A casino is a gambling establishment. The term may also refer to an establishment that hosts live entertainment events.

A casino features table games like blackjack and roulette, as well as video poker and slot machines. Some casinos also have restaurants and bars. The atmosphere is designed around noise, light and excitement. In addition, some casinos are famous for their extravagant decorations and architecture, such as fountains, towers and replicas of famous landmarks. Casinos are usually located in tourist areas and serve as a central hub for a resort or vacation destination.

While gambling likely predates recorded history, it didn’t become a popular pastime until the 16th century when a craze for the game spread through Europe. At that time, wealthy Italian nobles would hold private parties at their homes called ridotti where they could gamble away their fortunes without being bothered by legal authorities [Source: Poley].

Casinos make money by charging players to play the games. Each game has a built-in advantage for the casino, often lower than two percent, which is enough to cover overhead and other costs. In addition, some casinos use a strategy of “comps” to reward loyal patrons with free hotel rooms, buffet meals, show tickets and limo service.

Despite the glitz and glamour of casino gaming, critics point out that its effect on a community is mostly negative. They contend that casino revenue draws away spending from other forms of local entertainment and that the cost of treating compulsive gamblers can offset any economic gains casinos might generate.
