A casino is a building where people can gamble and play games of chance. It is common for casinos to offer food and drink, and to provide entertainment, such as concerts, comedy shows, and gambling demonstrations. A casino is an important source of revenue for many communities, and it can create jobs. But it is also important to recognize that problem gambling can have serious consequences for the health of individuals and their families, as well as the local economy.

The concept of a modern casino originated in Europe in the 16th century, with private clubs for European aristocrats called ridotti [Source: Schwartz]. These venues provided an opportunity to enjoy a wide variety of games under one roof and were often used to celebrate special occasions. Since then, they have become widely available around the world. Casinos have a reputation for being places where players can risk large amounts of money, and are sometimes associated with organized crime. However, they are usually very safe places to visit, thanks to extensive security measures.

In addition to a physical security force, most casinos have a specialized surveillance department that uses closed circuit television to watch the activities of the floor and table games. The casino industry has developed a number of other security methods, including catwalks that allow surveillance personnel to look down through one-way glass on the patrons at the tables and slots. These measures are designed to prevent cheating by patrons and employees, either in collusion or independently.
