A casino (or gambling house) is an establishment where people can play a variety of different games of chance for money or other prizes. Casinos are most often built near or combined with hotels, restaurants, retail shops, and other entertainment facilities. Many casinos also offer live entertainment such as concerts and stand-up comedy.

A player’s skill in a casino game can reduce the inherent long-term disadvantage of that game, and such players are known as advantage players. However, most casino games have a house edge that is not negotiable. The mathematical analysis of casino games is a branch of mathematics called gaming analysis, and the professionals who study this field are known as gaming mathematicians and analysts.

Gambling is a widespread activity throughout the world, and there are many types of casino games. The most common are card games and table games such as blackjack, roulette, and craps. In some jurisdictions, casinos are also permitted to operate slot machines. It is also possible for a casino to offer sports betting, which is often done on a large screen television. In the United States, casinos are regulated by state law and must be licensed to operate. Some states prohibit gambling or limit it to certain activities, such as horse racing or lotteries. In addition, some casinos are located on American Indian reservations and are not subject to state antigambling statutes. These casinos are often referred to as Native American casinos.
