What Is a Casino?

A casino, or gaming hall, is a facility where people can gamble. Casinos are places where the majority of activities take place on tables and slot machines, but a wide variety of games may be available. They can also offer entertainment, such as live music or shows. They can have a themed décor, and are often located in areas of the city that are not well served by other types of recreational facilities.

While gambling likely predates written history, the casino as a place to find a variety of ways to bet under one roof did not develop until the 16th century. A gambling craze was then sweeping Europe, and wealthy Italian nobles would hold parties known as ridotti to satisfy their urges. Technically illegal, the ridotti were frequented by members of the nobility and well-to-do citizens.

Because of the large amounts of money handled, casinos are often the subject of attempts to cheat and steal by patrons and employees in collusion or independently. For this reason, many casinos have security measures in place to prevent such activity. Security cameras are commonly used to monitor all parts of a casino, and bright (and sometimes gaudy) floor and wall coverings have been chosen for their stimulating and cheering effects; red is particularly effective in this regard.

In order to maximize their profits, casinos regularly offer lavish inducements to big bettors, who are called “high rollers.” These might include free spectacular entertainment, luxury living quarters, reduced-fare transportation and even hotel rooms. High rollers are also given special attention by casino security staff, who are trained to recognize suspicious behavior.
