Many European countries have made casinos legal by updating their laws over the past century. In the United Kingdom, licensed gambling clubs have been operating since 1960, but they require membership. France legalized casinos in 1933. There are now many famous European casinos in France. Security measures in a casino involve surveillance and routines. Security guards watch every table, window, and doorway. Cameras can be adjusted to focus on patrons who appear suspicious. Video feeds are recorded and reviewed later. Computer chips are embedded in casino machines and determine what machines will pay. This makes it easier for security guards to identify suspicious behavior. But, despite these measures, people still manage to lose in a casino. So, the best way to avoid becoming a victim of gambling is to know how to stay safe. The house edge of a casino is higher the longer you play, the more likely you are to lose. This strategy is intended to make you insolvent. It is, therefore, a good idea to restrict the time you spend at casinos. Most games in casinos are designed with the house's advantage in mind.
