A casino or gambling house is an establishment that offers a variety of gaming activities. It may also offer food and drink, entertainment, and other amenities to its patrons. In the United States, casinos are regulated by state and local laws. Many of these establishments are associated with hotels and resorts, or they may be standalone.

The precise origin of casino is uncertain. There are various theories, though most agree that it began in ancient Mesopotamia and Egypt. Gambling games were later popular in Europe during the middle ages, and during the reign of the Tudor monarchs, they became more widespread. In modern times, casino has become one of the most popular forms of entertainment in the world.

Most states regulate casino gambling, although the specific regulations vary. Some allow only certain types of games, and some require players to be 21 years old. In addition, some casinos are operated by tribes and allow players from other states. In addition, some state-regulated online casinos are available.
