A casino is an establishment for certain types of gambling. Modern casinos are usually combined with hotels, resorts, restaurants, retail shops and other tourist attractions. Some casinos are also known for hosting live entertainment such as concerts and sports events. Casino may also refer to:

In some jurisdictions, casinos are licensed and regulated by the government. Some states control the number of gaming machines or tables they permit, while others limit or ban them entirely. In the United States, there are a number of legal ways to operate a casino, including on riverboats, Indian reservations, and in some states, in unlicensed, privately owned gambling halls called “private clubs”.

Because of the large amounts of money involved, both patrons and staff of a casino may be tempted to cheat or steal, either in collusion or independently. To counter this, most casinos have security measures in place, such as closed circuit television (CCTV) cameras that provide a constant eye-in-the-sky view of the casino floor, and a separate department that monitors and controls the casino’s CCTV systems.

Many casinos specialize in games that require skill, rather than just chance, such as blackjack, baccarat and poker. Some casinos offer a mixture of these games, as well as slot machines and other electronic games. Casinos in Asia often feature traditional Far Eastern games such as sic bo, fan-tan, and pai gow. Some of the world’s largest casinos are located in Las Vegas, which is famous for its large variety of games and opulent architectural style.
