A casino is a building or large room designed for gambling. It may also be combined with hotels, resorts, restaurants, retail shops, or cruise ships. The name casino is derived from the Latin word for “house” or “familiar.” In some countries, casinos are licensed and regulated by government authorities. They are also known as gaming houses or officers’ mess in military usage.

There are more than 1,000 casinos worldwide. The largest concentration is in the United States, with more than 40 states legalizing casinos. Other popular destinations for casinos include Monte Carlo, Macao, and Singapore.
