Poker is a card game where players bet that they have a better hand than the other players. Players can also bluff, hoping that other players will call their bets, so they can win the pot. A hand contains five cards. The value of a hand is in inverse proportion to its mathematical frequency, meaning that the more unusual a combination is, the higher the hand rank.
Before the deal begins, all players put in an amount of chips (representing money) into a common pot. Depending on the specific poker variant, this player may have the privilege or obligation to bet first in each betting interval.
The dealer shuffles the pack and deals five cards to each player one at a time face up, beginning with the player to his or her left. The player to the right of the dealer has the option to cut the cards. This gives the player who cuts the cards the position of button for the next deal.
The first player to act can raise, call or fold his or her cards. After the initial deal, each player can discard cards to improve their hands. In the end, the highest hand wins. A high hand has two distinct pairs of cards, a straight, or three of a kind. If there is a tie, the highest unmatched card breaks it.
