A Casino (also known as a gambling house or a gaming establishment) is an institution offering various forms of gambling. Most casinos offer table games such as blackjack and roulette, with the majority of their revenue coming from slot machines. In addition, most casinos feature poker rooms, where players compete against each other for winnings and the casino takes a small fee called the rake. Many casinos also have a wide variety of other games of chance, and some even host live entertainment such as concerts or comedy shows.

Casinos are regulated by law to ensure fair play and prevent criminal activities. They often employ a large number of security measures to protect both patrons and staff. These include armed guards, closed circuit television surveillance systems, and catwalks over the gaming floor that allow security personnel to look down directly on the games, through one-way glass.

Casinos attract visitors from around the world who come to gamble, enjoy the ambiance, and experience the excitement of the games. Many casinos also feature upscale restaurants, bars, and other entertainment options to create a complete experience. In addition, some casinos are part of larger resorts that provide additional amenities such as swimming pools, luxury spas, shopping boutiques, and hotels.
