Poker is a widely popular card game with a variety of different regional and contemporary variations. Players typically attempt to accumulate a hand of cards that will beat the hands of their opponents, though the particular details of the rules are determined by the game and room type in which it is being played. While some forms of poker are based more on luck, other forms of the game involve more skill and strategy. In the game of poker, the goal is to win money by collecting the best combination of five cards available, either by bluffing opponents or predicting how they will play.
