A casino is a gambling establishment where people can gamble and play games of chance. Its main business is the money it makes from gambling, but it also offers other services and entertainment to its customers such as restaurants, hotels, shows and shopping centers. The main gambling game in a casino is poker, craps and roulette. Other games include blackjack, video poker and slot machines. Casinos are often built around a central theme, and the whole atmosphere is designed around noise and light to make it as exciting as possible for players.


Every casino game has a built in advantage for the house, and even games with an element of skill (like poker) give the house a small edge. This edge can be very low, but it adds up over millions of bets to generate the billions of dollars in profits casinos rake in annually.

To help prevent cheating, many casino games have a number of rules and procedures that must be followed in order to ensure fairness. In addition, most casino employees are trained to spot any signs of cheating or impropriety. Casino security staff have an eye in the sky with high-tech cameras that watch every table, window and doorway, and can be shifted to focus on suspicious patrons by workers in a separate room filled with banks of security monitors.

Casinos attract a certain type of customer, mostly older adults from middle to upper class income families who are looking for a little excitement and a chance to win money. Depending on their level of spending, they are offered free show tickets, hotel rooms, meals and other perks known as comps.
