A casino is a place where gambling activities take place. It can also be a venue for live entertainment or a resort with top-notch hotels, spas and restaurants. Casinos are often associated with a particular region or country, and some even feature theme parks.
Gambling is an activity that probably predates recorded history, with primitive protodice and carved six-sided dice among the earliest archaeological evidence. However, the modern casino as a place to find a variety of ways to gamble under one roof did not appear until the 16th century, when a gambling craze in Europe made its way across the oceans to Italy, where wealthy aristocrats gathered at private clubs called ridotti. 
The popularity of these venues eventually spread to other countries, and many casinos are located outside the United States. The largest concentration of casinos is in Nevada, with more than half of the industry’s revenues coming from this market. Atlantic City and New Jersey, as well as Iowa and other state-licensed locations, also have a significant presence in the industry. Many Native American casinos have opened in recent years, and they are responsible for some of the industry’s fastest growth.
Gambling games make up only a small part of the overall appeal of a casino. Today, a casino may offer everything from a simple bar to an extravagant hotel and spa. Some are historic and charming, while others are sleek, modern temples of indulgence. Whatever the case, a casino is meant to be enjoyable for everyone who enters.
