What Is a Casino?

A casino is a building or room in which people can gamble and play games of chance. It has a very long history and is associated with organized crime. Historically, many casinos were run by mafia families, and their money provided the capital to build elaborate facilities with a range of entertainment options.

Today, casinos are regulated and most have a wide variety of games. In the United States, there are over 1,000 casinos. Many of these casinos are located in Nevada, but some are also found in other states including Iowa, New Jersey, and Atlantic City. Many casinos also offer gambling on Native American reservations.

Because large amounts of money are handled within a casino, security is a very important issue. There are numerous measures used to prevent cheating and stealing by both patrons and staff members. These include the use of cameras, which are usually well placed throughout the casino to provide surveillance on all activities and have the ability to be focused on specific areas by security personnel working in a separate control room (often called an eye in the sky).

Most casinos also employ a physical security force as well as a specialized surveillance department. These are normally coordinated and work together to ensure the safety of both guests and property. Some casinos have catwalks built into the ceiling, which allow surveillance personnel to look down on tables and slot machines from above. This allows them to quickly spot any suspicious activity and deal with it swiftly.
