A casino is an establishment that offers various forms of gambling, including slot machines and table games like poker and blackjack. Patrons must be of legal age to enter and can exchange money for chips or credits that can be used on the games. Many casinos also host entertainment shows and other events. Casinos operate under strict regulatory oversight and enforce rules that thwart fraud and safeguard players. They employ an intricate web of security measures, including cameras and trained staff.

Initially, casinos were not open to the general public but were reserved for high rollers and the aristocracy. They grew in popularity with the introduction of legalized gambling in Nevada, where they were able to draw gamblers from all over the country and even abroad. Other states took notice and began to license casinos as well.

The modern casino carries on the tradition of the old gaming houses by offering a variety of gambling activities, from baccarat and craps to roulette and blackjack. It also hosts a number of poker variations and is one of the few places where players compete against each other rather than the house. These games generate a small percentage of profit for the casino, which is earned either by taking a commission on each bet or by charging an hourly fee.

The Aria, for example, features a sleek, contemporary atmosphere that separates it from other Vegas resorts. It is home to a collection of art from world-renowned artists and also boasts a restaurant, a three-ring rotating stage for live performances, and a flexible auditorium. Its dazzling interior also showcases a mix of mid-century Italian American and Asian motifs.
