Casino is a place where gambling games are played. While casinos add a host of luxuries like shopping centers, music and stage shows to help draw in patrons, they are essentially places where the game of chance rules the day. Slot machines, blackjack, baccarat, roulette and other popular games provide the billions of dollars in profits raked in by casinos every year.

While gambling probably began long before recorded history, the modern casino is a fairly recent development. Its origin can be traced to Atlantic City in 1978, and it has since spread throughout the United States. Casinos are also found in many countries abroad. In the US, the bulk of the casinos are located in Nevada and on American Indian reservations. The latter are not subject to state anti-gambling laws.

The casinos are financed by the money from bettors, who in turn pay a fee to play. While the fee is not large, it is enough to earn the casinos a significant profit. In addition to this, every game that is offered in a casino has a built in advantage for the house. This advantage, which is called the house edge, can be very small but it is enough to give the casinos a virtual guarantee of gross profits.

The casino business is often dirty and risky, with crooks trying to steal cash from patrons or from one another. Because of this, security is a high priority at most casinos.
