Official poker is a game in which players compete for an amount of money or chips contributed by all members of the game (the pot). The game is played by individuals and involves both luck and skill. While luck plays a significant part in the game, skilled players tend to win more often than those who play purely on chance.

The game is normally played with a standard 52-card pack. The cards are shuffled and dealt in one round. Typically, each player places a bet before the cards are reshuffled. If a player wishes to remain in the game without betting, they may “check.” A player who checks must call any bet raised during that interval and cannot raise the bet again.

Each player purchases a certain number of chips at the beginning of the game. A white chip is generally worth a minimum ante or bet of 10 or 20 or 25 whites; a red chip is usually worth five whites. If a player wishes to receive an odd chip, they must ask the dealer for this privilege. The dealer will then award this chip to the player whose hand wins the pot (or, in the case of a high/low split, to the player with the highest-ranking hand).

A player may request to see a winning hand at showdown, provided that it has not yet been mucked. However, this is a privilege that can be revoked for abuse. Players must be careful not to reveal information about their holdings, such as how much of a raise they made on the flop. This can unintentionally give their opponents a clue as to the strength of their own hands.
