Computer Chips
Dennis Nikrasch bought a computerized slot machine and played with it in his garage till he found a method to manipulate the computer chip inside to give him a jackpot whenever he wanted. For this purpose, he ordered the standard chips from a real manufacturer. Then he team up to obtain keys on the black market that opened slot machines. After that he would be able to open the machine to replace the chip under three minutes!
04 – Shaved Coins
As slot machine technology advanced, machine manufacturers changed optic verification sensors to prevent scams. Improved mechanisms use a beam of light to register payment as the coin dropped in. Ironically, this innovation was used against itself to perform a cheat. Shaved coins are registered by the machine but once it gets to its comparitor new mechanism which is the piece of equipment that measures the size and weight of the coin, it will be immediately kicked out because of the coins minute size discrepancy. Of course then you can use it again…
03 – Piano Wire
Piano wires
This method dates back to 1982. At the Caesars Boardwalk Regency in Atlantic City, a group of cheaters surrounded a slot machine. Each of them had a job. One of the cheaters dubbed the mechanic, pried open the front and inserted 20-inch piano wires into the slot machine's whirring guts. The group used the piano wires to jam the clock that timed each wheel's rotation. With the help of this method, he was able to manipulate and spin the wheels till he wins.
02 – Monkey Paw
The monkey's paw was one of the early devices used by slot cheats. The mechanism was essentially a guitar or piano string attached to a bent metal rod. Cheater would jam it into the machine through an air vent and fish around for the switch that released the coin hopper.
