What is a Casino?

A casino (or kasino, from the Spanish for “gambling house”) is an establishment where people can gamble. Casinos usually offer a variety of gambling games and are often combined with hotels, restaurants, retail shops and other tourist attractions. Many casinos are also known for their entertainment offerings, such as live shows or concerts.

Gambling almost certainly predates recorded history, with primitive protodice and carved six-sided dice being found in archaeological sites, but the casino as a place for people to find a variety of ways to gamble under one roof did not develop until the 16th century during a gambling craze that swept Europe. Italian aristocrats held private parties at venues known as ridotti, which were technically illegal, but the patrons were so obsessed with gambling that they rarely bothered the authorities.

Modern casinos are heavily regulated and have many security measures in place, both to protect the patrons’ money and their privacy. Casinos employ a variety of surveillance cameras and other electronic security measures, and employees regularly check that tables are paying out correctly. In addition, many casinos use technology to monitor the games themselves; for example, in “chip tracking,” betting chips contain microcircuitry that interacts with electronic systems that record the amount wagered minute by minute, and roulette wheels are electronically monitored to discover any statistical deviations from their expected results.

Casinos make money by taking a small percentage of all bets placed, a practice known as the vig or rake. The advantage of the casino can be as low as two percent, but it adds up over the millions of bets that are placed in a single day. In addition to vig, casinos make money by selling slots, table games and other gambling devices. They may also offer free goods and services to certain frequent patrons, such as hotel rooms, meals and show tickets.
