A Casino is a building or room where gambling games are played. It’s also an entertainment venue, offering stage shows, restaurants and more. The casino industry has a reputation for being illegal, but there are many legitimate operations. The casino industry is a multibillion-dollar business, and it contributes to the economy in many ways. Casinos are often located in major cities or on Native American reservations, and they provide a variety of jobs for local residents.

Gambling probably predates recorded history, with primitive protodice such as cut knuckle bones and even carved six-sided dice found in archaeological sites [Source: Schwartz]. The idea of a casino, a place where patrons could find many forms of gambling under one roof, did not develop until the 16th century. It became popular as the craze swept Europe, and Italian aristocrats gathered in private clubs called ridotti to gamble, drink and socialize. These venues were technically illegal, but they were rarely bothered by authorities.

Modern casinos are governed by strict rules and regulations to ensure the safety of their patrons and the integrity of their games. They have a security force and a specialized surveillance department that monitors closed circuit television (CCTV) footage of their facilities. In addition to cameras, most casinos have security officers patrolling the premises and responding to calls for assistance or reports of suspicious activity. This type of security is primarily for the benefit of the patrons and has been very successful in preventing crime within casinos.
