Poker is a card game that involves betting between players and requires skill to win. Although some forms of the game may have different rules, all involve a pot, which is the total amount of bets made at each street (betting rounds). The winner of a hand earns this pot.

The first round of betting begins when each player receives two hole cards. This is called the flop. Players then have the option to call a bet, raise it or fold.

After the flop, the dealer deals one more card face up. This is the turn. After the turn, there is a final round of betting before all cards are revealed at showdown. The player with the best five-card poker hand wins the pot.

Poker can be played with a number of players from 2 to 14, although the ideal number is 6, 7, or 8. The objective is to win the pot, which is the sum total of all bets placed during the course of a deal. The winning hand is a poker hand that contains five cards of the same rank. Its value is in inverse proportion to its mathematical frequency, which means that more unusual poker hands have higher values than common ones.

A player may also bluff, which is when they bet that they have a superior poker hand but are actually bluffing to get other players to call their bets. Bluffing can be done by changing body language, eye contact, and other gestures.
