CASINO (from the Italian cassino, meaning “small house”) is a building or room in which gambling is carried out. The term is also used for the games of chance played there. Casinos often offer complimentary items to players, known as comps, and the amount of money gamblers win or lose is recorded by a croupier or other gaming official. Casinos may also feature live entertainment, top-rated hotels and restaurants, shopping centers and other forms of recreation.

The precise origins of gambling are unknown, but it is believed that some form of it has been enjoyed throughout history in almost every culture around the world. Today’s casinos are designed to stimulate the senses and appeal to a wide variety of tastes. They offer a wide variety of gambling opportunities, from traditional table games like blackjack and roulette to more modern slot machines and video poker. Many casinos have elaborate themes and decorations, and some are even named after famous people or places.

While musical shows, lighted fountains and hotel accommodations can lure visitors to a casino, the primary source of income is from gambling. The games of chance, including poker, blackjack, craps, keno and slot machines, provide the billions of dollars in profits that casinos earn each year. Despite this, casinos can be dangerous places. Patrons and staff are sometimes tempted to cheat or steal, either in collusion or independently; most casinos have security measures to deter this behavior. Casinos are also popular with organized crime groups, and the mob has been known to run several in the past.
