Casino is a gambling establishment that offers gamblers the opportunity to win money by playing games of chance. In the United States, casinos are regulated by state laws and are operated by large, diversified business organizations. Many casino employees are skilled at customer service and are trained to provide a positive gaming experience.

For most of America’s history, gambling was illegal. However, this did not stop organized crime gangsters from running casinos in cities such as Reno and Las Vegas. Mob money provided the initial capital needed to make these establishments profitable, but as time went on they became too involved in gambling’s seamy image to be legitimate businesses. This eventually caused the mobsters to lose interest in the casinos and they were bought out by real estate developers and hotel chains that realized what lucrative cash cows casinos could be.

A casino’s profits are derived from a built in mathematical advantage over the bettors that play their games. This advantage can be as little as two percent, but it adds up quickly over millions of bets placed by patrons. Because of this, casinos are virtually assured of a gross profit and therefore are free to offer extravagant inducements to big bettors, such as luxurious living quarters, reduced-fare transportation, and tickets to shows or sporting events.

Modern casinos also employ an extensive security system. This often includes a physical security force and a specialized surveillance department. The latter uses banks of security cameras that can be adjusted to focus on suspicious or definite criminal activity. These systems are usually monitored by security workers in a room known as the eye-in-the-sky.
