What is a Casino?


A casino is a place where people can gamble on games of chance, or skill. There are some games that are pure luck, such as slot machines, and others that require a bit of strategy or skill, such as blackjack, poker and roulette. Casinos can be large, extravagant places with many games and restaurants, or smaller rooms that only offer a few types of gambling. Casinos make billions of dollars each year for the companies, investors and Native American tribes that own them, as well as for state and local governments that collect taxes on gambling revenues.

Gambling probably predates recorded history, with primitive protodice and carved six-sided dice found in the earliest archaeological sites. The modern casino began to develop in the 16th century during a gambling craze that swept Europe. Italian aristocrats created private gaming rooms, called ridotti, where they could gamble on games such as dice, horse racing and baccarat with their friends and family.

Most casino games have a built-in house edge that ensures the casino a profit over the long run, even if only a small percentage of patrons win each day. This is sometimes referred to as the house advantage or expected value, and it makes it very rare for a casino to lose money on any game. Because of this, casinos often reward their best players with free items or services such as hotel rooms, dinners, show tickets and limo service. Ask a casino employee or information desk how to get your play rated for comps.
