What Is a Casino?


A casino is a gambling establishment that accepts wagers on games of chance. These establishments may also offer a variety of other services, such as restaurants, hotels, retail shopping and entertainment events.

Casinos make money by offering their patrons a statistical advantage over the house. This edge is called the “vig” or the rake, and can be as high as two percent on some games.

The casinos’ advantage makes them attractive to wealthy gamblers, who can afford to play for a higher percentage of their income than other players. In return, these high rollers receive special treatment at the casinos. They are often treated as VIPs, receiving free entertainment and luxury suites as well as free transportation to and from the casino.

Security is a big part of casino operations, with surveillance personnel on every table and floor in the casino. They watch the game for cheating, palming, switching cards or dice and other suspicious activities. They are trained to spot routine patterns in a player’s movements and reaction, as well as the way a player looks.

They use elaborate surveillance systems that allow cameras in the ceiling to watch every table, change windows and doorways and view a player’s movements as they move between tables or machines. These video feeds are recorded, and security workers can review the tapes if a cheat is detected.

In addition, casinos provide incentives to attract gamblers, such as free food and drink. These inducements keep patrons on the casino floor longer and increase the amount of money they spend there. They also make them feel more comfortable, since they do not have to worry about losing their money.
