A casino is a gambling establishment that offers a variety of games of chance. These may include slots, table games like blackjack and roulette, and card games such as poker. Some casinos also offer live dealer gaming, where players interact with a real person via video stream to create a more authentic experience. In addition to offering a wide variety of games, casinos typically provide food and drinks for their customers.

Most states prohibit casinos, but a few, such as Nevada, have legalized them. Others have regulated them, while others, such as New Jersey and Illinois, limit their operations to Indian reservations. The majority of casinos are located in Las Vegas and Atlantic City, although there are some in Chicago and on American Indian reservations, which avoid state anti-gambling laws.

Casinos attract a diverse crowd, from casual gamblers to serious high rollers. They usually offer a selection of table and card games, along with electronic versions of popular sports. Players can also place wagers on horse races, keno, and other events. In the United States, many casinos are operated by commercial enterprises, including hotel chains and restaurants. Others are owned by individual patrons or organized crime figures.

Some casino patrons become addicted to gambling, which can lead to serious financial problems and other social issues. Studies show that compulsive gambling drains the economy, as it diverts resources from more productive uses. The casino industry tries to counteract this impact by providing treatment services for gambling addiction, and by promoting responsible gambling.
