What Is a Casino?

A casino is a building or room where gambling games are played. Its name is derived from the Latin casino, meaning “little house.” The casino has always had an ambivalent relationship with society and it is not uncommon for gamblers to be barred from entering casinos, and casinos in turn have been blamed for damaging local neighborhoods. This has led to attempts at regulation and even a few casinos being closed down.

The opulent spa town of Baden-Baden in Germany’s Black Forest first became a playground for Europe’s royalty and aristocracy 150 years ago. It’s still a destination for those with a taste for the glitz and glamour, with elegant poker rooms and a plethora of blackjack, roulette and slot machines.

While gambling is the centerpiece of many casinos, most also have restaurants, bars, clubs, shows and other entertainment. They are usually built in a prominent location and are easily recognized, with signs that flash bright lights and feature images of popular games.

Most modern casinos rely on technology to monitor their patrons and games. In addition to video cameras, they use chip tracking to supervise all betting actions minute by minute, and to alert them to any statistical deviations from expected results. The mathematicians who perform this work for casinos are called gaming mathematicians or analysts. This information is important for a casino to have, as it helps them estimate how much profit they will make from each game and determine how large a cash reserve they will need.
