Casinos are public places where people can play games of chance. They also offer a variety of other activities. Many casinos are attached to restaurants, shopping centers and other types of entertainment venues.

In the United States, there are three main types of casinos. There are land-based casinos, riverboat casinos, and casinos on American Indian reservations. The latter two are not regulated by state antigambling laws.

Typical casinos feature lavish decor. Floor coverings are carefully chosen, and lighting is often dimmed to create a sense of excitement. People can also be offered free cigarettes and beverages.

There are also many types of entertainment at casinos, including circus troops, stand-up comedians, and music stars. A number of casinos are owned by the Hilton hotel company.

Gambling is the primary activity at most casinos. High rollers often receive luxury suites and other incentives.

A casino can make a lot of money from high-stakes gamblers. For example, in 2003, Megabucks slot machine paid out $39.7 million.

High rollers can get comps worth thousands of dollars. These are based on length of stay and stakes played.

Casinos also offer free meals and drinks to gamblers. In addition, casinos may offer reduced-fare transportation to big bettors.

Most casinos are staffed with security. Security includes surveillance cameras that watch every window and door. Video feeds are recorded and reviewed later.

Gaming analysts are hired by casinos to perform gaming analysis. This helps casinos determine what their house edge is.
