A casino is a gambling establishment where gamblers wager money or other valuables on games of chance, the outcome of which is determined by the laws of probability. A casino may also offer entertainment and other amenities to its patrons such as restaurants, bars, and luxury accommodations.

In the United States, casinos are usually licensed and regulated by the state where they are located. Historically, many states have prohibited casino gambling, but in the 1980s and 1990s, several changed their laws to allow it. Casinos are also found on American Indian reservations, which are not subject to the same state antigambling laws as are commercial casinos.

Casinos use a variety of security measures to protect their customers and property. These include cameras, secure entrances, and security guards. Some casinos also use sophisticated technology to monitor their games, including “chip tracking” systems that record betting chips’ movements, and electronic monitoring of roulette wheels to detect any deviation from expected results.

The glitz and glamour of casino resorts have made them the destination of choice for many visitors, with opulent furnishings and overflowing bars to lure in gamblers. While most casino resorts offer a wide selection of games, some stand out for their size and other amenities.
