What is a Casino?

A casino is a gambling establishment that offers games of chance for the enjoyment of its patrons. It makes a profit by taking a percentage of each bet or charging an hourly fee for each game played. A casino may also offer free drinks and cigarettes while patrons are gambling. Casinos are most famous for baccarat, blackjack and the various poker variants, although they may also offer roulette, craps, keno and other games.

The word casino has its origins in the Italian city of Casin, meaning “little castle.” In the Middle Ages, the term referred to a tavern with a gaming room. The modern casino is essentially a large entertainment complex, with music and light shows, shopping centers and elaborate themes to draw in the customers. But it wouldn’t exist without the games of chance that provide the billions of dollars in profits raked in by casinos every year.

There is one certainty about casino gambling: The house always wins. That’s why casino managers and owners are so adamant about security. Cameras provide an eye-in-the-sky view of the entire floor, allowing security workers to quickly check each table, change window and doorway for signs of suspicious activity.

A more subtle method of security is to enforce rules of behavior. Dealers watch patrons carefully and can spot blatant cheating by palming cards or marking dice. Pit bosses and tables managers can also keep an eye out for betting patterns that indicate a cheating gambler is on the way to winning.
