When most people hear the word casino, they think bright lights and big money. They also think about the various games of chance that allow players to try to woo Lady Luck and walk away with a wad of cash. These games include slot machines, blackjack, roulette, baccarat and video poker. Casinos would not exist without these games. They make billions in profits for the owners. This article will look at the history of casinos, some of the popular games and how they work, how a casino stays safe and the dark side of the gambling business.

The first casino, the Monte Carlo Casino in Monaco, opened more than a century ago. It was a playground for wealthy Europeans, and it still attracts royalty and the aristocracy today. Other casinos began to open in Nevada, Atlantic City and New Jersey. Casinos also appeared on American Indian reservations, which were not subject to state antigambling laws.

In addition to the usual security measures such as cameras and guards, casinos employ some very sophisticated technology to monitor their games. In a system known as “chip tracking,” betting chips have built-in microcircuitry that enables casinos to track exactly how much is wagered minute-by-minute and quickly detect any statistical deviation from the expected results. Likewise, roulette wheels are computerized to make sure they do not change the expected results. Casinos also have rules of conduct and behavior that can be enforced by their security staff.
