Modern casinos employ elaborate security systems and procedures to prevent cheating and theft. For instance, cameras on the ceiling and at every table monitor each patron. The cameras can be adjusted to focus on specific patrons if a suspicious situation arises. Video feeds are recorded and reviewed later. Casinos also have computer chips that determine the payouts on slot machines.
The casino’s edge in the games they offer is very small, sometimes less than two percent. However, the casino earns enough money from these games to build lavish hotels, giant pyramids, and towers. This advantage is known as a “rake” or “vig”. The casino’s edge may vary, depending on the game played.
Throughout the European continent, the casino concept spread. The most popular games of today were invented in France. In Italy, the casino began as a club for wealthy Italians. But as large public gambling houses closed, the gambling trend moved to smaller venues. Nevertheless, European casinos are home to some of the most renowned casinos in the world.
Some players may resent the casino’s attempt to change their luck. They may feel that the new dealer is using a technique that will “cool” the game.
