A casino is a gambling establishment that offers a wide range of games of chance and, in some cases, skill. It also provides food, drinks and entertainment to patrons. Casinos are designed to stimulate the senses of sight, sound and touch to make gamblers want to play more and stay longer. They often offer a variety of complimentary items to gamblers known as comps. Throughout history, casinos have evolved into highly elaborate venues designed to entertain and entice gamblers.
Whether they are in the glamorous casino resorts of Las Vegas or the elegant spa town of Baden-Baden, most casinos feature stimulating sights, sounds and smells to keep people gambling for as long as possible. The lighting is bright and cheerful and the machines and table games are arranged in a mazelike fashion to encourage wandering patrons to see what else might interest them. The sounds of slot machine bells and whistles are electronically tuned to the musical key of C to be pleasing to the ear and fit in with the ambient noise of the casino.
While most casino games are purely based on luck, many have a built-in advantage for the house. This advantage, mathematically determined by the odds, is referred to as the house edge. The house edge exists even in games where players compete against each other, such as poker or blackjack. In such games, the house takes a percentage of each player’s bets called the rake.
Because casinos are businesses, they have to ensure their profitability, even if most of their customers lose money. To maximize their gross profits, they designate specific games as “high-roller” games and provide special inducements to those who place large bets. These perks can include free spectacular entertainment, expensive hotel rooms and luxury cars.
The casino industry is regulated to protect its customers from fraud and other illegal activities. Because of the large amounts of money that are handled within a casino, security is a high priority. Casinos use surveillance cameras to monitor patrons and their activities, and most have security guards posted throughout the premises.
The term casino originates from Italian and is related to the word casona, which means “cloister.” The early casino was a small clubhouse for members to socialize, drink and gamble in private. Eventually, other European countries adopted the concept, and the term came to mean a building dedicated to gambling. Today, the casino industry is worth billions of dollars. People of all ages visit casinos to place bets and win prizes. In the United States, the legal age to gamble is 21. People who are under this age are not permitted to gamble, though they may be allowed to loiter in the vicinity of a casino. The casino industry is growing in other parts of the world as well, particularly in Asia, where casinos have opened to serve local populations. Casinos often feature traditional Far Eastern games such as sic bo, fan-tan and pai gow.
