What Is a Casino?

A casino, also known as a gambling house, is an establishment for certain types of gambling. Modern casinos are like indoor amusement parks with a wide variety of games such as black jack, roulette, craps, keno and slot machines. They also offer shows and fine dining to make the experience more pleasurable for patrons. They are known for bringing in billions of dollars in revenue each year.

There is one certainty in gambling: the house always wins. Casinos have built-in statistical advantages for all games that allow them to turn a profit. The advantage can be a small amount, such as less than two percent, but the millions of bets placed by patrons allow casinos to build fountains, towers and replicas of famous landmarks. In addition, the vig or “rake,” which is taken by dealers in card games and by video poker machines, contributes to a casino’s profitability.

While gambling probably predates recorded history, the idea of a casino as an entertainment center came about in the 16th century during a gambling craze among European nobility that led to the development of private gaming clubs called ridotti. While these clubs were technically illegal, they were rarely bothered by authorities. Modern casinos usually employ a combination of physical security forces and specialized surveillance departments. This allows them to maintain a safe environment and to quickly respond to suspicious or definite criminal activity. Something about gambling seems to encourage people to cheat or steal, either in collusion with each other or on their own.
