What is a Casino?


A casino is a building or room where people can gamble and play games of chance. Modern casinos typically contain a variety of gambling games such as blackjack, roulette and video poker. Some, such as baccarat, are more popular than others. Casinos are a major source of income for many cities and countries, and are sometimes known as gaming establishments or gambling houses.

The idea of a casino is thought to have originated in the 16th century, when a gambling craze swept Europe and Italian aristocrats gathered in private parties called ridotti to gamble. Although technically illegal, these parties were not usually bothered by the Inquisition, and so grew into casinos as they are known today.

Modern casinos are financed by a combination of public and private money. The public money is provided by taxes on gambling winnings, and the private money comes from investors who see a good return on investment. These investments are often accompanied by lavish amenities such as fountains, giant pyramids, towers and replicas of famous landmarks. The casino advantage – the built in mathematical expectation that the casino will win a bet – can be as low as two percent, but over millions of bets it adds up to a substantial amount of revenue for the casino.

Some critics argue that casinos taint the reputation of legitimate businessmen and deprive local communities of tax revenue. Additionally, they are said to decrease property values and create a culture of addiction that eats into the profits of local businesses and drains the economy.
