A casino is a building or large room in which gambling games are played. Various kinds of casino games are played, including slot machines, table games, and electronic gambling. In addition, casinos are also known for hosting live entertainment events and exhibits. In some countries, casino gambling is legalized under the jurisdiction of local government bodies.

In some cases, casinos are operated by private companies. In other cases, they are owned by state governments, local municipalities, or Native American tribes. Many states have laws that regulate the licensing and operation of casinos. In the United States, the majority of casino operations are regulated by the state.

Gambling has been a part of human culture for millennia, with evidence of dice from 2300 BC and playing cards by the 1400s. Modern casino gambling began in Atlantic City, New Jersey, in 1978 and spread to other places in the 1980s, including on American Indian reservations. During this period, many states passed laws to allow casino gambling.
