A casino is a place where people can play games of chance for money. It may also offer other types of entertainment, such as shows or food. Many casinos are located in cities with large populations, such as Las Vegas or Atlantic City. Many countries have legalized gambling, but some still prohibit it.
Gambling probably began before recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice found in the oldest archaeological sites. However, the modern casino didn’t develop until the 16th century, when a gambling craze swept Europe. Italian aristocrats would hold private parties at places called ridotti, which were technically illegal but rarely bothered by authorities [Source: Schwartz].
Most casinos have security measures to prevent cheating or theft. A basic requirement is a sign that says, “No one under 21 may play, enter, or loiter in any gambling game, slot machine, race book, sports pool, or pari-mutuel betting area.”
There are also special cameras that watch the casino floor to spot suspicious activity. Often, the security department is divided into two groups: a physical security force and a specialized surveillance team. Physical security patrols the casino and responds to requests for help or reports of alleged criminal activity, while the surveillance team operates the casino’s closed-circuit television system. Both departments work closely together to prevent crime in the casino. They are aided by the fact that most casino games follow certain patterns, making it easier for security to notice anything out of the ordinary.
