A casino is an establishment for gambling. These casinos offer games of chance and can be found in massive resorts, Las Vegas-style gaming houses, riverboats and barges, racetracks, truck stops, and other small businesses. Successful casinos bring in billions of dollars each year for the corporations, investors, and Native American tribes that own them. They also stimulate local economies by creating jobs and attracting tourism.

Many casinos feature live entertainment in addition to gambling. These events can include musical performances and stand-up comedy, but some casinos specialize in specific forms of entertainment. The Bellagio in Las Vegas, for example, is known for its spectacular fountain shows. Other famous casinos include the Casino de Monte-Carlo in Monaco, the Casino Lisboa in Lisbon, and the Casino de Baden-Baden in Germany.

Casinos are also known for offering comps, or complimentary items, to frequent gamblers. These may include free meals, hotel stays, or tickets to shows. During the 1970s, casinos in Las Vegas were famous for their cheap rooms and discounted travel packages, designed to maximize revenue from gambling.

Due to the large amounts of money handled by casino patrons, there is a high risk of theft. To protect their assets, casinos use security cameras and other technological measures. In addition, casino staff members are trained to spot suspicious activity. Despite these measures, there is always the possibility that casino patrons will try to cheat or steal, either in collusion with staff or independently.
