A casino is a place where people play games of chance for money or other prizes. It has become a popular tourist attraction, particularly in places where gambling is legal. Casinos offer a variety of games, and some have themed restaurants, stage shows and other entertainment. They may also feature shopping centers, hotels and other amenities. Some casinos are owned by government agencies or Native American tribes, while others are operated by private companies.

In the past, casinos drew high-profile patrons such as film stars, politicians and royalty. However, the business has always had a seamy side. As casinos became more regulated in the United States, mob figures stepped in to help them, providing funds and even taking sole or partial ownership of casinos. They also influenced the outcome of some games, using bribery and threats of violence against casino personnel.

Casinos rely on gambling to generate most of their revenue, and they make a substantial profit from the machines alone. They entice people to gamble by offering perks such as free drinks and elaborate stage shows. They also try to keep customers as long as possible to maximize revenue.

Casinos often have security measures in place to deter cheating and stealing. Due to the large amounts of cash involved, it is easy for players and dealers to collude or independently manipulate the games. Hence, casinos spend a lot of time and money on security. For instance, roulette wheels are electronically monitored to discover any statistical deviation from their expected results.
