What is a Casino?


A Casino, also known as a gambling house or a gaming establishment, is a place where people can play various games of chance for money. Casinos often add extra luxuries to attract gamblers, such as restaurants, free drinks and stage shows. Some casinos specialize in certain types of games, such as blackjack or roulette. They may also offer a full range of entertainment, such as concerts and stand-up comedy.

In the United States, casinos are legal in some 40 states. The largest concentration of casinos is in Las Vegas, Nevada; the city’s economy is almost entirely dependent on casino revenue. Other popular casino destinations include Atlantic City, New Jersey; and Chicago, Illinois. Many Native American tribes have their own casinos, as well.

Something about casinos seems to encourage people to cheat and steal, either in collusion or on their own. As a result, most casinos invest a large amount of time and money in security measures. These may include hidden cameras, security guards, and electronic surveillance.

Most casinos operate on a fixed margin, meaning that they must win a certain percentage of the money bet. This is a major reason why they provide such generous inducements to big bettors. During the 1970s, for instance, Las Vegas casinos famously offered big bettors free spectacular entertainment, reduced-fare transportation and elegant living quarters.

In the 1990s, however, casinos became choosier about which gamblers they welcomed. They began to concentrate their investments on the high rollers, who are more likely to spend a lot of money and bring in friends. As part of this strategy, they began to offer such things as specialized high-roller rooms and private casino hosts. They also invested in technological advances such as “chip tracking,” which allows the casino to monitor bets minute by minute and quickly discover any statistical anomalies.
