What Is a Casino?


A casino, also known as a gambling establishment, is a place where a variety of games of chance can be played for money. It is generally a very lavish place, complete with restaurants, free drinks, stage shows and dramatic scenery. There are many types of gambling establishments, but casinos are the most common. They are typically located in cities with large populations that want to gamble.

A casino generates profit by taking a percentage of all bets placed on its games. This is often called the house edge and can vary from game to game. In poker, for example, the casino takes a small fee, or rake, on each hand. It is not uncommon for a casino to offer extravagant inducements to big bettors in the form of free spectacular entertainment, hotel rooms and transportation.

Many of the games that are offered at a casino involve some element of skill, but most have a built in advantage for the house. For example, a roulette wheel has an expected return of only 1.4 percent. Craps has a lower expected return, but is more complex and requires significant knowledge of the rules. The advantage of the casino can be offset by the use of betting strategies, but even so, there is no guarantee that a player will win.

Due to the large amounts of money that are handled within a casino, both patrons and staff may be tempted to cheat and steal, either in collusion or independently. As a result, most casinos employ a number of security measures to deter these activities. These range from basic measures such as video cameras to sophisticated systems such as “chip tracking,” which uses microcircuitry in the betting chips to allow a computer to monitor the amount of money wagered minute by minute, and electronic monitoring of roulette wheels to discover any statistical deviation from their expected returns.
