Have you ever met a man who has 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. He was caught with one, called a top-bottom joint, and sentenced to prison. Then he was released, but continued to work at inventing devices for cheating a slot. The principle of his next invention was following: he inserted a guitar wire in the slot machine and it made the coins release from 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. He fooled a manufacturer into believing he was a customer and showing him the inside of a slot machine. From that experience, he learned what he needed to know to beat it. His new inventions was a light want that blinded the sensor of the slot machine and as a result got winnings. Other gamblers liked his invention and he had a lot of customers, which allowed him to earn up to ,000 a day. He drove expensive cars, took cruises, and bought two houses.
But as known good things can’t last forever. For Carmichael, they ended in front of a slot machine at Circus, where he was caught with the light wand when he tried to run from security. While charges from that incident were later dropped, he was caught under similar circumstances in Laughlin and later Atlantic City. By this time, authorities had tapped his phone and recorded conversations with other cheats who used his device. He served three years’ probation and lost both homes. He has been banned from entering any casino.
