Poker is a card game played by two or more players and involves betting on the outcome of a hand. The game is very popular and is played in casinos, private games, and online. In addition to its recreational value, it is also a game of skill in which the objective is to minimize losses with poor hands and maximize wins with good ones.

A number of variations of the game exist, each with a unique set of rules. Some of these rules are universal while others vary by game type and region. Traditionally, cards are dealt to each player one at a time while a token, known as the button (or buck) is rotated around the table to indicate a nominal dealer for each hand. The button is a mark that indicates the player who has the right to act first in each round of betting.

In most forms of poker, the winner is determined at the end of the last betting round when all players show their cards. The player with the best hand wins the pot. In some cases, several players may still be in the hand at this point and a showdown will take place.

Soft play is penalized in poker and can result in penalties that include the forfeiture of chips or even disqualification. This is not intended to discourage players from playing poker but rather to ensure a fair and safe game for all participants. Examples of soft play include: showing a hand to another player, discussing strategy with a non-player or spectator, and repeatedly acting out of turn. Maintaining proper card and chip visibility and countability is also important.
