How Does a Casino Make Money?

A casino is an establishment where people can play gambling games. Modern casinos often combine gaming with other entertainment options, such as restaurants, hotels and shopping centers. They may also feature performances by entertainers and/or sports teams.

A large part of a casino’s profits come from the gambling games themselves. Slot machines, blackjack, baccarat and other table games provide the billions in revenue that casino owners earn each year. The games that a casino offers usually have a built in advantage for the house, which is calculated mathematically and called the “house edge” or the “expected value.” The casino makes money by taking a small percentage of each bet made by players, which is known as the vig (or rake).

Other ways that a casino makes money includes giving out free goods and services to its most loyal customers. These are known as comps and can include anything from free hotel rooms and meals to limo service and airline tickets. Casinos rate their customers based on the amount of time and money they spend playing, and those who qualify for the highest comps are often considered “good” players.

Gambling is not without its problems, however. Economic studies indicate that casinos actually hurt local economies by diverting spending away from other forms of entertainment and into the casino’s coffers. Plus, the costs of treating problem gamblers eat into any potential profits. Despite the bleak picture, casinos continue to thrive. They can be found around the world and are even legal on some American Indian reservations, which are exempt from state antigambling laws.
