The most important aspect of any casino is the security. Security begins with the employees. Dealers are trained to look for signs of cheating, but they aren’t always the best. They need to focus on their game to identify patterns of betting. Table managers and pit bosses monitor all of the tables to ensure that no one is cheating or abusing the games. Each employee of a casino has a higher-up that is monitoring their activities.

During the 1990s, casinos began increasing their use of technology to protect patrons. Today, casinos routinely monitor gambling activities with video cameras. They use “chip tracking” technology, which involves betting chips that have built-in microcircuitry, which enables them to watch each player’s wagers minute-by-minute. The roulette wheels are also monitored for statistical deviations. Some casinos even offer free cigarettes and drinks to big bettors.
