What Is a Casino?


A casino is a gambling establishment that houses a variety of games of chance and some skill, where patrons place bets against the house. Casinos add to this definition a wide range of amenities, from restaurants and stage shows to free drinks and elegant living quarters. Some of the world’s largest casinos offer a full range of games and entertainment, but some are more focused on specific types of gambling or regions of the world.

The precise history of casino gambling is unknown, but it seems to predate recorded history – primitive protodice and carved six-sided dice have been found in archaeological sites. The modern idea of a casino began to develop in the 16th century, when European gamblers became aware that they could find a wide variety of gambling games under one roof. The word casino probably derives from the Italian ridotto, a private clubhouse for wealthy socialites and noblemen that was favored during the gambling craze of the period.

Today’s casinos have a broad international appeal and are regulated in most countries. They are largely owned by large corporations or hotel chains, which have deep pockets and don’t want mob interference in their business.

Most casinos use a variety of technological measures to ensure security and fair play. Video cameras record all activities, and specialized computers monitor the activity of individual players to detect cheating or collusion. Roulette wheels are electronically monitored minute by minute, and computer algorithms can quickly discover any deviation from expected results.
