A casino is an establishment for certain types of gambling. The precise origin of gambling is unknown, but it has long been a part of human culture. Gambling is a popular past time and can be seen in many societies throughout the world. It is usually associated with luck and fate, but also involves skill and knowledge. Casinos are usually located near or combined with hotels, restaurants, retail shopping, cruise ships, and other tourist attractions.
In modern casinos, computerized technology is routinely used to monitor games in progress. For example, betting chips have built-in microcircuitry that interacts with electronic systems in the table to allow casinos to oversee exact amounts wagered minute by minute and warn them of any anomaly; roulette wheels are electronically monitored regularly to discover quickly any statistical deviation from their expected results; and slot machines are constantly wired to a central server so they can be adjusted for any desired profit margin.
Among the most famous casinos in the world is the Casino de Monte Carlo in Monaco, which has been a premier center for European gaming since its establishment 150 years ago. Less well known but equally elegant is the Casino at Baden-Baden in Germany, which first opened its doors to royalty and aristocracy almost a century ago. A number of smaller places have become famous for their casinos, notably Las Vegas and Atlantic City in the United States, as well as Macau in Asia.
