What Is a Casino?


A casino is a place where people can gamble and play games of chance. Casinos can be massive gambling resorts such as the Strip in Las Vegas, or they can be small card rooms in bars or even in racetracks. People visit casinos to play a wide range of games, from poker and blackjack to roulette and craps. Some games are based on skill, but most are pure luck. The house always has an advantage in these games, and the amount of money that a player will lose on average is known as the house edge.

Casinos make billions of dollars each year from the millions of people who visit them every year. While music shows, shopping malls and elaborate hotels help draw in the crowds, the bulk of the profits come from gambling. Slot machines, table games such as baccarat and blackjack, and dice games such as craps all contribute to the enormous profits that casinos generate each year.

While there is no universal definition of a casino, the term usually refers to a building where people can gamble and play games of chance. The word is derived from the Latin cazino, which means “small box.” The first modern casino was built in Monte-Carlo, Monaco, in 1863.

The modern casino industry is global in scope and has expanded to include locations throughout the world. Many of these casinos are located in large cities with easy access to international flights, and many have hotels and other facilities for visitors. In addition to their gambling operations, many casinos host concerts and other entertainment events.

Security is a major concern in any casino, and it starts on the floor. Casino employees are trained to watch for blatant cheating such as palming, marking, or switching cards and dice. Pit bosses and managers oversee the table games, while supervisors keep an eye on the entire casino floor to spot patterns in betting that may indicate a foul play.

Aside from a trained staff, casinos also employ a variety of technological methods to ensure the safety of their patrons. In addition to cameras and other surveillance equipment, some casinos have special chips with built-in microcircuitry that interact with electronic systems at the tables to monitor the amounts bet minute-by-minute and warn if any deviation from expected results occurs. Roulette wheels are electronically monitored for anomalies, as are video-game machines.

While the glitz and glamour of casinos draw in millions of visitors each year, they can also be dangerous places. Mafia members have been known to control whole casinos, and organized crime figures often use their own money to fund casino operations. This has given the industry a seamy image that has made legitimate businessmen reluctant to invest in it.
