A casino is a gambling establishment that offers a wide range of games of chance. It also has entertainment options such as live performances, stage shows and other luxuries to attract visitors. Casinos are generally combined with hotels, resorts, restaurants and retail shops in one complex. The word is derived from the Latin “caino”, meaning ‘gambling house.”
Gambling in its various forms has been part of human society for millennia. Archeological evidence of dice dates back to 2300 BC in China, and card playing appeared in Europe around 500 AD. Today, casinos are highly regulated and offer a variety of different games. The most popular are slot machines, poker, blackjack and roulette.
Casinos make money by introducing a mathematical advantage into each game. This edge can be very small, but over millions of bets it earns the casino a substantial profit, which it passes on to patrons through comps and other inducements. In games with an element of skill, like blackjack and video poker, the casino gains money through a commission called the rake.
Modern casinos are usually protected by a combination of physical and specialized security forces. Dedicated surveillance departments monitor the casino’s closed circuit television system, and physical security guards patrol the premises to respond to requests for assistance and reports of suspicious or definite criminal activity. They are trained to observe the routines of casino guests and recognize when something is amiss. Observational skills are particularly important for casino security, because windows and clocks are rare in casinos, so players can lose track of how much time has passed.
