What Is a Casino?


A casino is a place where a variety of games of chance are played. Slot machines, black jack, roulette, craps and keno are the main gambling activities that bring in billions of dollars to casinos every year.

Security is a major concern for the casino industry. The rules of many casino games follow certain patterns, and the movements and reactions of players are watched carefully for any atypical behavior.


In the past, people used to gamble and play games of chance in private homes and other public venues. But in 1638, Venice opened the Ridotto, a gambling establishment that was a government sanctioned space to play games. The casino featured a variety of primitive games of chance and provided food and beverages for customers.

The Ridotto was the first government-sanctioned gambling house and it is considered the birthplace of modern casinos. It was followed by a boom in gaming buildings throughout continental Europe. In the 18th and 19th centuries, places like Baden-Baden and Monte Carlo began to build elaborate casinos that were designed for the rich and privileged.

Because casinos handle large sums of money, they face a special threat from theft by guests and staff. To mitigate this, casino security teams invest heavily in surveillance technology. They use sophisticated sensors that can detect threats in real time without requiring guests to stop, empty their pockets, or open their bags. This keeps casinos safer while also reducing the wait times that could discourage guests from visiting.

Aside from the surveillance technology, casinos also employ a variety of physical security measures. Some of these include a team of highly trained security officers who patrol the premises and respond to calls for assistance and reports of suspicious behavior. In addition, some casinos have specialized security departments dedicated to specific types of casino games. These specialized security teams are trained to recognize specific betting patterns and other suspicious behaviors.
