In the 21st century, casinos are not just places to gamble. In fact, the house and banker, who decide whether to win or lose, are omnipresent. In Europe, the concept of casinos began to take hold after nearly every country changed its gambling laws. The United Kingdom, for example, has licensed gambling clubs since 1960. France made casinos legal in 1933, and now has some of the world’s most recognizable casinos. For those who wish to join one, you must sign up for a membership.

In the first centuries, a casino was a large, open-air hall for dancing and music. By the 19th century, it had evolved into a complex of gaming rooms. Monte-Carlo’s casino opened in 1863, and has long been a major source of revenue for the principality. Today, it’s a world-famous tourist attraction. And, of course, there are Trump casinos. However, not all casinos are the same.

Security in a casino starts with the casino employees. Employees monitor the games and patrons while they are playing. Dealers, for example, focus on their own games, so they can spot cheating. Table managers, meanwhile, watch over the tables. They also keep an eye on betting patterns and other potential crimes. Each employee is monitored by a higher-up. In some cases, employees are even monitored by multiple employees. But even if you’re not aware of the surveillance, you can be sure that you won’t walk alone through a casino without protection.
