A casino is a facility for gambling. In the United States, most casinos are located in Las Vegas (which alone accounts for about 40 percent of Nevada’s tax revenue), while others operate on American Indian reservations and in Atlantic City. A smaller number are also found in riverboats and at racetracks, while some states have banned casino gaming altogether.

Like all businesses, casinos must deal with the potential for cheating and theft by both patrons and employees. As such, modern casinos have a variety of security measures to deter these activities. These can include a physical security force that patrols the premises, as well as specialized surveillance departments. Additionally, most casinos have security cameras throughout the facility.

Because of the large amount of money handled within a casino, both patrons and staff may be tempted to cheat or steal. For this reason, most casinos have extensive security measures to deter these activities. These include a physical security force that patrols and responds to reports of suspicious or definite criminal activity, as well as specialized surveillance departments that use closed circuit television to monitor the casino’s internal operations.

Some casinos, particularly those located in the United States, have been accused of a lack of fairness in their games and an overall untrustworthy environment. These accusations have led to calls for a more regulated industry. In response, some states have established independent regulatory bodies for casinos, while others have formed casino associations that advocate on behalf of the industry.
