A casino is a place where people can play games of chance. These include slot machines, roulette, baccarat, blackjack, and craps. These games generate billions of dollars for the casinos, hotels, resorts and Native American tribes that own and operate them.

Casinos are often built near or combined with hotels, resorts, restaurants, retail shopping and cruise ships to attract visitors. Some casinos also host concerts, sports and other forms of live entertainment.

Gambling History

It’s not clear when or where gambling began, but it almost certainly predates the establishment of casinos. Italian aristocrats may have gambled in private rooms known as ridotti, but it was not until the 16th century that gambling became popular as a leisure activity.

Gambling Today

In modern times, casino gambling is legalized in many states across the United States. The number of legal casinos is rapidly increasing, fueled by the demand for tourism and interstate competition.

Game Selection

In addition to games of chance, most casinos offer a variety of table and card games. These games usually have a built-in advantage for the casino, called the house edge. This edge makes sure the casino always wins in the long run.


Casinos employ a number of employees to keep track of all of the gambling activities taking place inside and around their buildings. These include dealers, pit bosses and managers of table games. They all have a wide perspective and are trained to spot cheating by looking for palming, marking cards or dice and switching cards.
