Explanation
A casino is a building where people can gamble and play games of chance. Your grandmother might enjoy taking weekend bus trips to the nearest casino with her friends. Many casinos are near — or inside — hotels, and include opportunities to dine, drink, and shop. The main event at a casino, however, is the chance to gamble either by betting money on games like blackjack or poker, or by putting coins in a slot machine. Casino is also the name of a card game. The word comes from the Italian casa, or "house." In the 1800s casino came to mean "building for aristocratic gambling."
