A casino is a place where people gamble on games of chance. Casinos often add a variety of luxuries to their facilities to attract customers, such as restaurants, free drinks and stage shows. There have been less lavish places that house gambling activities, however.
A modern casino usually employs a large physical security force and a specialized surveillance department that operates its closed circuit television system, known in the industry as “eye in the sky.” Detailed knowledge of how casinos operate and what games are played there is also helpful for detecting anomalies in game play. For example, the routines of card dealing, the expected reactions of players and the locations of the betting spots on a table all follow certain patterns. By learning those patterns, a person can spot unusual behavior and make informed decisions about whether to continue playing.
The majority of casino games are pure luck, although some do have an element of skill (such as poker). Casinos profit from these games by taking a commission on bets placed by patrons or by charging an hourly fee for use of the tables. In addition, the casino makes money by offering complimentary items to big bettors, known as comps, in the form of food, free hotel rooms and tickets to shows.
Most casinos offer a wide range of games, including baccarat (in its popular variation known as chemin de fer), roulette and blackjack. Some casinos specialize in particular games, such as sic bo (which spread to European and American casinos in the 1990s) or fan-tan.
