A casino is a place where people gamble on games of chance. While a casino has a lot more to offer than that, including theaters, restaurants and shops, its primary attraction remains gambling. Casinos make their money because of a built in statistical advantage that the casino has over its patrons, even though this edge is usually less than two percent. This advantage, combined with the millions of bets placed in the casinos each year, provides the billions of dollars that casinos earn in profits each year.

Most casinos offer a variety of gambling activities, from classic table games like blackjack and roulette to more modern video poker machines and electronic craps. Some casinos also offer live entertainment, such as a dazzling Vegas show or an intimate performance by a popular musician. The most famous casinos often have thousands of slot machines, while the biggest ones may feature hundreds of tables, including discreet private rooms for high rollers and VIP guests.

Casinos are located in most states that allow them, and many countries around the world have legalized them. Some casinos are operated by American Indian tribes, which are exempt from state antigambling laws. Others are owned by private businessmen and investment banks that make money by lending their money to the casinos.

Gambling is addictive, and casinos can be very dangerous places for those with a gambling problem. To help prevent addiction, it is best to decide before entering a casino how much you can afford to lose, and to stop playing once that amount has been lost.
