There is a man who managed to cheat slots.
It is not a secret that it is next to impossible to cheat a slot machine. But do you know that Tommy Glenn Carmichael managed to improve the payout of the machine to his benefit.
Carmichael, now 53, had a long history of inventing devices to cheat slot machines. His first invention worked, but not for a long period of time as he was sentenced to prison for using it. Then he was released, but continued to work at inventing devices for cheating a slot. His next invention was a slider, a guitar wire. He inserted it into the machine, which released coins form the hopper.
Later the slot machines were not any longer mechanical, they were computerized and as a result there appeared a need for a new device. In some way he managed to fool the manufacture who showed him the inner construction of a slot machine. From that experience, he learned what he needed to know to beat it. Carmichael invented what he called a “light wand. ” The wand, built with a camera battery and a bright miniature light, was used to shine into the slot machine and blind a sensor, causing the hopper to pay out coins. Other gamblers liked his invention and he had a lot of customers, which allowed him to earn up to ,000 a day. Now he could afford the most expensive cars and several houses.
But as known good things can’t last forever. While using his devise Tommy was caught by the police. He was fined, but soon came back to the same business. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. Three years’ probation and expropriation was the punishment. He has been banned from entering any casino.
