When the word casino is used, many people think of a Las Vegas megaresort, a huge entertainment complex ablaze with neon lights and fun. Although that is a common perception, the term actually describes any building or room in which gambling is conducted. Merriam-Webster defines a casino as a “place of social amusements, especially gambling and drinking.”

In the United States, casinos are usually located in cities with substantial tourist traffic, and they are frequently operated by large hotel-resort corporations. In Europe, casinos are often located in areas renowned for their beauty or leisure activities, such as Cannes, Nice, and Divonne-les-Bains in France, and Monte Carlo in Monaco.

The games played in a casino are usually games of chance, such as roulette and blackjack. The mathematical odds are always against game players in the long run. Even so, a casino must make money in order to remain profitable. This is why it is necessary for most casino gamblers to set loss limits and to keep their losses to a minimum.

In addition to the obvious security measures, some casinos employ specialized technological monitoring systems. These include video cameras, a system called “chip tracking,” which allows casino surveillance personnel to oversee betting chips minute-by-minute and to monitor for any statistical deviation from the expected results of a game, and computerized roulette wheels.

Surveys indicate that the majority of casino patrons are male, forty-five years old, and have above-average incomes. The majority of respondents also go to the casino with friends or family members, and many of them enjoy gambling as a “fun night out.” In 2005, a study for Harrah’s Entertainment indicated that the average casino gambler was a forty-six-year-old female with an above-average household income and who preferred slot machines to all other games.
