What is a Casino?

A casino is a place where people can play gambling games. These are usually noisy and colorful, with a variety of games. They often have bars, restaurants, non-gambling games rooms, swimming pools and spas. Some are enormous, with impressive decor and a mindboggling number of games.

Gambling probably predates recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice being found in ancient archaeological sites. However, the casino as a central venue for a wide range of gambling activities did not develop until the 16th century when a gambling craze swept Europe and Italian aristocrats created social clubs known as ridotti where they could gamble without being bothered by legal authorities.

Modern casinos use sophisticated security systems to prevent cheating and stealing. For example, slot machines have built-in microcircuitry that enables casinos to supervise the exact amounts bet minute by minute and quickly discover any anomaly; roulette wheels are electronically monitored to ensure they match up with expected statistical results. Casinos also employ security cameras throughout the facility to provide a “eye in the sky” view of the entire casino floor.

While casinos are lucrative enterprises, they also generate significant losses due to compulsive gambling. Studies show that problem gamblers generate a disproportionate share of casino profits, and the economic costs of treatment and lost worker productivity offset any gambling revenue gains. As a result, the net effect of casinos on a community is often negative. Nevertheless, many cities around the world host casinos.
