What Is a Casino?

A casino is a gambling establishment where patrons can play games of chance. These games include slot machines, poker, blackjack, roulette and craps, among others. Some casinos also feature live entertainment and top-notch hotels and restaurants. Successful casinos bring in billions of dollars each year for the companies, investors and Native American tribes that own and operate them.

A casino can be as small as a single card room or as large as the famous Bellagio in Las Vegas. Despite their differences, all casinos try to give off an air of wealth and exclusivity. Lush carpets and carefully designed lighting are often used to create a moody, luxurious ambiance. It is also important to minimize the sense of time passing, so casinos often do not display clocks and use colors like red that are believed to make people lose track of time.

Due to the high amounts of money involved, casinos are a tempting target for both criminals and ordinary people who might want to cheat or steal. Because of this, most casinos have extensive security measures in place. For example, security cameras watch every table, window and doorway. Security personnel can even adjust cameras to focus on suspicious patrons.

Casinos make their money by charging a small percentage of every bet to the patrons who play the games. This advantage, which can be as low as two percent, adds up over the millions of bets placed each year by casino visitors. This income enables the casinos to build spectacular hotels, fountains and towers, as well as elaborate themes for their gaming rooms.
