A casino is a public place where people can play games of chance for money. Casinos often offer free drinks, stage shows, restaurants and other amenities. They can be found in large resorts and hotels, standalone buildings, and on boats and barges. Casino-type game machines are also often located at racetracks, truck stops and other businesses. Successful casinos bring in billions of dollars each year for the companies, investors and Native American tribes that own them. They also provide jobs and tax revenue for local governments.

A large percentage of casino patrons are women, and the average age is forty-six. Many are parents with above-average incomes, and they frequently take weekend or vacation trips to gamble. The gambling industry is a major contributor to tourism in some areas.

Casinos rely on customer service to keep their clientele happy. They provide perks to “good” players, including free hotel rooms and meals. They may even give out airline tickets and limo service to high-volume players. This is called comping, and it is a way for the casino to reward its biggest spenders.

Casinos make their money by offering a built-in statistical advantage, known as the vig or rake. The advantage can be very small – as little as two percent – but it adds up over millions of bets and makes casinos profitable enough to build elaborate hotels, fountains, giant pyramids and towers, and replicas of world landmarks. Casinos also have elaborate surveillance systems that allow security workers to watch every table, window and doorway at the same time.
