Casino is a movie about gambling and the people who play games of chance. It shows how a casino can be the center of an elaborate web of corruption that involves mob figures, unions, politicians, and even the Chicago mafia. It is also about the psychology of gaming. The film focuses on the reasons why people gamble and the psychological aspects that keep them playing.

Initially, the only place to gamble legally was in Nevada. But as other states legalized gambling, the booming industry spread across the United States and beyond. Almost every major city now has a casino. Casinos are often combined with hotels, resorts, restaurants, shopping, and other tourist attractions. Some have a unique theme, such as an old Western town or the Orient.

Most casinos employ security systems to protect the patrons and property. Cameras in the ceiling provide a high-tech “eye-in-the-sky” that can monitor every table, window, and doorway simultaneously. The computers in the system can be adjusted to zoom in on suspicious behavior. Casinos also have a variety of other surveillance technology, including chip tracking and electronic monitoring of roulette wheels to discover any statistical anomalies.

In 2005, Harrah’s Entertainment reported that the typical casino patron was a forty-six-year-old female with a household income above the national average. These adults are more likely to have vacation time and available spending money than younger adults. They are also more apt to be interested in the entertainment options at a casino, and thus more likely to be swayed by promotions.
