A casino is an establishment for gambling. In its broadest sense, it can also refer to a place where entertainment events and shows are held. It can be located within a hotel or in a separate facility, and it may offer multiple types of gaming. Casinos are also known for serving alcohol and for their colorful decoration and noisy, exciting atmosphere. They are often combined with restaurants, hotels, retail shops and other tourist attractions.

Some casinos have a reputation for being crime-ridden, but that is not always the case. Most major cities with casinos have a large number of police forces to maintain law and order. Several casinos have been owned by the mob, but federal crackdowns and the fear of losing a casino license at the slightest hint of organized criminal activity have kept the mob out of most casinos.

In addition to security personnel, casino patrons are often watched by other employees. Dealers can spot blatant cheating (palming, marking or switching dice), and table managers or pit bosses watch over the larger games with a broader view of the patrons to make sure no one is stealing money from the casino.

Casinos try to lure customers with a variety of promotions and bonuses. Free food and drinks, hotel rooms and tickets to shows are offered to big gamblers. Some casinos are even open 24 hours, and they serve alcohol at all times. The loud, dazzling lighting and brightly colored floor and wall coverings are meant to stimulate the senses and keep the customers’ attention.
