A casino is a gambling establishment, also known as a gaming house or a tavern. Customers gamble by playing games of chance, or games with a small element of skill, such as blackjack, baccarat, and roulette. Most games have mathematically determined odds that ensure the house has an advantage over the players, which can be expressed more precisely as a negative expected value. This advantage is sometimes called the house edge, and it is the source of the casinos’ profitability. Casinos may also give out complimentary items or comps to gamblers.

Some of the most famous casinos in the world are located in exotic locales, such as the luxurious resort town of Baden-Baden in Germany, where European royalty and aristocracy once came to play. Others are modern and technologically sophisticated, such as the City of Dreams in Macau, China, which opened in 2004 and features more than 3,000 slot machines and tables.

In the United States, casinos are regulated by state law. Many are owned and operated by Indian tribes, while the remaining are privately owned and managed. Most casinos offer a variety of table and slot machine games. They also feature a wide selection of restaurants and bars, as well as live entertainment. Some casinos even offer sports betting, which is becoming increasingly popular.
