A casino is a place that allows people to gamble. It usually has games like poker, blackjack, roulette, and craps. It also has non-gambling activities like restaurants and hotels. The casino industry generates billions of dollars for its owners every year. It is often a tourist attraction. Many casinos use musical shows, lighted fountains, shopping centers and lavish hotels to draw in tourists. However, the vast majority of revenue comes from gambling.

Casinos typically have a high mathematical expectancy of profit and it is rare for them to lose money for even one day. This virtual guarantee of gross profit makes them attractive investment targets. They also offer big bettors extravagant inducements such as free spectacular entertainment, luxury hotel rooms and transportation, and reduced-fare casino accommodations.

Security is a key aspect of casino operation. Cameras are used to monitor patrons and employees to detect cheating. The dealers are heavily supervised and can quickly spot blatant attempts to manipulate the game such as palming, marking or switching cards or dice. The pit boss and table managers have a broader view of the tables and can identify betting patterns that may signal cheating.
