A casino is a public place where a variety of games of chance are played. In addition to offering gambling, a casino often offers restaurants, stage shows and other entertainment. It is also home to a number of high-stakes gamblers, who can earn the casinos substantial comps, including free luxury suites and meals.

Gambling probably predates recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice found in ancient archaeological sites. However, the modern casino as a place to find a wide variety of ways to gamble under one roof did not develop until the 16th century. During this time, a gambling craze swept Europe and Italian aristocrats met in private places called ridotti to gamble and socialize. These places were technically illegal, but the gamblers rarely had their activities impeded by law enforcement.

While some people enjoy gambling, others view it as a waste of money. The average American adult spends about five hours per week on gambling, according to a 2005 study by Roper Reports GfK NOP and TNS. The majority of those who play are women over forty-five with above-average incomes.

Despite their lavish appearances, casinos are designed to slowly bleed patrons of cash. They employ a variety of techniques to deceive players, including bright, sometimes gaudy floor and wall coverings to entice gamblers and the use of red, which is thought to cause people to lose track of time. In order to monitor their operations, casinos use cameras and computer systems to track player movements and betting patterns.
