A casino is a place where gambling games are played. It may have extra features such as restaurants, free drinks and stage shows, but at its core, a casino is a place where people can gamble for money.
A modern casino often has an elaborate surveillance system, known in the industry as a “eye in the sky”. Cameras are usually mounted on the ceiling and can be adjusted to focus on specific patrons by security workers in a separate room filled with banks of security monitors. This technology has significantly reduced crime and cheating in the modern casino.
Casinos are also equipped with other technological devices to monitor gaming activity, such as chip tracking systems that allow them to know exactly how much is being wagered on a given table minute by minute. Roulette wheels are electronically monitored to discover any statistical deviation from expected results; and in table games like blackjack and baccarat, the decks of cards are electronically monitored for any anomalies that could indicate cheating.
Gambling in its various forms has been around for millennia, with archeological evidence of wooden blocks used in games of chance dating to 2300 BC and dice appearing in Rome as early as 500 AD. While the casino as a commercial enterprise probably only came into existence in the late 19th century, it has since grown to become one of the most profitable businesses in the world. This article will explore the history of casinos, the most popular games they offer and how they make their billions in profit every year.
