The rules of poker vary between different games, but the basic principles are the same. Each player places a number of chips into the pot to make a bet. The player to the right of the dealer puts in a bet, and then the players to his left raise or fold. If everyone else calls the bet, the players reveal their hands. The player with the best hand takes the pot.

In poker, a hand is made up of matching cards, or two pairs, or three of a kind. A flush is five consecutive cards of the same suit. A straight is five cards of the same rank, but from different suits. A pair is two cards of the same rank, and a three-of-a-kind is three cards of the same rank. These combinations can be ranked either in order of strength or in order of their likelihood of winning the pot. In some cases, a player may win both the main pot and various side pots. The side pots are created when a player raises in an attempt to improve his or her hand. This can cause other players to fold, and the original bet amount will remain in the pot.
