A casino is a gambling establishment that offers different games. It is often a place where people can relax and enjoy themselves. Some of these casinos also provide restaurants, hotels and shopping malls.

The word casino was first used in Italian, meaning “little house” and is now used worldwide for a gambling hall. The most popular games in a casino are blackjack and roulette.

Unlike charity-run casinos, which are run by a nonprofit organization that is not geared to make money, a casino is a business and operates with a mathematical model that guarantees it will win in the long run. This ensures that the casino has a positive margin, or “house edge,” which is the average gross profit it expects to make from each game.
