A casino is a type of gambling establishment which offers various forms of gambling, such as slot machines and table games like poker and blackjack. Some casinos also offer entertainment shows. Casinos are typically located in tourist destinations or near hotels. They may also be found on cruise ships or in other places where gambling is legal.

In the United States, there are over 1,000 casinos. The largest casino is in Las Vegas, followed by Atlantic City and Chicago. The majority of American casinos are in commercial or tribal land-based locations, though there are some online-only operations as well. Casinos are regulated by both state and federal law, and most have security departments that monitor and deter criminal activity. Modern casinos are usually divided into three categories: gaming machines, table games, and random number games. Gaming machines are operated by computer programs that randomly select numbers. Table games involve one or more players who compete against the house, and are led by croupiers. Random number games are based on the selection of random numbers or other sources.

In addition to the usual range of gambling facilities, MGM Grand on the famed Vegas Strip is well known for its sports betting area. Here, visitors can flick a coin on American football, boxing and martial arts, as well as soccer, while they enjoy drinks and snacks from the bar. It is easy to see why this casino has become a renowned landmark.
