A casino is an establishment for gambling and often includes a variety of games of chance such as slot machines, roulette, blackjack, poker and craps. Besides gambling, some casinos are known for their top-notch hotels, spas and restaurants and even live entertainment. Some are famous for their architecture, such as the Bellagio fountains in Las Vegas or the Casino de Monte Carlo in Monaco.

While the glitz, glamour and entertainment that is synonymous with the word casino helps draw in the crowds and generate revenue, the vast majority of the profits are made through games of chance, especially those with the highest house edge like blackjack, baccarat and craps. However, other sources of revenue at casinos include food and beverage sales, retail shopping, limo services and airline tickets.

Casinos are generally located in cities with a high income and tourism base and have become one of the most popular tourist destinations in the world. The industry has also grown to incorporate gaming facilities in other types of venues such as cruise ships and hotel resorts.

Casinos are regulated by the same laws as any other business and must adhere to strict codes of conduct and ethical behavior. They must be licensed and supervised by the government to ensure fair play. In addition, they must provide comps for their loyal customers which can include free hotel rooms, meals, show tickets and limo service. In the United States, casinos are primarily located in Nevada and Atlantic City, although some American Indian reservations have opened their own.
