What is a Casino?


A casino (also known as a gaming house or gambling house) is an establishment for certain types of gambling. Casinos are most often built near or combined with hotels, restaurants, retail shops, cruise ships, and other tourist attractions. They can also be built in or around military bases and on Native American reservations.

Most casino games are based on chance, although some have elements of skill. Casinos spend a great deal of money and time to prevent cheating and stealing by both patrons and employees. This is because casinos handle large amounts of cash and because something about the gambling experience encourages people to try to manipulate the odds to their advantage.

Modern casinos use a combination of physical and specialized surveillance departments to prevent crime. The specialized department operates the casino’s closed circuit television system, which is often referred to as “the eye in the sky”. Casinos also monitor the activity of their patrons very closely and can detect unusual behavior quickly. They can also spot patterns, such as the way a dealer shuffles and deals cards or where players usually place their chips on the table.

Gambling in casinos has a long history in the United States, where it was outlawed until 1931 and then legalized in Nevada. It took several decades for gambling to spread outside of Nevada. Today, casinos are operated by a variety of commercial interests, from real estate investors to hotel chains. Casinos are also a popular source of revenue for local governments, which tax them heavily.
