A casino is a place to gamble, especially in games of chance. Casinos are governed by strict rules of conduct and behavior and are patrolled by security personnel. Some casinos offer a wide variety of entertainment and dining options, while others are more focused on the gambling experience.

Casinos use cameras and other technology to monitor the games. Many casinos have “chip tracking” systems that allow them to see exactly how much money is being wagered on each game minute-by-minute and quickly discover any statistical deviation from expected results. Roulette wheels are electronically monitored for anomalies, and a large percentage of table games now have built-in microcircuitry that allows the chips to be tracked.

Most casino games have a built-in advantage for the house that can range from a small amount to over two percent. This profit, known as the vig or rake, covers the cost of running the casino and gives it enough revenue to pay for things like fountains, giant pyramids and towers.

Casinos are also popular for their luxury, high-end services and amenities. The Bellagio, for example, has become famous for its dancing fountains and luxurious accommodations. It has even been featured in movies like Ocean’s 11, introducing the world to its brand of glamour. Other well-known casinos include the MGM Grand in Las Vegas and the City of Dreams in Macau. Some of the largest casinos are enormous resorts that feature restaurants, rooms, poker and other games, along with high-end shopping and nightlife.
