A casino is a place where people play games of chance and, in some cases, skill. The term can refer to a large, luxurious gambling establishment like the Bellagio in Las Vegas or to a smaller card room at a local bar. Casinos attract a mix of customers, from casual players to high rollers. They may offer free drinks, stage shows and other amenities to attract customers. They also make a profit from the bets that people place on games of chance. Casinos are a huge business, bringing in billions of dollars each year for the owners, investors, state and local governments and Native American tribes.
The precise origin of casinos is not known, but they have been around for centuries. They were first popular in Europe, where they were established as social clubs for the elite and upper class. As gambling became more widespread, they began to spread to other parts of the world and today there are casinos in every continent.
In the United States, the popularity of casinos grew as the country moved away from prohibition and organized crime figures saw an opportunity to make money from legal gambling. Mob money flowed into Reno and Las Vegas and gangsters took control of some casinos, taking sole or partial ownership and manipulating the outcomes of games. Later, real estate investors and hotel chains realized the potential of casino businesses, and they bought out the mobsters. In modern times, the mobsters are mostly out of the picture, and federal crackdowns and the threat of losing a gaming license at even the slightest hint of mob involvement ensure that legitimate businesspeople run casinos without any Mafia interference.
