A casino is a place where people can gamble on games of chance. Though some casinos have musical shows, lighted fountains, shopping centers and lavish hotels, the vast majority of their entertainment (and profits for their owners) come from gambling on games such as blackjack, poker, roulette, craps, baccarat and slot machines. Casinos are found all over the world, with most in America located either in Las Vegas or Atlantic City. In addition to games of chance, most casinos offer other forms of gaming such as bingo and racetracks.
Gambling in some form is part of human nature, and casinos are designed to appeal to this basic instinct. The precise origin of gambling is unknown, but evidence exists that it has been popular throughout history in nearly every culture around the globe. In modern times, the casino has developed into an enormous industry, generating billions of dollars in annual profits. The largest casino in the world is the WinStar World Casino and Resort in Thackerville, Oklahoma, a tribal gambling facility operated by the Chickasaw Nation, a federally recognized Native American tribe.
The most common way that casinos make their money is by taking a percentage of all money bet on their games. This is called the vigorish or house edge, and it gives the casino an advantage over players that is mathematically determined. Other ways that casinos generate income include the rake, which is the commission taken by the house in games such as blackjack and video poker. Casinos also make money from table games such as baccarat, where the house takes a fixed percentage of the bankroll, and from slot machines, which pay out based on random number generators.
Because of the large amounts of money that are handled within a casino, both patrons and staff may be tempted to cheat or steal. To counter this, most casinos spend a large amount of money and effort on security measures. These range from the simple, such as requiring all players to keep their cards visible at all times, to the elaborate, such as high-tech “eye in the sky” surveillance systems that allow security personnel to watch every table, window and doorway simultaneously.
Many casinos try to lure players with perks such as free hotel rooms, meals and show tickets. These are known as comps, and they are given to frequent visitors or those who spend the most money on games. Some casinos even have a special room where high rollers can play for cash with the most generous rules and maximum bets.
The average casino visitor is a forty-six-year-old woman from a household with above-average income, according to the 2005 National Profile Study by Roper Reports GfK NOP and the U.S. Gaming Panel by TNS. However, the casino business is becoming more diverse as disposable income rises worldwide and people become more adventurous in their spending habits. These changes are expected to increase the global market for casinos.
