Casino is the name given to a gambling establishment where various types of gambling activities take place. The word is derived from the Italian word for small house or club and the name fits perfectly because casinos are indeed small houses of their own with different games, amenities, and services that provide gamblers with an exceptional experience. Casinos can also be found online where they are a major part of the online gaming industry.

While musical shows, lighted fountains and lavish hotels help to draw people into a casino, the vast majority of a casino’s profits come from games of chance. Slot machines, blackjack, roulette, craps, keno and other table and card games account for billions of dollars that US casinos rake in every year.

Gambling in some form has existed in virtually all societies throughout history. The precise origins are unknown, but it is believed that gambling was first established as a way to settle disputes among individuals and families, and later in commercial settings as a way of raising capital.

Because large amounts of money are handled within a casino, security is a primary concern for all casinos. Staff members are trained to spot blatant cheating and stealing, and sophisticated surveillance systems offer an “eye-in-the-sky” view of the casino floor. Each player at a table game has a pit boss or manager who tracks them, looking for betting patterns that indicate dishonesty. Some casinos even have their own detective agency to investigate alleged crimes and misdemeanors committed by patrons.
