A casino is an establishment for certain types of gambling. It offers a variety of games of chance and in some cases, skill, that allow patrons to gamble for cash or other items of value, such as food and drinks. Most casinos are operated by governments or private businesses. Some are part of a larger complex that features hotels, restaurants, retail shops, or cruise ships. Others stand alone. Some casinos specialize in particular types of gambling, such as poker or roulette.

In addition to gaming, some casinos are known for their live entertainment and other amenities. For instance, the MGM Grand on the Las Vegas Strip is a popular destination for those who enjoy watching sports on its 60 large plasma televisions. The resort is also well-known for its world-class spa and dining options. It was even featured in the 2001 movie Ocean’s Eleven.

The precise origin of gambling is unknown, but it is widely believed that it has been practiced in some form or another throughout history. Many ancient societies engaged in it, including the Mesopotamian city of Susa, the Greek and Roman empires, and Napoleon’s France.

Casinos are regulated by government bodies to ensure fair play and the safety of patrons. They must comply with strict rules and regulations, which usually include requiring guests to be of legal age to enter. In most countries, the minimum age for gambling is set at 21. Patrons may exchange money for chips to play casino games, but they cannot win more than the casino can afford to lose. This is because most casino games have a mathematical expectancy that guarantees the house will make a profit.
