Poker is a card game played around the world. It is one of the most popular and widely played games, with the name and jargon permeating American culture.

In poker, each player “buys in” by placing a certain number of chips (money) in the pot. This is called an ante or bet, and the amount is usually set by the rules of the particular variant being played.

Players then place their bets (or raises) in each betting interval, in turn, and must make their contributions at least equal to those of the players before them. If no other players in the betting interval raise their bets, a player may say “check”—that is, fold his hand and remain in the game without making any further bets or raising.

When a player’s hand is revealed, he has two personal cards and five community cards. The player with the best combination of those personal cards and the community cards wins the pot.

The highest possible poker hand is a royal flush, which is made up of the following cards: an ace, king, queen, and jack in the same suit. The second-highest hand is a straight flush, which contains any 5 cards in the same suit.

Other winning hands are a full house, which is made up of 3 cards in the same rank and 2 other unmatched cards; a flush, which contains any 5 cards in the suit; and three of a kind, which is made up of three cards in the same rank and two other unmatched cards. If two or more hands tie on a given rank, the cards outside the hand break the ties.
