A casino, or gaming house, is a place where people can find a variety of ways to gamble under one roof. Modern casinos add luxuries like restaurants, stage shows and dramatic scenery to lure patrons, but the vast majority of their profits come from gambling activities.
Gambling almost certainly predates recorded history, with primitive proto-dice and carved six-sided dice found in many archaeological sites. But the concept of a casino as a central hub for multiple types of gambling did not emerge until the 16th century, when a gambling craze swept Europe and Italian aristocrats created private social clubs known as ridotti to enjoy games such as roulette, blackjack and craps. These clubs were often operated by mobsters, and federal crackdowns on mob involvement in casinos have kept them away from most legitimate gambling businesses.
Every game offered at a casino has a mathematical expectancy, and it is very rare for a casino to lose money. To help ensure their financial integrity, casinos employ mathematicians who track the house edge and variance for each game and make adjustments to keep their profit margins as high as possible.
The modern casino is a multi-million dollar business, and the glitzy mega-resorts of Las Vegas, Macau and other destinations are renowned for their splendor. But a casino isn’t just a glamorous facade: it’s a complex operation that includes everything from security and maintenance to the design of the interior spaces. This article takes a closer look at how casinos make their money, what kinds of games are played and why some are more popular than others. It also looks at how casinos stay safe and the dark side of their business.
