A casino is a place where people can gamble and enjoy other activities. Casinos are sometimes built near hotels, restaurants, retail shopping, cruise ships and other tourist attractions. People can play a variety of games in casinos, such as blackjack, poker, roulette, craps and slot machines. Many casinos also offer live entertainment events, such as stand-up comedy and concerts.

The United States remains the undisputed frontrunner in casino gambling on a global basis, with profits from slots, black jack, roulette and craps providing billions of dollars in profit each year for casinos. These profits have led some critics to question whether casinos benefit local economies. They argue that casino gambling diverts resources away from other types of entertainment and that the costs of treating problem gamblers and lost productivity reverse any economic benefits from the gaming industry.

While some people may view the casino as a place of sin and temptation, others see it as a source of socialization, entertainment and even fun. Casinos often have bright and sometimes gaudy floor and wall coverings that are designed to create an energetic and cheery atmosphere. They also offer a variety of drinks, food and entertainment, such as floor shows. In addition, casinos try to reward their high-spending customers with comps, or complimentary goods and services. These perks include free hotel rooms, meals and show tickets. Casinos may even give out limo service and airline tickets to frequent visitors. Some casinos are renowned for their luxurious amenities and may feature world class spas and golf courses in addition to their gaming offerings.
