A Casino is a public place that offers a variety of games of chance and gambling is the primary activity. While musical shows, lighted fountains, shopping centers and lavish hotels help draw in customers, casinos would not exist without the games of chance. Slot machines, blackjack, roulette, poker and craps are just a few of the games that generate billions in profits for casinos every year.

A casino’s employees are trained to look for a variety of things that could indicate cheating or other violations of rules. Security personnel patrol the floor with a view of everything that happens on each table, looking for blatant card markings or dice-switching. They also keep an eye out for betting patterns that might indicate a pattern of stealing money from other players.

Most casinos use chips rather than actual money, which makes it easier for security staff to track players’ movements. Many casinos are decorated with bright, sometimes gaudy colors such as red to create a stimulating and cheering environment that can distract customers from their losses. Some casinos do not even put clocks on their walls because they don’t want gamblers to think about time and the fact that they are losing.

Gambling is believed to have existed for millennia, with primitive protodice and carved six-sided dice found in ancient archaeological sites. But the modern casino as a place where a wide variety of gambling options can be found under one roof did not develop until the 16th century when a gambling craze swept Europe and Italian aristocrats held private parties at places called ridotti (rooms for gambling) that were technically illegal.
