A casino is a gambling establishment that offers games of chance to customers. The games can be played both on tables and machines. Casinos may be massive resorts, like the Bellagio in Las Vegas or small card rooms in bars and restaurants. Casino-type games are also available in racetracks as racinos and at truck stops and other small businesses. Casinos bring in billions of dollars each year for the companies, investors, and Native American tribes that run them.

Many casino employees have security jobs, and casinos have strict rules to prevent cheating and theft, both by patrons and employees. Cameras throughout the facility help monitor and deter problems. Security personnel watch for blatant cheating, such as palming cards or marking dice, and note betting patterns that might indicate collusion. Computers help keep track of the amount of money wagered minute by minute and warn staff immediately of statistical deviations.

The Bellagio in Las Vegas is perhaps the best-known casino, and has appeared in countless movies and TV shows. However, it is far from the only casino, and there are plenty of other great places to gamble in Sin City and elsewhere around the world. Other famous casinos include the Casino de Monte Carlo, the Casino Lisboa and the Casino Baden-Baden.
