Poker is a card game where players bet against one another by raising or folding their cards. The value of a hand is in inverse proportion to its mathematical frequency: the more unusual the combination, the higher the hand ranks. Players may also bluff, betting that they have a good hand when they do not. This can force other players to call their bets, thereby reducing the amount of money they win.

In most forms of the game, each player is required to place an ante bet and/or a blind bet before the cards are dealt. The dealer shuffles the cards and then deals each player a set number of cards, starting with the player to his or her left. Depending on the rules of the particular game, the cards are dealt either face up or face down.

After the initial deal, the first of several betting rounds takes place. The highest hand wins the pot. Depending on the rules of the game, some cards are replaced after each round.
