There exist at least two types of slot players.
The first type is a persistent player.
The players of this type believe that very soon there will be a period when the machine begins to pay. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
Players become so persistent if they have already spent a lot of money for this slot and haven’t got anything or if they have found a slot machine that haven’t paid for a long period of time. They know the next big win, or any win is due to pay out. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Makes sense if you have lost 0. 00 and have yet to win. The machine must pay.
In the old days when a payout occurred players would feel the coins to see if they were hot or cold. If the coins were hot they believed that the machine had not paid for a long period of time. In fact the coins could be hot only because of the numerous lights that heated the coins.
Chaser is the next type of slot players.
The player believes the slot machine is not one of those machines that never pay. Players feel more comfortable and confident because they have been reinforced with a win and gain trust in the machine. One can feel the atmosphere of comfort and trust between the machine and the player.

Have you ever met a man who has managed to cheat slots?
It is impossible to cheat the slot machine, but to improve the payout is possible. It was proved by a gambler whose name was Tommy Glenn Carmichael.
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. 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.
When the slots were computerized he needed a new tool. Tommy found a manufacture who showed him the inside of a slot machine. It was enough for Tommy. 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. 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.
