What Is a Casino?


A casino is a place where people can gamble on games of chance. Modern casinos often look like an indoor amusement park for adults, with the bulk of the entertainment coming from gambling on games of chance such as slot machines, black jack, roulette, baccarat, craps and keno that provide billions in profits each year. While lighted fountains, stage shows and elaborate theme parks help draw in visitors, casinos would not exist without the underlying games of chance.

A modern casino combines a wide variety of gambling activities with luxury amenities to appeal to all types of patrons. These include restaurants, free drinks and dramatic scenery. Casinos can be found in cities, towns and even in the countryside, although most are located in states that allow gambling. In addition to attracting visitors from nearby areas, casinos also attract tourists who travel long distances. Many of these visitors are repeat customers.

Despite their high-tech appearance, casino operations are fundamentally business enterprises that must make a profit. As a result, they are structured to ensure that the house always wins. Every game offered by a casino has a mathematical advantage for the house, which can be expressed in terms of expected value (which is uniformly negative from the player’s perspective). This mathematical expectation is called the house edge.

Gambling is an inherently risky activity, and casinos spend a large sum of money on security. Casino employees watch over games from all angles, and each table has a manager or pit boss that watches for signs of cheating. Chip tracking technology allows managers to know exactly how much is being wagered in a minute, and electronic systems monitor the outcome of table games to quickly detect any statistical deviation from expectations.

While the vast majority of a casino’s income comes from games of chance, there are still other sources of revenue. For example, casino owners often give complimentary items to players who place large wagers, or comp them. These perks are intended to encourage players to play more and to reward those who do. Casinos also collect a commission on rake bets, which are bets made by the house against other players.
