A casino, or gambling house, is an establishment where people can gamble on various games of chance. These games may include slot machines, table games (such as poker, baccarat, and roulette), and sports betting. Some casinos also offer entertainment shows and restaurants. In order to gamble in a casino, patrons must be of legal age and follow the rules of the establishment. Gambling has been a part of human culture for millennia, with early evidence found in 2300 BC China, dice from 500 AD Rome, and cards appearing around 1400 AD. Casinos have become an integral part of modern society and are widespread throughout the world.
Often, casinos are built near or combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. In the United States, there are many casino locations, with Las Vegas having the largest concentration of them. Other popular gambling destinations include Atlantic City and Chicago, with many casinos also located on American Indian reservations that are exempt from state antigambling laws.
The most famous casinos are glamorous and opulent, offering high-stakes gambling alongside fine dining, designer shopping, and top-billed entertainment shows. These mega-casinos cater to the whims of the elite, with their opulent suites and rooms, spas, Michelin-starred restaurants, and designer boutiques. They can even feature high-flying circus acts and big-name concerts. However, not all casinos are created equal; some are just much bigger than others. Here are 10 of the largest casinos in the world.
