What Is a Casino?


A casino is a gambling establishment where patrons wager money on games of chance or skill. Some of the more popular games include roulette, blackjack, poker, baccarat, craps, and video poker. Casinos also offer complimentary items (complimentary goods or services) to gamblers, such as meals, drinks, hotel rooms, show tickets, and limo service. Casinos make their profits from the house edge, which is a built-in advantage for the house in each game. This advantage is mathematically determined and can be lower than two percent, depending on the game and its rules.

A casino can be large or small, and its atmosphere is typically designed around noise, light, and excitement. The ambiance is meant to distract patrons from the fact that they are gambling. Casinos are most famous for their games of chance, but some have more sophisticated games that require some skill.

Casinos have security measures to prevent cheating and theft by both customers and employees. These usually include cameras and other electronic devices. In addition, casino employees are trained to watch for suspicious behavior. For example, the way a dealer shuffles cards and places them in the betting circle follows certain patterns that are easy for security personnel to recognize. These security measures are a necessary part of the business, because, as with any gambling establishment, there is always the possibility that someone will try to steal or cheat.
