Official poker is a card game where players compete for an amount of money contributed by each player (called the pot). Players use their cards to form a hand, which is ranked according to the rules of the game. The highest ranked hand wins the pot. The game is played with a standard pack of 52 cards, sometimes with one or two jokers added.

The game of poker has a long and varied history, both online and offline. Its popularity has grown in recent years, and it is now one of the most popular ways to spend time at land-based casinos and online. It is a game that involves both luck and skill, and players who understand how to play the game effectively will be more likely to win.

Players bet into a common pool of chips called the pot, which is shared among all players at a table. Each player has the opportunity to bet, call, raise or fold, depending on their position and the strength of their hand. After the betting round has completed, the remaining players with hole cards expose their hands and, with the assistance of the dealer, a winner is determined.

Players may only act within their allowed turn, meaning that they cannot raise before the other players have acted or after all players have raised in the same manner. When a player verbally states that they are going to take a particular action, such as checking, they are held to this action.
