A casino is a facility where people can play games of chance and, in some cases, skill. The casino industry includes a wide range of businesses, from massive resorts and hotels to smaller card rooms and even video game arcades. Casinos also offer food and beverages to their patrons. The games of chance that are played in casinos are governed by strict rules and regulations. In many cases, the house has a mathematical advantage over the players, which can be described as the house edge.

Gambling almost certainly predates recorded history, with primitive proto-dice known as astragali and carved six-sided dice found at archeological sites. However, the casino as a place where people could find a variety of ways to gamble under one roof did not develop until the 16th century during a gambling craze in Europe. It was then that Italian aristocrats established ridotti, which were private clubs where gambling was the primary entertainment.

Successful casinos make billions of dollars each year for the owners, corporations, investors, and Native American tribes that operate them, as well as state and local governments that collect taxes and fees. The casino industry employs tens of thousands of people and attracts millions of visitors each year.

In 2005, Harrah’s Entertainment reported that the typical casino patron was a forty-six-year-old female from an upper-income household. In general, these patrons tend to be more interested in poker and blackjack than other table games like craps or roulette. They are also more likely to prefer slot machines over other electronic gaming devices. Casinos also reward their biggest spenders with comps such as free hotel rooms, meals, drinks, shows, and limo service.
