What Is a Casino?


A casino is a gambling establishment, usually built in or adjacent to hotels, restaurants, retail shopping, cruise ships and other tourist attractions. Casinos are most often associated with gambling, but some also offer live entertainment, such as comedy shows or sports events. Casinos vary in size, and some have a themed design. In the United States, the most popular casino games are poker, blackjack, and roulette.

Because casinos deal with large amounts of money and have a high volume of traffic, they must spend a great deal of time and energy on security. The security measures include cameras that monitor every table and window, allowing casino personnel to quickly identify suspicious patrons. There are also elaborate “eyes-in-the-sky” systems that allow security staff to watch all areas of the casino simultaneously.

In the twentieth century, the casino industry grew to become a massive business enterprise. Real estate developers and hotel chains, recognizing the potential profits, bought out the mob owners and established legitimate businesses. In addition to the normal gambling operations, casinos now feature an ever-increasing range of amenities and services designed to attract and keep customers.

While musical shows, lighted fountains and lavish hotels help to draw people to casinos, most of the revenue generated comes from gambling. While casinos may offer a wide variety of games, the one constant is that a casino’s house always wins. Casinos use mathematical odds to ensure this outcome and have built-in advantages that guarantee the house will win the majority of bets.
