Throughout the years, gamblers have tried to cheat casinos in many ways. Some are quite innovative while others rely on common sense. One of the most popular ways to gain an edge is by using hidden cameras and earpieces. These devices let them see what the dealer does at a blackjack table or baccarat and relay this information to their partners.
A magnet is another very common way of cheating. This is a low-tech method and can be used by anyone who can afford to spend some money on a strong magnet. It’s a risky method, as holding a strong magnet will attract the attention of casino security.
Some players have even tried to “yoyo” a penny into a slot machine laser sensor. This trick worked until optical sensors were improved by manufacturers. Other cheaters would tie a string around their coin, then yoyo it in the slot to fool the sensor.
Fortunately, these types of cheating devices are no longer being used in the modern gambling industry. Gaming companies use SHA-3 encryptions in order to make sure that no one is able to change the code without being detected. The quality of the high-end poker cheating device indicates that there is an active and profitable black market for these devices.
