A casino is a gambling establishment with slot machines, table games and other gaming equipment. The facility is governed by a regulator, which ensures the integrity of the games and protects the patrons’ money. A casino also offers complimentary items, or comps, to gamblers. The term casino may also refer to an online version of a gambling establishment.

In the United States, casinos are mostly private businesses that operate under license from state gaming boards. In some cases, they are owned by local tribes. The business is regulated by laws governing the licensing, security and operation of the casino. A casino may also offer a variety of entertainment and dining options.

The majority of a casino’s profits come from its gaming operations. Slots, blackjack, roulette, craps, baccarat and video poker are the most popular games at modern casinos. They are characterized by mathematically determined odds that give the house an edge over the players. In games where skill is involved, the advantage is slightly lower.

Besides offering a wide range of games, casinos also provide amenities such as hotel rooms, restaurants, shopping centers and nightclubs. They are usually equipped with a surveillance system and have security forces to prevent crime.

In the United States, casinos are usually licensed by state gaming boards and regulated by federal and state laws. Many casinos are located in cities with a large population of tourists, such as Las Vegas and Atlantic City. Others are on American Indian reservations and not subject to state antigambling laws.
