Casino, meaning a place where games of chance are played, is a business that generates billions in profits each year. While elaborate themes, musical shows, shopping centers, luxury hotels and a host of other amenities help draw in patrons, casinos would not exist without the games of chance themselves: Slot machines, blackjack, roulette, craps, poker and more are what make up the majority of the gambling revenue generated by U.S. casinos each year.

Many casino patrons gamble for the thrill of winning, which is why the industry often provides lavish inducements to big bettors. This can include free spectacular entertainment, private transportation, elegant living quarters, and even reduced-fare airfare for their entire family. In addition to the excitement of gambling, a number of studies have shown that playing games of chance can improve mental talents such as critical thinking, math skills and pattern recognition.

Besides attracting visitors, the casino business also boosts local economies. The millions of people that visit casinos annually spend money in local restaurants, hotels and other businesses. Casinos also boost local governments through taxes and economic development grants.
