A casino is a place where people gamble and play games of chance. Casinos often have a distinctly colorful atmosphere, and are designed around noise, light, and excitement. They also offer food and drinks to their patrons. Some casinos specialize in certain types of gambling, such as craps or poker. The term casino may also refer to a specific building or room within a larger gambling establishment.

Casinos make their money from the ârakeâ, the commission they take on each hand of a table game like blackjack or baccarat. Some casinos may add other sources of revenue such as musical shows or shopping centers but the bulk of their profits comes from gambling. Slot machines and video poker machines generate the most income for American casinos, attracting customers who play quickly at small sums with high volume. Craps and roulette, on the other hand, attract big bettors and require dealers to monitor and manipulate game outcomes to reduce the house edge to 1.4 percent or less.

Gambling almost certainly predates recorded history, with primitive protodice and carved knuckle bones discovered in archaeological digs. The modern casino probably originated in the 16th century, with a gambling craze in Europe and a desire by rich Italian aristocrats to avoid the inquisition.

Today a casino is more than just an enclosed room with games of chance; it is a complete entertainment complex. It offers food, beverage and live entertainment as well as gambling. In addition, it requires a large staff to run and maintain the facility. Because of the large amount of money handled in a casino, both patrons and employees may be tempted to cheat or steal, either in collusion or independently.
