A casino or gambling house is an establishment where people can take part in gambling activities. Casinos usually offer a variety of gambling games and are also found combined with hotels, restaurants, retail shops and cruise ships. Casinos are regulated by government and are designed to protect their patrons. Casino security personnel use cameras and other technologies to monitor casino gambling activity. In addition, casinos enforce rules and regulations that prevent cheating and fraud.
Casinos earn money by charging a percentage of every bet placed to their game hosts or house managers. This is commonly known as the “vig” or “vigorish”. The amount varies between games but is usually higher for table games than for slot machines or video poker. This vig makes casinos the most profitable entertainment businesses in the world, enabling them to finance elaborate hotels, fountains, pyramids, towers and replicas of famous landmarks.
Many Americans have gambled in a casino at least once in their lives. As of 2008, 24% of Americans had visited a casino in the previous year. This figure compares with 20% in 1989.

In addition, some casinos feature Far Eastern games such as sic bo, fan-tan and pai gow. These games are often played on specialized tables that require skill and practice to play well. Many casinos hire gaming mathematicians and computer programmers to analyze the mathematical probability of winning at each game.
