A casino (plural casinos) is a gambling establishment. Customers gamble by playing games of chance or skill, and win money or other prizes based on the results of those games. The games are designed with mathematical expectancies to ensure that the house always wins, or at least that it never loses more than it pays out. The advantage over the patrons is called the house edge. Casinos are legal in some jurisdictions and have become a major tourist attraction.
In addition to gambling, many casinos offer other entertainment activities such as stage shows and concerts, restaurants, bars, and shopping areas. Some also have golf courses or spas. Casinos can be found in a wide variety of locations, including major cities, tourist destinations, and Native American reservations.
Large amounts of money are handled within a casino, and both patrons and employees may be tempted to cheat or steal. For this reason, most casinos have security measures in place. These measures include cameras, secure betting areas, and rules of conduct that prohibit actions that could compromise security.
The world’s biggest casino is in Las Vegas, Nevada. It is operated by the Mashantucket Pequot Indian tribe and features 4.7 million square feet of gaming space. The facility has several high-end restaurants and is home to one of the world’s largest theatres. It has also been featured in a number of films, including James Bond movies and Eugene Levy’s Once Upon A Crime.
