Poker is a card game played by two or more players on a table. It involves betting between deals, and the winner of each hand is determined by the player who contributes the most chips (representing money) into the pot. Often, players will place bets that are less than the amount contributed by the player before them. This is known as bluffing, and can be an effective strategy in certain situations.

There are many different poker variants, and the rules of each differ slightly. However, most have similar features. One common feature is that there are usually several rounds of betting between each deal, with the player to the left of the dealer acting as the button. The button is a position of privilege, as it allows the player to make the first bet in each round.

Each player begins the game with two personal cards dealt to them face down and five community cards on the table. Players can form hands from these by making combinations with the cards in their own hand and those on the table. A high-card combination wins a hand. This can include a royal flush, which is an Ace, King, Queen, Jack, or ten of the same suit. Other winning combinations include a full house, which is three matching cards of a rank and two matching cards of another rank, a straight, which is 5 consecutive ranks in the same suit, and a pair.
