What Is a Casino?


A casino is a gambling establishment that offers various forms of entertainment based on chance. These include slot machines, roulette, blackjack and poker. Casinos can be found in many countries, including the United States. Most casinos are located in cities with a long history of gambling, such as Las Vegas and Atlantic City.

Modern casinos are like indoor amusement parks for adults, with elaborate hotels, shopping centers and lighted fountains to draw in visitors. The vast majority of the fun, however, is derived from games of chance. Slots, blackjack, baccarat, craps and roulette are among the most popular casino games and provide billions in profits to casinos each year.

The games are supervised by security people who keep their eyes on everyone in the casino, looking for blatant cheating such as palming, marking or switching cards or dice. Security staff also monitor betting patterns, noting when a patron changes his or her bet from the expected pattern. In addition, a high-tech “eye-in-the-sky” system monitors the entire casino floor and can be adjusted to focus on suspicious patrons by security personnel in a separate room filled with banks of security cameras.

Although the precise origin of casino gambling is unknown, it is clear that some form of it has been around for centuries. While legal casino gambling is now a worldwide phenomenon, it began in the United States when Nevada allowed it. Other states soon followed, allowing a variety of types of casinos, including riverboats, pari-mutuel wagering and Native American gaming facilities.
