What Is a Casino?


A Casino, also known as a gambling house or gaming establishment, is a place where people can gamble. Most casinos feature a variety of games, including roulette, blackjack, and poker. Some even have shows and other entertainment.

Casinos are often built near or combined with hotels, resorts, restaurants, retail shops, and cruise ships. They may also offer live entertainment, such as concerts and stand-up comedy. Casinos are sometimes referred to as gaming houses or officers’ mess (in military and non-military usage).

Gambling predates recorded history, with primitive protodice and carved six-sided dice found in archaeological sites. However, the modern casino as an institution did not appear until the 16th century during a gambling craze in Europe. Italian aristocrats would meet in small private gambling clubs called ridotti, where they could enjoy their favorite activities without interference from the authorities.

Because of the large amounts of money handled within a casino, there are security concerns. Staff members are trained to spot blatant cheating, and patrons are often monitored by surveillance cameras. Security personnel also use the routines and patterns of the casino’s games to identify anomalies.

A casino’s revenue comes from a combination of game-specific house edge, or expected value, and the vig, or rake. The latter is a commission taken by the casino from players at table games such as baccarat, chemin de fer, and trente et quarante. Some casinos also take a percentage of the winnings at slot machines. In addition, a casino’s gross profit can be eroded by the cost of treating problem gambling and the loss of productivity caused by people who cannot control their gambling habits.
