A Casino is a facility for gambling. Its clientele may range from seasoned gamblers to casual tourists. Many casinos are combined with hotels, restaurants, retail shops and other tourist attractions. Some are located in places that are well known for their gaming, such as Monte Carlo and Las Vegas. Some are famous for a specific type of game, such as the Casino de Paris or Dragonara Palace in Malta.

In modern casinos, patrons gamble by playing games of chance or skill (including poker, blackjack and video poker) against the house. Almost all casino games have a mathematical expectation of winning, giving the casino a profit over the long run. The house edge is usually a fraction of the total amount wagered, though in some games (e.g., blackjack) the house advantage is substantially higher.

Gambling is a popular leisure activity worldwide, and is regulated in many jurisdictions. The most important factor in determining the legality of a casino is its financial stability. Casinos must meet strict minimum standards of capitalization, liquidity and leverage, and must submit regular reports to regulatory authorities. In addition, casinos are subject to a variety of other laws, such as those concerning alcohol and smoking.

There are many types of casino games, and they are available in all parts of the world. The Bellagio, for example, offers a large variety of traditional and modern casino games, including blackjack, roulette, craps, three card poker, baccarat and video slot machines. The games are regulated by law and the rules are clearly marked.
