Casino is an establishment where people can gamble on games of chance and skill. These places often have many different types of gambling games and amenities, such as dining, entertainment, top-notch hotels, spas, and other attractions for their guests to enjoy. Some of the biggest casinos in the world even have theaters where popular pop, rock, and jazz artists perform.
While the precise origin of gambling is unclear, it is generally believed to have predated recorded history, with primitive protodice (cut knuckle bones) and carved six-sided dice being found in archaeological sites [Source: Schwartz]. The casino as a place where people can find a variety of ways to gamble under one roof didn’t really develop until the 16th century, when a gambling craze swept Europe. Italian aristocrats would gather at “ridotti” to wager on various sports and other events, and these clubs became the ancestor of today’s modern casinos.
Casinos bring in billions of dollars a year for the companies, investors, and Native American tribes that own them, as well as local governments that collect taxes on casino-type gambling. But there is one thing about gambling that should never be overlooked: the math is stacked against the players. The house always wins, and the longer you play, the more likely you will walk out with less money in your wallet than when you walked in.
To counteract this, casinos employ elaborate surveillance systems. For example, many have catwalks over the casino floor that allow security personnel to look down through one-way windows at every table and slot machine. They can also adjust the cameras to focus on suspicious patrons and note how much money each player is winning or losing at a particular game.
