What is a Casino?
A casino is a gambling establishment where a variety of games of chance can be played. A casino might include a number of other entertainment features, such as restaurants and free drinks, stage shows and dramatic scenery, but casinos would not exist without the billions of dollars that patrons spend there on games of chance like slot machines, roulette, blackjack, craps, poker, baccarat and keno.
The precise origin of gambling is unknown, but it is believed that it has existed for thousands of years. Primitive protodice (cut knuckle bones) and carved six-sided dice have been discovered at archeological sites, but the modern casino was not developed until the 16th century during a gambling craze that saw Italian aristocrats hold parties in places known as ridotti.
While there are many types of games that can be found at a casino, most are based on the principle that the house always wins. This is because a casino’s owners have a built-in advantage, known as the “house edge,” that ensures that it will always make money on all games played by its customers. The longer a player gambles, the more likely his or her chances are to match up with the house edge and result in a loss of money.
Today, the casino has become a global phenomenon. Almost all countries now permit gambling, and large casinos are built in many cities around the world. In the United States, casinos have been legalized in Atlantic City, New Jersey; on American Indian reservations; and, since the 1980s, in other locations that are exempt from state anti-gambling statutes.
