What Is a Casino?


A casino is a building or room in which people play games of chance for money or other rewards. Modern casinos offer a variety of gaming options, including slot machines, blackjack, roulette, craps, and baccarat. Some casinos are built as massive resorts; others are located on boats or barges that travel on waterways; and still others are found in racetracks and at some bars, restaurants, truck stops, and other small businesses.

Successful casinos bring in billions of dollars each year for the companies, investors, and Native American tribes that own and operate them. They also generate significant revenue for the cities, states and countries in which they are located.

Casinos make their money by charging a fee to patrons who place bets, called a vig or rake. This fee can be as low as two percent of a bet’s total value, but it adds up over the millions of gamblers who visit each year. In addition, casinos often earn money from the sale of food and drink, and from the rental or lease of hotel rooms.

Since casinos handle large amounts of money, they are vulnerable to theft and cheating by both patrons and employees. To combat these problems, casinos use sophisticated security systems. For example, high-tech chips in table game betting chips have microcircuitry that allows them to be tracked minute by minute; and roulette wheels are electronically monitored to discover any deviations from their expected results. In addition, many casinos have cameras positioned throughout their facilities.
