A casino is a gambling establishment that offers various games of chance, including poker, blackjack and roulette. Some casinos also offer exotic games like baccarat and sic bo, and some have large theatres for live entertainment. In modern times, casinos often employ security measures to prevent cheating or theft by patrons and employees. These measures usually include cameras and other electronic monitoring equipment, as well as rules requiring players to keep their hands visible at all times.

In recent years, the popularity of casino-style gambling has increased significantly, spurred in part by the legalization of casinos on American Indian reservations, which are not subject to state antigambling laws. In addition, casino gambling has spread worldwide. The first major casino was built in the United States in 1978, and by the 1980s many more were opened in places like Atlantic City and Las Vegas.

To play the best casino games online, you want to find sites that use software from leading providers like Microgaming and NetEnt.
