Casino can mean:
a gambling establishment or room where games of chance are played, and the primary activity is gambling. A casino may also refer to a group of such establishments, or to the business of providing such establishments. A casino may also include restaurants, hotels, entertainment venues and other facilities for recreational activities.
Gambling is a popular pastime and has been enjoyed by many throughout history. Casinos are places where people can try their hand at a variety of gambling activities, including table games like blackjack and roulette, and slots. Some casinos offer more luxurious experiences, with stage shows and free drinks. But even less lavish places that house gambling activities can be called casinos.
Casinos make their money by accepting bets from patrons and paying out winning bets. Every game has a built in mathematical advantage for the casino, which can be lower than two percent, but it adds up over the millions of bets placed each day. To offset this, casinos typically charge higher bet minimums and maximums and take a percentage of the total amount of bets made by patrons.
Casinos also employ a large number of security personnel. The personnel typically divides into a physical security force and a specialized surveillance department. The latter is often equipped with a high-tech “eye in the sky” system that allows surveillance workers to view all casino tables, changing windows and doorways through one way glass from a control room.
