What is a Casino?


A casino is a gambling establishment, often in an elegant building, where patrons can play games of chance for money. Most casinos are located in cities with a high population of people who like to gamble. A casino’s customers may be tourists from other areas of the country or the world, or locals who like to spend their leisure time gambling and socializing with friends.

Casinos earn their money by taking advantage of the statistical edge that comes with every game offered. This advantage can be as low as two percent, but it adds up over the millions of bets placed each year by casino patrons. This is how casinos make enough money to build elaborate hotels, fountains, giant pyramids and towers, and replicas of famous landmarks.

The large amount of money handled in casinos makes them vulnerable to cheating and stealing, either in collusion with staff or by patrons themselves. To combat this, most casinos have sophisticated security measures. Elaborate cameras offer an eye-in-the-sky view of the entire casino, and can be adjusted to focus on suspicious patrons. Betting chips have built-in microcircuitry to track the amount of money wagered minute by minute; roulette wheels are electronically monitored to discover any deviations from their expected statistical results.

While it is not certain what made the first casinos popular, the idea of using random chance to win large sums of money has been around for centuries. Some historians believe that casinos grew out of ancient Mesopotamia, and others that they originated in the Roman Empire or Napoleon’s France. In America, most casino gamblers are middle-class to upper-class people who like to relax by playing games of chance. They tend to be female, over forty-five, and come from households with above-average incomes. They usually visit a casino at least once a month.
