What is a Casino?



Casino (also known as a gambling establishment or club) is a place where people can play games of chance or skill for money. Modern casinos are large, lavishly decorated buildings with a variety of games and entertainment options. Some also have hotel rooms, restaurants, and spas. Some of the most famous casinos in the world are located in Las Vegas, and others can be found in cities around the globe.

Because of the large amounts of money involved, both patrons and staff may be tempted to cheat or steal, either in collusion or independently. Therefore, casinos spend a lot of time and money on security. For example, elaborate surveillance systems give the casino a high-tech “eye-in-the-sky” that can monitor all areas of the facility simultaneously. Cameras in the ceiling can be adjusted to focus on suspicious patrons, and are monitored by security workers in a separate room filled with banks of security monitors.

The casino business makes its money by charging a percentage of the total amount of bets placed by patrons. This percentage is known as the house edge, and it can vary from game to game. In a card game such as poker, where players compete against the dealer, the house’s advantage is less than two percent; in other games such as roulette and craps, it is much higher. In addition, some casinos make money by giving out complimentary items to gamblers, called comps. These perks are intended to encourage gambling and increase revenue.
