A casino is a public place where various games of chance and gambling take place. It offers a variety of luxuries to help draw patrons, including restaurants and free drinks. It can also feature stage shows and dramatic scenery. Some casinos have become so famous that they are synonymous with the name of the city where they are located, such as the Bellagio in Las Vegas and the Monte Carlo in Monaco.

Because large amounts of money are involved, casino security is a major concern. Staff members are trained to watch for blatant cheating (palming, marking cards, switching dice) and keluaran sgp suspicious betting patterns. Elaborate surveillance systems give a high-tech “eye-in-the-sky” view of all the gaming rooms at once, and they can be adjusted to focus on specific suspicious patrons.
