A casino is a place where people can gamble and play games of chance. They may also offer other entertainment such as shows and restaurants. Casinos usually have strict security measures because they handle large amounts of money. They use cameras throughout the facility to monitor activities and prevent theft. They also employ trained staff to prevent cheating and other forms of fraud.

Something about gambling (perhaps the presence of so much cash) encourages patrons to try to cheat or steal, either in collusion with other players or independently; therefore casinos spend a great deal of time and effort on security. Security personnel are on duty around the clock and watch over every table, game, and slot machine. Casinos also make extensive use of technology to supervise their gaming operations: chips have built-in microcircuitry that allows casinos to track the exact amount wagered minute by minute; roulette wheels are electronically monitored to discover any statistical deviation from expected performance; and video cameras record everything that occurs inside the casino, both on and off the casino floor.

While a casino might be famous for its fountain show, luxurious hotels, and elaborate theme, it can’t survive without its main attraction: gambling. Slot machines, blackjack, poker, roulette, and other games of chance provide the billions in profits raked in by casinos each year. This article takes a look at the history and culture behind some of the world’s most famous casinos, from the Bellagio in Las Vegas to Monte Carlo, Monaco.
