A casino is a place where people can gamble on games of chance. Some casinos also offer other entertainment such as stage shows, golf and spa services. People can also eat in restaurants and have drinks. In addition, some casinos have a wide variety of slot machines and gaming tables. The casino industry is a major source of revenue in some countries.

Something about gambling (perhaps the fact that it involves large amounts of money) encourages patrons to cheat and steal. As a result, casinos spend a lot of time and money on security. In addition to cameras, there are often bodyguards on duty. There are also special rules and routines that all players must follow. For example, a player cannot touch his or her cards while the dealer is dealing them.

Most casinos have some type of electronic surveillance system. In addition, many have catwalks in the ceiling that allow surveillance personnel to look down, through one way glass, on the activities at the tables and slot machines. Security staff also watch patrons from booths located throughout the casino floor.

Despite the high level of security, there are still a number of things that can go wrong in a casino. Patrons may try to cheat or steal, either in collusion with other patrons or on their own. In addition, casino employees can be tempted to steal. As a result, there are strict rules and routines that must be followed by both patrons and staff in order to keep the casino safe.
