A casino (also called a gambling house or a gaming establishment) is an establishment where people can gamble. Guests may gamble by playing games of chance or skill, and some casinos also serve food and drink. Some casinos are integrated into hotels, resorts or cruise ships. Others stand alone as standalone facilities.

In the United States, the majority of casinos are located in Las Vegas and Atlantic City, New Jersey. Most states allow casino gambling, but the legality of casinos varies by state. Some states ban or restrict them, while others endorse them and regulate them. Regardless of their legality, casinos make millions of dollars annually in the United States and worldwide.

Most patrons don’t consider the casino’s design or decor when they place bets, but every detail is designed to keep them spending more and coming back—even though they’re always losing money in the long run. Learn how casinos use psychology to manipulate people into gambling their money away.

In addition to influencing the behavior of people who visit casinos, the gambling industry can have negative effects on the communities in which it operates. For example, a casino can cause local unemployment by employing lower-skilled workers who wouldn’t otherwise work in the area. This decrease in unemployment can boost the economy, but it often comes at a price—especially when it results in gentrification and higher rents for nearby homes. In addition, the large amounts of currency handled within a casino can present opportunities for both patrons and employees to cheat and steal.
