A casino is a public place where a variety of games of chance can be played and gambling is the primary activity. Often casinos add many luxuries to help attract and keep customers such as restaurants, free drinks, stage shows and dramatic scenery. However, even simpler places that house gambling activities can be called casinos.

Because of the huge amounts of money handled by casino staff and patrons, it is not uncommon for people to try to cheat or steal from each other or the establishment. For this reason, most casinos employ a number of security measures to prevent this. Some are as simple as security cameras throughout the facility. Others are more elaborate such as the “eye-in-the-sky” systems that use catwalks in the ceiling to allow surveillance personnel to look down through one way glass at every table, window and doorway in a casino.

Casinos are big business and make billions of dollars each year for the companies, individuals, investors and Native American tribes that own them. They also bring in millions of dollars for state and local governments that regulate them.

Casinos earn most of their revenue from the vig, or rake, that is taken from each bet placed on a game. This rake can vary between two percent and as much as fifteen percent. This profit, along with other revenues, is how a casino makes money and keeps it in business. Some casinos also earn additional profits from special services to large bettors such as free spectacular entertainment, reduced-fare transportation and hotel rooms.
