A casino is a place where people can gamble on games of chance. While it is true that a variety of other amenities like restaurants, lighted fountains and stage shows help attract visitors, casinos would not exist without the games of chance that make up the majority of their billions in profits each year. Slot machines, blackjack, poker, craps and other table games account for most of the income generated by casinos. The history of gambling dates back thousands of years. It was practiced in some form by almost every civilization from ancient Mesopotamia and Greece to Napoleon’s France and Elizabethan England.

Modern casinos are heavily regulated. They employ security personnel and have video cameras throughout the premises. In addition, the games themselves are closely watched for any signs of cheating or stealing, either in collusion with other players or by individual players. Roulette wheels, for example, are regularly monitored electronically to discover any statistical deviation from their expected results. The large amounts of money involved in the operations make casinos susceptible to fraud, but electronic surveillance and other preventive measures reduce the risk significantly.

In spite of these precautions, it is still possible for gambling addicts to cause significant damage. Studies indicate that compulsive gamblers shift spending from other forms of local entertainment and reduce employment opportunities, and that the cost of treating problem gamblers can often offset any economic gains a casino might bring to the community.
