What Is a Casino?

A casino is a gambling establishment that houses various games of chance. The games may include slot machines, poker, keno, craps, roulette, blackjack and more. The casino provides the money for the games, and it profits from the bets placed by patrons. It is a popular tourist attraction, and some cities are known for their casinos.

Because of the large amounts of currency that are handled, security is a major concern. Many different security measures are used, including cameras and armed guards. Some casinos also have high-tech surveillance systems that use a “eye in the sky” concept, which gives security personnel the ability to see any table or window at any time.

It is almost impossible for a patron to win more than a casino can afford to pay, so the house has a built in mathematical advantage. This advantage, often called the house edge, ensures that a casino will not lose money on any game, even if every player makes bets at a minimum amount. The edge is usually lower than two percent, but it adds up over the billions of bets that are made each year.

To offset this inherent advantage, casinos offer extravagant inducements to big bettors. These can include free spectacular entertainment, transportation and luxury living quarters. They also provide complimentary drinks and cigarettes while gambling, and offer reduced-fare transportation and hotel rooms to lesser bettors. Critics of casinos argue that compulsive gambling takes money from other forms of local entertainment and that the cost of treating problem gamblers cancels out any economic gains a casino might make.
