Poker is a game which people play with a normal set (or "deck") of 52 cards. Poker is a gambling game which involves some luck, but also some skill. In poker, players make bets against each other depending on the value of their poker hand. Bets are usually made with plastic or ceramic discs called "chips". Bets may also be made with real money, but chips are more often used because they are easier to handle and count. At the end of the game, players either swap their chips for money, or the chips are counted to determine the order of winners.
