A casino is a place where gambling games can be played. It can also house restaurant and stage shows. Modern casinos have become much more than that, adding all kinds of luxuries to draw in customers and keep them there. Some of these luxuries include free food, drinks and even limo service. However, the biggest attraction is the gambling. Slot machines, roulette, blackjack, craps and keno make up the bulk of a casino’s profits.

The history of gambling dates back to the earliest days of civilization. Primitive proto-dice and carved six-sided dice are found in many archaeological sites, but the casino as we know it today did not emerge until the 16th century when a gambling craze swept Europe. During this time, Italian aristocrats often held private parties in places called ridotti. While these were technically illegal, they were often not bothered by authorities.

Gambling in its various forms has always been popular. It is believed that the earliest casinos were small clubs for members only, where people would gather to play cards and other gambling games. Today’s modern casino is more like an indoor amusement park for adults and is a major source of revenue for cities and states.

Security at a casino is usually handled by two departments. The physical security force patrols the casino and responds to calls for assistance or reports of definite criminal activity. The specialized surveillance department operates the casino’s closed circuit television system, which is commonly known as the eye in the sky.
