The goal of the game is to have the highest ranking hand when all cards are shown. This is accomplished by either having a good hand or bluffing. The player with the highest hand wins the pot or all bets placed during that round.

A hand in poker consists of five cards. The value of the hand is in inverse proportion to its mathematical frequency, meaning that a very rare hand has a much higher value than a common one. In addition to the five cards, the values of a poker hand are determined by the number and strength of each card.

Before a hand is dealt, the players must place bets, which are called blinds. Each player has the option of raising the bet by a certain amount, up to four times per betting round. A player may also check, which means that he or she passes on the opportunity to bet.

The dealer then reveals three community cards on the flop. Then the remaining players must act on their hands. A full house is made up of three matching cards of one rank and two cards of another rank. A flush consists of any five consecutive cards of the same suit (skipping ranks is okay). Two pair consists of two matching cards of the same rank plus two unmatched cards.
