A casino (also known as a gambling house or a gaming hall) is an establishment for certain types of gambling. Most casinos are located in cities with large populations, especially those on or near the coasts. They are also sometimes combined with hotels, resorts, restaurants, retail shops, and/or cruise ships. Live entertainment is often a feature of these venues. Examples of such entertainment include stand-up comedy, concerts, and sports events.
A number of modern casino games have roots in ancient civilizations. Evidence of gambling dates back to 2300 BC in China; dice appeared in Rome around 500 AD, and card games followed soon after, including the game that would become blackjack.
When the first Nevada casinos opened in the 1950s, organized crime figures had lots of money to invest. They took sole or partial ownership of some casinos, and used mob connections to influence results at others. This tainted the reputation of these enterprises, and eventually led to federal anti-mob laws that prohibit the use of gangsters in the operations of American casinos.
Today, casinos are more sophisticated than ever before. They use technology to monitor all aspects of their operations, including “chip tracking” devices that allow the casino to know exactly how much is wagered minute-by-minute, and to detect any deviation from expected results. They also use video cameras to record player behavior, and computer systems that can “read” the patterns of play on a roulette wheel or card deck to discover any anomalies.
