A casino, or gaming hall, is a facility where people play games of chance for money. Casinos are usually located in resorts or tourist destinations and offer a variety of casino games, such as blackjack, roulette, poker, and slots. Some casinos also feature restaurants and bars. Casinos are usually heavily guarded and have security cameras. Some even have a full-time police force.

The precise origin of gambling is unknown, but it is believed to predate recorded history. Primitive proto-dice, such as carved six-sided ones, have been found in archeological sites dating to the 3rd millennium BC [Source: Schwartz]. The modern casino developed in the 16th century during a gambling craze that swept Europe, with wealthy Italian nobles often hosting parties known as ridotti where they could enjoy their favorite games.

Today, casino gaming is a massive industry. In the United States alone, there are over 1,000 casinos, with more opening each year. Many states have legalized casino gambling, attracting tourists and increasing property values in local areas.

The number of games available in a casino can vary greatly, but the majority are table games like baccarat, chemin de fer, and blackjack. Craps and roulette are common as well. Casinos may also feature card games such as poker and trente et quarante. The majority of casino games have a built in advantage for the house, with odds that are uniformly negative from the player’s perspective. This house edge is generated through a combination of commissions and rake, the latter a percentage of money bet by players on each hand or spin of the wheel.
