Online Slot Machine Cheats

Of course, new online slots cannot be cheated as they are online and the results are completely random. This is ensured with the use of a Random Number Generator. However, in the past, some shady people have managed to figure out ways that they can cheat the slots in a casino. However, nowadays casinos know what to look for in order to catch and prevent these cheats from occurring.

Coins On A String

This is perhaps the simplest of all the methods that we will outline here at Wizard Slots. It just involves a string attached to a coin. Quite simply, the cheater would insert the coin and ensure that the credit was registered on the slot machine. Then, when the spin had begun, they would pull the coin back out in order to use it again. This method was discovered when in a book called “Slot Machine Drama”, Dwight and Louise Crevelt recounted that they were playing slots when it jammed. Upon calling a technician to fix it, they discovered a coin with a nylon string threaded through the hole. This must’ve been from the previous player who had actually lost their coin. Nowadays, however, this ‘trick’ does not work on newer machines due to the fact that newer machines do not accept coins as wagers and they do not pay out in coins.

Foreign Coins

In 1980s Nevada, slot cheats took advantage of the production of washers that were exactly the same weight and size as American coins. These coins were subsequently found all over the state in various slot machines. This was the same of foreign coins that were actually found in slot machines also and had been accepted as a higher value than they were really worth. Mexican one peso coins were the most infamous amongst casinos in 1985 as they were accepted in the machine as 25 cent pieces.

However, this cheat also stopped working when the production of modern slot machines began as they do not accept coins, but instead only accept notes in the machines. Even then, the casinos are consistently diligent in ensuring that all notes are scanned in order to validate them before allowing them to be exchanged for credits.

Magnet Cheats

Today, you may look a bit weird walking around the casino holding a large magnet with the intention of attempting to ‘grab’ any coins determined by the reels. However, these days, slot machines are thoroughly protected from external magnetic fields. The method also does not work because payouts are no longer generated by the reel symbols but a random number generator. Therefore, if a jackpot combination shows on the reels but not on the RNG, then the casino does not have to pay you.

Filling The Machine

Casino employees were the ones that benefitted from this cheat. Not for long, though, as they were caught and arrested. When filling the slot machines, employees could keep a hold of some coins in the bag so that the machines were only a few coins down. An honest mistake, right? Wrong. Employees would then be a few coins up every time they filled the machines and over time, this would amount to quite a large amount of money.

Climb Inside The Machine

This is the most obvious of all of the cheats on the list but was also the most difficult to get away with because of the fact that you have to physically climb into the machine without attracting the attention of the security guards. You then have to be able to manipulate the reels in order to win the slots.

The Monkey Paw Cheat

Tommy Glenn Carmichael was the most infamous for creating devices that essentially allowed him to ‘hack’ new electronic slot machines into paying out. The Monkey Paw was created to allow the player to receive payouts without even wagering. It was made out of a guitar string and a metal wand that would be threaded through an air vent to trip a switch that triggered a payout.

Carmichael functioned in casinos and developed these devices for nearly 40 years. However, he was eventually caught, arrested and had 2 of his homes seized. Following his stint in prison, he began to help the Nevada Gaming Commission to stop people cheating in Las Vegas casinos. He did this by developing “The Protector” that prevented devices like the ones he made from being put into the machines.

The Light Wand

This was a device that was also developed by Carmichael which was developed about slot machines began to use Random Number Generators for electronic slots. New slots were tripped by an electronic sensor rather than a physical switch. The light wand worked in a way that it would be put into the payout chute where all the coins would pool. Then the light would set the sensor off and therefore issue a payout.


No, this is not a hug but is instead a way that cheaters thought they had beaten the casinos. In old slot machines, payouts were paid by coin tubes. The coins would pool into the tubes and whenever someone would win, the slides at the bottom of the tube would open and distribute the amount needed.

Cheaters took advantage of this and would manage to insert a spoon into the tube that would keep the slide open. Subsequently, the tube would drop all the coins that it was holding. This worked for a while but it was also prevented with the production of new slot machines.
