A casino is a place where people gamble. It’s also a place where people come to drink, dance and watch entertainment. Casinos provide billions of dollars in profits for their owners every year. But how do casinos make that money? This article will explore the history of casinos, the games they offer and how they stay in business.

Although musical shows, lighted fountains and shopping centers attract visitors, a casino’s profits really stem from gambling. Slot machines, blackjack, roulette, poker and baccarat bring in the big bucks. Some casinos specialize in a particular type of gambling, such as horse racing or dice.

Because of the large amounts of money involved, casinos have a variety of security measures in place. The most basic measure is a system of cameras located throughout the casino. These “eyes in the sky” can be manipulated by security workers to focus on specific patrons who may be cheating or stealing. Casino staffers also have a closer look at the game tables, watching for blatant cheating such as palming or marking cards and dice. Table managers and pit bosses monitor the action at each table, looking for betting patterns that indicate suspicious behavior.

Because every game in a casino has an expected value, it is virtually impossible for a casino to lose money. This virtual guarantee of profit allows casinos to offer big bettors extravagant inducements such as free spectacular entertainment, luxurious living quarters, reduced-fare transportation and other perks.
