A casino, also known as a gambling house or gaming hall, is an establishment for certain types of gambling. Some casinos are stand-alone, while others are built in or combined with hotels, resorts, restaurants, retail shops, and other tourist attractions. Casinos are legal in some jurisdictions, while others ban them or regulate them to some extent. The largest casino in the world is the Casino Estoril in Portugal, which has a capacity of over 63,000 people.
In the United States, there are over 1,000 casinos. The Las Vegas Valley has the highest concentration of them, with Atlantic City and Chicago close behind. Many casinos also offer entertainment other than gambling, such as concerts and shows.
One of the more notable casinos is in Niagara Falls, Canada, which has a spectacular view of the Horseshoe Falls. This property has 1,500 modern slot machines and 40 table games, plus an area for placing bets on various sports events. There are also several gourmet restaurants and bars at the casino. Moreover, the site has a high-end hotel with 155 rooms.
