Poker is a card game where players use their cards to build the best hand possible. The hand can be a combination of five community cards and the player’s own cards.

Poker games are played in casinos, private homes and on the Internet. Players buy a certain number of chips and contribute to a pot. They may bet, fold, check, raise, or call. If they don’t get called, they win without showing their hand.

Poker is played with a standard deck of cards, usually black or blue, though some games are also played with strips of paper. Each chip is worth a fixed amount, typically 10 or 25 whites. A chip worth two, four, or five reds is a “blue chip”.

Before playing, each player is required to place an ante into the pot. This amount is based on the stakes of the game. Once the ante is in place, the dealer deals cards to the players.

After each round of dealing, a betting interval is set. A betting interval is a period of time during which the player who is not in the lead can bet or call.

Once the betting interval ends, the dealer deals a new round of cards to the remaining players. Each of these cards is face up until a player’s jack appears.

A betting interval begins when the first player bets and ends when all players have checked. When the last player has checked, a showdown occurs.
