What Is a Casino?

A casino is a place where people gamble on games of chance. Many casinos also feature restaurants, free drinks and stage shows. While some places have more luxuries than others, there is no such thing as a “bad” casino. In fact, it is rare for a casino to lose money on any particular day, because every game has a built in statistical advantage for the house. This advantage is usually very small – less than two percent – but over time it adds up. Casinos typically earn money by taking a commission from some of the money bet by patrons, a practice known as vig or rake.

The most famous casino is in Las Vegas, but there are many more around the world. These include the elegant spa town of Baden-Baden, which first opened its doors to European royalty and aristocracy 150 years ago. Its Belle Epoch architecture was inspired by ornate French palaces, and it has been described by German actress Marlene Dietrich as the most beautiful casino in the world.

Modern casinos employ a combination of physical security and specialized surveillance departments. The former patrols the facility and responds to calls for assistance or reports of definite or suspicious criminal activity. The latter operates the closed circuit television system – known as the eye in the sky – that watches all of the tables and windows from a room filled with bank of security monitors. Statistical deviations from expected patterns are easily spotted by these sophisticated systems, which are often wired to an expert group of gaming mathematicians and computer programmers.
