The modern casino is like an indoor amusement park for adults. It has elaborate themes, hotels, restaurants and nongambling activities, but it would not exist without the billions of dollars in profits generated by games of chance. Slot machines, blackjack, roulette, craps, baccarat and more provide the thrills that attract the crowds.
The precise origin of gambling is unknown, but it seems to have been part of every society from ancient Mesopotamia and Greece to Elizabethan England and Napoleon’s France. Today, casinos are located all over the world. Most are owned and operated by commercial corporations, but some are nonprofit organizations. Some are built on reservations controlled by Native American tribes, which are exempt from state antigambling laws. Others are built in tourist destinations, such as Las Vegas, Macau and Reno. Many European countries amended their laws in the 1980s to permit casinos.
Casinos are designed to give patrons the impression that they are not only winning, but getting more and more money as they play. This is achieved by giving the house a mathematical edge in all games, and by offering extravagant inducements to big bettors. These include free spectacular entertainment, limousines, reduced-fare transportation and luxurious living quarters. Security is another area of high emphasis, as it is believed that something in the nature of casino gambling encourages cheating and stealing. Statistical deviations from the expected values of various games are easily spotted by security personnel who are familiar with the idiosyncrasies of individual games.
