Poker is a family of card games based on comparing and evaluating hands. It has become popular worldwide. Players enjoy poker at casinos, at home and in community card games.

In a typical poker game, players bet over the best hand they can make. The winner is determined by the highest combination of five cards. A poker player may choose to raise or fold when they are unsure of their hand or when they feel they have been beaten.

Most modern poker games are played with a standard deck of cards. Card values vary depending on the type of game and the rules of the dealer.

Poker has three basic structures: fixed-limit, pot-limit and no-limit. Pot-limit is the most common. Unlike fixed-limit, this version of the game allows a player to bet any amount up to a fixed pot.

Players can also voluntarily replace cards they have already discarded. They are allowed to discard up to three cards. If they do not have enough chips, they may go all-in.

Each hand is dealt clockwise around the table. Depending on the game, the cards can be dealt face up or face down.

After the cards are discarded, another round of betting occurs. The players can replace their cards or take new ones from the top of the deck.

Poker can be played on a computer. This is commonly done with one user per account. Some online sites offer multi-tabling, which requires a different browser and a separate account.
