Poker is a family of card games in which players compete by determining who has the best hand. The earliest known form was played with 20 cards, but in most countries, players use a standard deck of 52 cards. In some countries, the decks are shorter and play is done with 32 or 40 cards. The number of available cards, the number of players, and the number of shared cards vary between poker games. However, all poker games involve one or more rounds of betting.
Most poker games are played with poker chips. If there are seven or more players, the game is played with a standard 52-card deck. Each player purchases chips to participate in the game, with white chips being worth the least. Red chips are worth five or more whites, and blue chips are worth ten or twenty or more. The player then buys in by buying chips. Each player generally purchases one of each color, and each player plays for the same amount.
The game of poker involves a number of different betting strategies. The goal is to accumulate as many chips as possible in each round. As the game progresses, players may fold their cards, but they can still call a bet if they aren’t winning. This is called a flop. If a player wins a flop, they will win the hand. The winner of a flopped hand wins the pot.
