What Is a Casino?

A casino (from Spanish: caada) is a large building or room where gambling games are played. Casinos are often built near or on waterways to take advantage of the natural ebb and flow of water, which provides easy access for ships carrying cargo or passengers. Casinos also often feature entertainment venues such as theatres and concert halls.

A number of different types of gaming are featured at casinos, including table games like blackjack and roulette, as well as video poker and keno. Some casinos offer sports books and race tracks, while others focus on catering to high rollers with luxurious suites and other amenities. A casino’s profitability depends on its ability to attract and retain customers, and it is therefore common for them to offer free or reduced-fare transportation, hotel rooms, drinks and cigarettes while gambling, and other incentives.

Despite their differences, all casino games have one thing in common: they involve risking money or property on random events. Because of this, casinos are a prime target for both patrons and criminals who may attempt to cheat or steal, either in collusion with a casino employee or independently. To combat this, modern casinos usually have a physical security force as well as a specialized surveillance department.

Gambling in all its forms has been a part of human culture for millennia, with evidence of dice-rolling dating back to 2300 BCE and card-playing starting around 800 AD. The first modern-day casinos opened in the mid-20th century, with many appearing on American Indian reservations, which are exempt from state antigambling laws.
