Cheating anywhere at anything is really bad and that includes at slot machine cheating. Because majority of the profit of casinos are from slot machines, it is no wonder that slot cheats take this as a golden opportunity. Hundreds of millions of dollars are stolen from various slot machines worldwide due to cheating.
There are many ways that a person can do cheating at slot machines. The old mechanical as well as the electro-mechanical slot machines are the common prey to cheating. Since these types of slot machines mainly operated by gears and pulleys, you will just have to control where the reels should stop to do a successful cheating on them.
Coat Hangers - You can snake a coat hanger into the slot machine that has a mechanical coin counter. With the coat hanger's interference, the slot machine will not be able to accurately cope with the payout.
The Monkey's Paw - It is one of the effective cheating device for slot machines. It is a piece of steel that is flexible, about the length of a ruler, and one of its ends is bent just like a claw. It is inserted into the slot machine payout shaft until the coin counter is reached. The cheating device will interfere thus causing the slot machine to overpay. Today, modern slot machines now have the coin comparator, which checks the tokens inserted if they are valid or not.
Coins on Strings, Counterfeit Tokens, and Shaved Coins - This is a classic fraud used to fool the slot machines. Once successful, the person can now play the slot machine for free or for lesser amount than the specified denomination. Coins on strings are pulled back and forth inside the slot machines to make them think that it is money that's being inserted. Today, slot machine manufacturers have already installed a catch within the machine to stop these cheating strategies.
Mini-lights - This device is used for slot machines that have optical sensors. If the mini-light is turned one close to the light sensor of the slot machine, it will become blinded and will lose track of the coins being paid out. Slot machine manufacturers in recent years have already developed the preventive measure against this cheating tactic.
Sabotage - There are cheats in the past that have managed to institute some flaws into the slot machines even before they are delivered to the casinos. The actual programmer or an inside man is needed to do this. And if done successfully, the slot machine will pay out is a particular pattern in pushing the button is done at a certain time. This is a next to impossible cheating strategy and an ambitious one because everyone who has tried had been caught.
The future of cheating at slot machine is very dim because the machines have less internal gears and are now relying more on computer circuitry. Despite of the many devices invented to cheating slot machines, the casino will still be winner after all.
