What is a Casino?

A casino is an establishment where people can gamble and play games of chance. There are many different types of casino games, from the classic table games like blackjack and roulette to newer machines such as video poker and slots. Casinos are also known for their world class entertainment and stage shows.

The term casino is most often associated with gambling in Las Vegas and Atlantic City, but there are casinos located in a variety of other places as well. These include locations on American Indian reservations, which are not subject to state antigambling laws, and in countries where gambling is legalized, such as Macau, where the casino industry has boomed since the 1980s. Many states have legalized casino gambling in some form as well.

Casinos make money by taking a percentage of every bet made, a practice known as vigorish or the rake. In addition, the math behind most casino games gives the house a built in advantage, which can be small (less than two percent) but adds up over time. This is why casinos offer comps to high bettors, offering them free hotel rooms, meals, show tickets and even limo service and airline tickets.

Because large amounts of money are handled within a casino, both patrons and staff may be tempted to cheat or steal. This is why casinos spend a great deal of time and effort on security. In addition to obvious surveillance cameras, there are a number of other security measures. For example, the routines of casino games create predictable patterns that are easy for security personnel to spot when something is out of the ordinary.
