How Casinos Make Their Money, History of Gambling and Other Interesting Casino Facts


A casino is a place where people can gamble and play games of chance. It can be as fancy or as plain as you like, but the bottom line is that it’s a money-making business for the owners. The modern casino looks more like an indoor amusement park for adults, with musical shows, lighted fountains and shopping centers to attract visitors, but it would not exist without games of chance, which generate the billions in profits that casinos bring in every year. In this article, we’ll explore how casinos make their money, the history of gambling, how to play popular casino games and other interesting casino facts.

How casinos make their money

A major source of revenue for a casino comes from the games themselves, but they must pay out winning bets within an established limit, or risk running out of money. To avoid this, they often have a built in advantage, or “house edge,” which can be small — usually less than two percent – but over time it can add up to millions of dollars. The casino houses this money in special accounts, and pays out winning bets with the house’s money.

How casinos stay safe

A modern casino has a dedicated physical security force and a specialized surveillance department that uses closed circuit television, known as an “eye in the sky” system, to monitor the casino floor. Security staff can see everything happening on the casino floor through the cameras, and can adjust the cameras to focus on specific patrons or activities.
