A casino is a public room or building where the playing of gambling games (such as roulette, baccarat, blackjack, poker, and slot machines) is the primary activity. It is also an establishment that has a hotel and/or restaurant. Modern casinos are often divided into a physical security force and a specialized surveillance department that monitors the casino using closed circuit television systems, known as “eye in the sky” technology.

Most casino games have mathematically determined odds that ensure the house has a long-term advantage over players. However, some games have a skill element, and players who possess sufficient skills can eliminate the house edge or vigorish. Such players are referred to as advantage players. Most casinos earn money by charging a commission, or “rake”, on the wagers placed by advantage players. Casinos also offer complimentary items or comps to their players.
