A casino is an establishment for certain types of gambling. It may also be known as a gaming house, a gambling hall, or a gaming room. A casino can also be a place where people socialize and entertain themselves. Some casinos are combined with hotels, restaurants, retail shops, and tourist attractions.
The term casino is most often used in the United States. Nevada is especially well known for its casinos, and Chicago and Atlantic City are also significant centers of casino gaming. However, it is possible to find casinos in many other states.
Gambling probably existed as early as recorded history, with primitive protodice and carved six-sided dice found in some archaeological sites. The modern casino is an industry that is regulated by law and offers a variety of games. Casinos earn money by charging a commission, or vig, on bets. The vig is usually higher on games that require some skill, such as blackjack, than on those that are purely chance, such as roulette and poker.
Casinos attempt to persuade gamblers to play by creating an atmosphere of excitement and noise. They use bright and sometimes gaudy floor and wall coverings that are designed to stimulate and cheer the players. They offer drinks and snacks, and encourage players by shouting encouragement. Some casinos also offer comps to big spenders, such as free hotel rooms or meals. The amount of money a player gambles during a trip to a casino is called his or her bankroll.
