A casino, or gambling house, is a place where people can play a variety of games of chance for money. It can also be an entertainment center where live music, dancers and other performers perform. Casinos are most often built near or combined with hotels, restaurants and other tourist attractions. Many countries have laws regulating the operation of casinos.

The term casino can be applied to places that offer a wide range of gambling activities, but the majority of these facilities are defined by their concentration of table games. These include baccarat, chemin de fer (French for “iron wheel”), blackjack, and keno. Casinos also have a few card games, such as poker and pai gow, and some offer regular tournaments.

While gamblers may have an element of skill in some games, such as baccarat and blackjack, the overall odds are against them. These odds, calculated by mathematical formulae, are known as the house edge and variance. Casinos can maximize their profits by minimizing the house edge and variance, as well as by providing complimentary items or comps to patrons.

Casinos are a major source of employment in some cities, and they can boost the local economy by drawing visitors from outside the area. However, they can also have negative economic effects. For example, studies show that compulsive gamblers generate a disproportionate share of the profits in casinos; and the costs associated with treating problem gambling can reverse any economic benefits that the casinos may bring to a city or region.
