What Is a Casino?
A casino is a building or room in which gambling games are played. The term is also used to describe the business of running such a place. The largest casinos in the world are located in Las Vegas and Macau, with China showing potential for growth. There are a wide variety of games played at a casino, and each has its own history and strategy. Some casinos even invent their own games to attract players. There are some common casino games, however, that almost all casinos offer.
Gambling probably predates recorded history, with primitive protodice and carved six-sided dice found in ancient archaeological sites. But the modern casino as a gathering place for multiple forms of gambling under one roof didn’t develop until the 16th century, during a gambling craze that swept Europe. In Italy, wealthy nobles met at private clubs called ridotti, where they gambled with their peers. Often, these venues were technically illegal, but their patrons were rarely bothered by authorities.
Today, casinos are much like indoor amusement parks for adults, with lavish hotels, shopping centers, restaurants and dazzling entertainment options to draw in the crowds. But they wouldn’t exist without the games of chance, which provide billions in profits every year.
Although casinos have many ways to earn money, they all rely on a built in advantage, or “vig,” which is the difference between a game’s true odds and the bettors’ expected returns. This vig can be as low as two percent, but it adds up over time and generates enough income for casinos to build elaborate hotels, fountains, pyramids and replicas of famous landmarks.
