Poker is a card game that involves two or more players. The ideal number of players is six to eight, although it can be played with fewer players. Each player makes bets that are combined into a pot. The player with the best poker hand wins the pot. Another way to win the pot is to make a bet that no other player calls.

The rules of poker vary from game to game. Some variations have different betting structures and strategies. Some players make their bets before the cards are dealt, while others call with the highest cards in the deck. In general, players wait until there are two pairs in the deck before going all-in. In addition, players are not allowed to fold their hand unless they are dealt an Ace.

The most common form of poker is Texas Hold’Em. To begin a game, players make an ante, which is usually a small bet, such as $1. If the player has a high hand, the next player to act will call. Otherwise, the player will bet a fixed amount into the pot. Usually, the highest-ranking hand wins the pot. In each betting round, players place their bets clockwise.

In some games, players must purchase chips. In general, the minimum number is 200, although a higher number is required for more players. The chip values vary between games, but the white chip is the lowest-valued. A blue chip is worth ten or twenty white chips, and a dark-colored chip is worth only two, four, or five reds. Players “buy in” to a game by buying chips.
