A casino is a facility for certain types of gambling. In the most common usage, it refers to a room or building in which a variety of gambling activities take place, but the term may also refer to an entire complex of gaming facilities. Casinos are often combined with hotels, resorts, restaurants, retail shops, and cruise ships. They are known for their intense concentration of game play and the large amounts of money that can be won or lost by players.

While musical shows, lighted fountains and shopping centers help attract the eye, casinos would not exist without the games of chance that provide the billions in profits raked in every year. Slot machines, blackjack, roulette, baccarat, craps and more are the games that make up the modern casino industry, but they are not the only ones.

Gambling almost certainly predates recorded history, with primitive protodice and carved six-sided dice among the oldest archaeological finds. But the idea of a place to find a variety of ways to gamble under one roof did not develop until the 16th century, when the European gambling craze reached its peak in Italy with a series of private clubs called ridotti.

By the 1970s, Nevada was attracting huge numbers of tourists seeking a high-stakes, glamorous casino experience, and casinos were proliferating all over the world. Today, the biggest casino in the world is in Macao, a former Portuguese colony, with a massive complex that includes a replica of the city’s Venetian canals.
