A casino is a place that offers a variety of ways for people to gamble. It also offers restaurants, bars and even spas for those who don’t want to play the games. Casinos have a lot to offer for their guests and they are becoming more popular each year.

The origin of gambling is uncertain, but it is generally believed to have been present in almost every society throughout history. Primitive protodice (carved knuckle bones) and dice appear in many archaeological sites, but the concept of casinos as a place where patrons can find a variety of gaming activities under one roof did not develop until the 16th century when a gambling craze spread across Europe. Italian aristocrats often hosted such events in private places called ridotti [Source: Schwartz].

Casinos are a major source of income for the city that hosts them and they attract tourists from all over the world. They may add a variety of other entertainment options to make their establishments more attractive to visitors including art galleries and museums, gyms, pools and spas. However, it is the gaming that draws in the crowds and the money.

Because large amounts of currency are handled within casinos, both patrons and employees may be tempted to cheat and steal. To prevent this, casinos employ a number of security measures. Most casinos have cameras located throughout the premises to monitor activities. Modern casinos have elaborate systems that provide a high-tech “eye-in-the-sky” where surveillance workers can monitor any table, window or doorway from a separate room filled with banks of surveillance screens.
