Originally a game of gambling, poker is now an international sport. It can be played at casinos, private homes, and online. Poker is the national card game of the United States, and has spread around the world.

The earliest forms of poker were likely a variation of the French game poque. Poker can be played with anywhere from five to seven players. The ideal number of players is about six to eight.

The game is played with a 52-card deck. Players are dealt cards one at a time. They may choose to discard two or three cards, thereby adding to the deck.

There are hundreds of variations of poker. Each variant has a different method of card dealing. A poker table typically features chips made of ceramic or plastic. These are usually red or blue in color. Poker chips are used to place bets, but they may also be used for cash wagers.

A pot is a collection of all bets made by all players during one deal. This pot may be won by the highest-ranking poker hand. It can also be won by making a bet that no one else calls.

The showdown is a climax to the game. After all the betting has stopped, the player with the best hand is declared the winner. A “backdoor flush” is achieved by hitting a needed card on the turn and river.

The name poker is derived from the French poque, and may have been derived from the German pochen or the Persian as nas. The earliest forms of the game may have been played by French settlers in New Orleans, and by Persian sailors on the high seas.
