A casino (plural casinos) is a building or room used for gambling. Casinos are most often built near or combined with hotels, restaurants, retail shops, and other tourist attractions. Many states have legalized casino gambling in some form, while others have prohibited it or regulated it. Some casinos are famous for their size or architecture, while others are known for the variety of games they offer.

The casino at Monte Carlo, located in the principality of Monaco, is considered by some to be the world’s premier gambling facility. The casino’s reputation for luxury and sophistication also has led to it being featured in several films, most notably the Ocean’s 11 heist movie. The Bellagio in Las Vegas is another renowned casino and tourist attraction, distinguished by its spectacular dancing fountains and luxurious accommodations.

Modern casino security is a combination of a physical force and a specialized department that operates the casino’s closed circuit television system. The physical force patrols the casino and responds to calls for assistance or reports of alleged or suspected criminal activity. The specialized surveillance department uses the camera systems to monitor activity throughout the casino, detecting suspicious or blatantly criminal behavior and helping to ensure the safety of patrons as well as the integrity of the casino’s assets.

Most casino patrons are required to wear wristbands or other identification at all times while on the premises. These bands are swiped electronically before each game session and allow the casino to track players’ activities and spending patterns. The information gathered by the casino computers is used for marketing purposes and to comp patrons. Typical comps include free or discounted food, drinks, and shows. In some casinos, players earn points that can be exchanged for cash or slot play.
