What is a Casino?


A Casino is a gambling establishment that allows customers to gamble and win money. The casino may add a variety of amenities to help attract customers and enhance the gambling experience, such as restaurants, free drinks, stage shows, etc. Casinos are most commonly found in hotels, resorts, or entertainment centers. They have a variety of games to choose from, including blackjack, craps, roulette, baccarat and video poker. Each game has a built-in house advantage that, over time, will make the casino more money than it loses. This house edge is known as the vig or the rake.

Despite the flashing lights, glamorous crowds and elaborate themes, casinos would not exist without the games of chance that draw people in to gamble. Slot machines, keno, baccarat, poker, blackjack and other popular games account for the billions in profits raked in by casinos every year.

While a large percentage of the profits are generated by games of chance, casinos rely on security to protect their assets and patrons. Security personnel are constantly on the lookout for any suspicious betting patterns or behavior. Most casinos use sophisticated technology to supervise the games. For example, some tables have “chip tracking” systems that allow surveillance to keep tabs on the amount of money wagered minute-by-minute and to alert staff quickly if there is a statistical deviation from expected results. Other casinos have catwalks above the gaming floor that allow security to watch players directly through one-way glass.
