Poker is a card game played between two or more players. It involves betting and the use of strategies based on probability, psychology and game theory.

The first player to act may either call the current bet or raise it. A player can also fold their hand, thereby removing it from play and reducing the amount of money that is at risk.

This can be a full house of 3 matching cards of one rank, a flush of 5 consecutively ranked cards, or a straight of five unmatched cards that skip around in rank but are from the same suit.
