A Casino is a gambling establishment offering a variety of games for public wagering. Gambling likely predates recorded history, with primitive protodice and carved six-sided dice found in some of the oldest archaeological sites. The modern casino, however, developed in the 16th century during a gambling craze in Europe that saw many wealthy Italian nobles meet in secret rooms known as ridotti to gamble and socialize [Source: Schwartz].

Regardless of their size or location, all casinos are designed to generate the most revenue possible from a given number of visitors. To this end, they feature high-tech surveillance systems, security staff armed with pepper spray and metal detectors, and the types of crowd control measures used by theme parks (e.g., fences and velvet ropes). In addition to gambling, some casinos offer food, drinks, entertainment, and lodging.

As a result of their high profits, casinos are a favorite target for criminal activity. Patrons and employees may try to cheat or steal, either in collusion or independently. Several states have laws to prevent this, but most casinos rely on a combination of physical and technological security measures.

The most famous casino in the world is probably the Bellagio in Las Vegas, which is known for its spectacular fountain show and luxury accommodations. Caesars Palace on the Strip is another famous example, with its Roman-inspired architecture and celebrity performers including Frank Sinatra, Liberace, Elton John, and Dolly Parton. These casinos draw large numbers of tourists from around the world.
