A casino (or casin) is a building or room where gambling games are played. The term is also used for the governing body that regulates and licenses such establishments. The term is a portmanteau of two Italian words, referring to a small country villa or summer house (cassino) and a public gaming hall (casino).

Gambling casinos are often located in or near large cities and are highly visible places with distinctive architecture, lighting and signage. They are designed to attract customers from a wide geographic area, and many have special features to appeal to specific market segments. In the United States, there are more than 1,000 casinos. Most are operated by commercial or tribal organizations, and most accept major credit cards. A smaller number are run by state governments, and all offer a variety of games.

The most prestigious casinos combine high stakes with exceptional luxury. From Vegas to Macau, the best casino resorts feature opulent suites, spas and fine dining, alongside the usual range of game tables and slot machines.

The biggest land-based casino in the world is Winstar World Casino in Oklahoma, home of Woody Guthrie and chicken fried steak. However, it isn’t actually the biggest by square footage; this honour goes to the Venetian Macau in Asia. This massive gaming palace packs more than 546,000 square feet of floor space with table games, a canal and gondolas, 350 shops, a live arena and Michelin-starred restaurants.
