What Is a Casino?


A casino is a place where people can gamble and play games of chance. While casinos offer a variety of other attractions and amenities, they mainly draw people to gamble. They often feature restaurants, free drinks, stage shows, and dramatic scenery. Casinos are also found in hotels, resorts and on cruise ships. In the United States, there are more than 3,000 casinos.

In addition to offering slot machines and other gambling equipment, many casinos feature table games such as blackjack, craps, baccarat and roulette. Some even have poker rooms. In the modern world, casino gambling has become more and more popular, and it is estimated that over 51 million people — about a quarter of all Americans — visited a casino in 2002.

Casinos make their money by charging a rake to players for the use of their facilities. This rake is usually set at a percentage of each game’s total bets. The amount of rake a player pays is dependent upon the rules and strategy used for each game. In games where skill is involved, such as blackjack and Spanish 21, the house edge is much lower than in pure luck games such as roulette.

Most casinos are based in large cities and are designed to appeal to tourists, with luxurious accommodations and high-end shops. The Bellagio in Las Vegas, for instance, is renowned for its fountain show and lavish rooms. Some casinos are even located on American Indian reservations, which are exempt from state antigambling laws.

Although the glamour and glitz of casinos attract many visitors, they would not exist without the games of chance that provide the billions of dollars in profits that casinos earn each year. While musical shows, lighted fountains and shopping centers help attract customers, the real money is made by games such as slot machines, roulette, baccarat, craps, blackjack, and poker.

While the games may be random, casinos are increasingly using technology to help control the house edge. For example, some casino chips now have built-in microcircuitry that enables the casinos to monitor exactly how much is being wagered minute by minute; electronic systems on roulette wheels enable them to discover any statistical deviations quickly. Casinos are also expanding their use of video cameras to increase surveillance coverage and improve security.

Casinos also reward their best players with comps, or free goods and services. These can include hotel rooms, meals, show tickets and even limo service. This type of customer loyalty is an important part of the casino business model, as it helps to offset the high cost of running a casino. In 2005, the average casino patron was a forty-six-year-old woman from a household with above-average income. This age group was more likely to visit a casino than older or younger adults.
