A Casino is an establishment where a variety of gambling activities take place. While a casino may feature restaurants, free drinks, stage shows and other luxuries to draw in customers, it is really about the gambling that makes casinos so profitable. Slot machines, blackjack, roulette, craps, baccarat and other games of chance provide the billions in profit that casinos rake in every year.

Casinos are mainly found in the United States, where there are more than 1,000 such establishments. The most famous is Las Vegas, followed by Atlantic City and Chicago. Many American Indian reservations also operate casinos, which are not subject to state anti-gambling laws.
