A casino is an establishment for gambling. It is often combined with hotels, restaurants, retail shops, and other entertainment facilities. Some casinos are operated by government-owned businesses. Others are owned and operated by private individuals or corporations. The size and scope of a casino is defined by its legal framework, and may be limited to a specific gaming floor or a large building housing several such floors, as well as a number of bars and restaurants. Some casinos are also known for hosting live entertainment.
The word casino comes from Italian gambiarra, meaning “to play at cards” or “gambling house.” Gambling probably predates recorded history, with primitive protodice like astragali and carved six-sided dice among the oldest archaeological finds. The modern casino as a collection of ways to gamble under one roof did not develop until the 16th century, when a gambling craze swept Europe and wealthy Italian aristocrats used private venues called ridotti to host parties where they could play the latest games and socialize with their friends.
Most of the largest casinos are located in tourist destinations, such as Las Vegas, which has gained worldwide fame for its gambling and nightlife. In addition to a vast array of tables and slot machines, the city offers many other attractions to visitors, including shopping, restaurants, shows, and architectural marvels. The list below contains some of the largest casinos in the world, as well as some lesser-known but equally impressive venues that have earned their place on this list thanks to their sheer scale and the awe-inspiring experience they offer.
