Poker is a gambling game in which players make bets using their cards. Each player antes an amount based on the game being played and then places their bets into the middle of the pot. The player with the best hand wins the pot. The betting is done clockwise and a player can fold or raise his initial bet.

Poker is played with a standard deck of 52 cards. Some variations use more cards and sometimes add jokers. The cards are ranked from Ace to King. They are also rated from ten to eight, seven, six, and five. The Ace may be high or low, but the rest of the cards have a suit. All hands in poker contain at least five cards, although in some variants the hand can have up to eight cards.

The game is played with any number of players. However, the number of players is ideally between six and eight. The pot is the total of all bets placed by all players in a single deal. The player with the highest hand wins the pot. Otherwise, the winner of the hand is the person who made the last bet and no one else has called.

In a hand of four cards, the winner is the one with the highest pair of cards. The second highest pair wins in a tie. If two players have the same high and low, the high card in the other hand will break the tie.
