Poker is a card game played between two or more players and involves betting on the outcome of the hand. The game is believed to be an ancestor of blackjack and rummy, among others. There are many different variations of the game, but they all share some basic rules. Each player places chips into the pot (representing money) to make a bet. The player who holds the best five-card hand wins the pot. Players may also bluff, betting that they have a good hand when they do not.

The highest-ranking poker hand is a royal flush, consisting of a 10, jack, queen, king, and ace of the same suit. Four of a kind is made up of 4 cards of the same rank (but different suits), and a pair contains 2 matching cards of one rank and 3 unmatched cards of another rank.
