What Is a Casino?

A casino is a gambling establishment, often in the form of a large building, that offers a variety of games to its patrons. These games include traditional casino fare, like blackjack, poker and roulette, as well as other popular casino games, such as video slots, which offer a wide range of themes and bonus features. Most casinos also offer sports betting and other forms of interactive gaming.

The precise origin of gambling is unknown, but it is likely that it predates recorded history, with primitive protodice — cut knuckle bones or carved six-sided dice – found in the oldest archaeological sites [Source: Schwartz]. In the 16th century, as the gaming craze swept Europe, Italian aristocrats hosted private parties at their homes, called ridotti, where they could gamble on horse races and other events.

Today, casinos have evolved into highly profitable businesses that feature luxurious accommodations and high-end entertainment options, such as gourmet restaurants, dance clubs and awe-inspiring displays of art. They make money by establishing a built-in advantage for themselves in each game, known as the house edge. This may be only a few percent, but over millions of wagers, it can add up to significant profits.

A casino’s profitability is further assured by offering “comps” to big bettors, free goods or services that are based on the amount of money they spend at the casino. These can include anything from free hotel rooms to dinners and show tickets to reduced-fare transportation and even airline and limo service.
