What is a Casino?

A casino is a room or building where gambling games (such as blackjack, roulette, poker, and slot machines) are played. A casino may also offer food and drinks. The term can refer to a specific place or to an entire organization that operates a series of such rooms.

A modern casino is a complex enterprise. It employs many people, both full and part time. It is a major source of revenue for its owners, and provides entertainment for many visitors. It is a popular destination for tourists and business travelers, and is often featured in media coverage of Las Vegas or other gambling destinations.

In addition to traditional table games such as blackjack and poker, most casinos offer a variety of electronic gaming machines, including video lottery terminals (VLTs) and racetrack-style horse racing games. Some casinos specialize in a particular type of game, such as sic bo, fan-tan, or pai gow poker. A few casinos even have a dedicated area for table games like mah-jong and baccarat, and some have catwalks on the ceiling that allow surveillance personnel to look directly down through one-way glass on players at the tables and slots.

Gambling in some form is practiced in most societies throughout history. The precise origin of gambling is unknown, but it is commonly believed to have originated in ancient Mesopotamia, Egypt, Greece, or China. Most modern countries regulate casinos, and many have a state-owned lottery. There are also privately operated casinos.
