What Is a Casino?

A casino is a place where customers gamble by playing games of chance, in some cases with an element of skill. The most popular of these games include blackjack, roulette, baccarat, and video poker. Most games have mathematically determined odds that give the house an advantage over the players, which is referred to as the “house edge”. Some casinos offer complimentary items to players, such as drinks or food, while others charge an hourly rate for play.

Modern casinos are like indoor amusement parks for adults, offering a variety of entertainment and profits for the owners. Musical shows, lighted fountains and elaborate theme buildings draw in the crowds. But a casino’s true attraction is gambling, and the billions of dollars in profits that are made each year by games such as slots, craps, blackjack, and roulette come from gambling revenue.

Casinos are designed to encourage gambling by providing a variety of attractive machines and games and by offering complimentary items to high rollers. These promotions are called comps. They may also include free hotel rooms, dinners, show tickets, or even limo service and airline tickets. Casinos may employ people to manage these promotional activities, but most casinos outsource this work to companies specializing in gaming analysis.

Casino security is usually divided between a physical security force that patrols the premises and a specialized department that operates the casino’s closed circuit television system, often referred to as the “eye in the sky”. Because large amounts of money are handled within a casino, both patrons and employees may be tempted to cheat or steal, either in collusion or independently. For this reason, most casinos have sophisticated surveillance systems.
