Poker is a card game in which players compete to place bets into a central pot. The player with the highest hand wins the pot. Players may bluff to increase their chances of winning.

There are many variants of the game, but the most popular form is played with six to eight players. Each player places a bet (representing money) in front of them before they receive their cards, which are dealt in turn from the dealer. Some games require forced bets, usually an ante and a blind bet. The ante and blind bets are collected in a pot, which is the total of all bets placed in one deal.

After the first betting round, a fourth community card is revealed, called the Turn. A second betting round ensues and then the fifth and final community card, known as the River, is revealed. A third betting round then occurs.

After a player has received their cards, they can either call the previous bet or raise it. When a player raises the bet, all other players must either call it or fold. In the case of a tied hand, the winner is determined by the higher ranking hand. High hands include a flush, which contains five consecutive cards of the same suit; a straight, which skips around in rank but not in suits; and three of a kind, which is made up of three matching cards of one rank. Ties are broken by secondary pairs, which consist of two cards of one rank and another unmatched card; and full house, which is a combination of three of a kind and a pair.
