A casino is an establishment that houses gambling activities. It is also a place where a variety of entertainment, such as stage shows, restaurants and free drinks, is offered. Although some of these luxuries help draw in customers, casinos would not exist without the billions of dollars in profits raked in by the games of chance that they offer. Slot machines, blackjack, roulette and craps are the games that generate most of this income.

The etymology of the word casino can be traced back to Italy. The original meaning was villa or summerhouse, later becoming connected with various pleasurable activities and games of chance. The modern casino is a complex facility with many different games and entertainment options. It is often a tourist destination and an economic generator for the surrounding area.

Casinos have a variety of security measures in place to prevent cheating and theft by both patrons and employees. These include a high-tech eye-in-the-sky system that watches every table, window and doorway from a room filled with banks of security monitors. Each casino employee is also assigned a higher-up supervisor who keeps tabs on them and can spot any suspicious betting patterns.

Because casinos deal in large amounts of money, both patrons and staff may be tempted to cheat or steal. While most casino workers are honest, some are not. This is particularly true for crooked dealers and pit bosses, who may try to manipulate the rules of a game in order to increase their own winnings.
