The term “Casino” originally meant a small villa, summerhouse or pavilion built for pleasure, usually on the grounds of a larger Italian villa or palazzo. There are examples of such casinos at Villa Giulia and Villa Farnese. In modern day Italian, this term designates a bordello (also called “casa chiusa”, literally “closed house”), while the gambling house is spelled casinò with an accent.

A casino is, in the modern sense of the word, a facility that houses and accommodates certain types of gambling activities. Casinos are most commonly built near or combined with hotels, restaurants, retail shopping, cruise ships and other tourist attractions. Some casinos are known for hosting live entertainment events, such as stand-up comedy, concerts, and sporting events. One of the first known casinos was established in Venice around 1638.[2] During the 19th century, the term “casino” came to include other public buildings where pleasurable activities, including gambling, and sports took place. An example of this type of building is the Newport Casino in Newport, Rhode Island.

A locals casino is a casino designed primarily to attract residents of the area in which it was built rather than tourists or vacationers. The term is most commonly associated with casinos in Nevada, USA to distinguish them from casinos that target mostly tourists.
