A casino, also known as a gambling house, is an establishment for certain types of gambling. It features games of chance and is operated by a live dealer or croupier. In addition to slot machines, casino floors feature a variety of table games such as blackjack and roulette. Casinos often include other entertainment such as shows or tournaments.

Gambling likely predates recorded history, with primitive protodice and carved knuckle bones discovered at some of the oldest archaeological sites [Source: Schwartz]. But the modern casino as a place where patrons can find a variety of ways to gamble under one roof didn’t emerge until the 16th century, during a gambling craze in Europe. Then, European aristocrats held private parties in gaming houses called ridotti.

Modern casinos offer a wide range of entertainment and dining options for their guests, but the majority of their profits come from gambling. While lighted fountains, musical shows and elaborate themes help draw in the crowds, casinos would not exist without the billions of dollars they rake in each year from games of chance like blackjack, craps, baccarat, roulette and keno.

Something about casino gambling just seems to encourage people to cheat, steal and lie in order to win a jackpot. That’s why casino security is such a major part of the business. Casinos use a combination of physical security forces and specialized surveillance departments to patrol the property and keep an eye on suspicious or definite crime activity. They also enforce rules and regulations governing their patrons’ behavior.
