A casino is a place where people can play games of chance for money. Although casinos offer many luxuries to attract visitors, such as restaurants, shopping centers and stage shows, they would not exist without the billions of dollars in profits that people make by gambling on games of chance like blackjack, roulette, baccarat and craps. Casinos often include a large number of slot machines.
In general, security is a big issue for casinos. With so much money flowing through them, both patrons and staff may be tempted to cheat or steal, either in collusion with each other or independently. To discourage this, casinos invest a lot of time and money in security measures. These range from simple to elaborate. Some of the more sophisticated systems feature high-tech “eyes-in-the-sky” cameras that monitor every table, change window and doorway, and can be adjusted to zero in on suspicious patrons. Table game croupiers and dealers are also heavily monitored, with the croupier’s and dealer’s attention frequently diverted by higher-ups to check for suspicious betting patterns.
Gambling almost certainly predates written history, with primitive protodice (cut knuckle bones) and carved six-sided dice found in ancient archaeological sites. But the modern casino as a central place for people to find a variety of ways to gamble under one roof did not develop until the 16th century, when a gambling craze swept Europe. Italian aristocrats began to hold private parties at small clubhouses called ridotti, where they could socialize and play their favorite games.
