A casino (American English), also known as a gambling house or a gaming establishment, is a place where people can play various games of chance for money. These establishments are often combined with hotels, restaurants, retail shops and other tourist attractions. In some countries, casinos are licensed and regulated by government agencies.
Casinos are a major source of revenue for many states, cities and tribal governments. They are a popular destination for tourists and locals alike. People may gamble at casino tables, in slot machines, at bingo halls, or at card rooms. Many states have legalized casinos, either on land or through floating facilities like barges and boats. In the United States, there are numerous casinos located in Las Vegas, Atlantic City, and other major cities; many are owned by large corporations or by state-owned Native American tribes.
In the 21st century, some casinos are focusing more on high rollers, a category of patron that spends tens of thousands of dollars or more per visit. These patrons are given special attention and offered comps, such as free spectacular entertainment or luxurious living quarters. To identify potential high rollers, casinos typically offer cards that can be swiped at the table or machine, and they track their spending habits.
Other methods of attracting players include electronic systems that monitor betting chips minute by minute, and video cameras that monitor the games for suspicious activity. Moreover, casinos make use of bright lights and other distractions to keep gamblers on the premises.
