Poker is a card game that includes an element of luck and requires skill in order to win. Over time the application of skill will virtually eliminate the element of chance in a given hand. There are many different types of poker, but most of them have certain essential features. The objective of the game is to win the pot, which is the sum of all bets placed during one deal.

The game is started by the players placing an initial amount into the pot, known as the ante or blinds. Depending on the rules, players may also place additional chips into the pot before dealing. This is called a bring-in, and it is intended to give players an incentive to play their best hands.

Players then receive two hole cards, and begin a betting round. During the betting round, players may choose to call (match) or raise a bet. Alternatively, players may fold.

If a player has the highest five-card hand, he wins the pot. The value of a poker hand is determined in inverse proportion to its mathematical frequency, and the more unlikely the combination, the higher the hand rank. Players may also bet that they have a high-ranking hand when they have not, a strategy known as bluffing.

Poker is usually played with a standard 53-card pack, including the joker, which counts as a wild card. The ace of spades, jack of diamonds, and jack of hearts are also considered to be one-eyes.
