There are 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. Just a second and the coins will be flying all over the casino!
The player will play until the machine pays out. He must have found a machine that haven’t paid for a long period of time or he has inserted to many coins and has got nothing. They believe that a big win is sure to happen right now. The rush is that if they leave after depositing so much money in the machine it will erupt and the payouts will be often and large. Maybe it can really work if you have already spent thousands of dollars and have got nothing back. The machine must pay.
Many years ago players have their own way of determining whether the machine has not paid out for a long period of time. They touch the coins to see whether they were cold or hot. If the coins where hot then the slot machine had not paid out in a while and to the chaser this was good as the machine was do. But in reality any machine has numerous lights which heat the coins.
Chaser is the next type of slot players.
The player thinks that the machine he is going to play is not a machine that never pays. The player have won and being reinforced by the win gains trust in the slot machine. One can feel the atmosphere of comfort and trust between the machine and the player.

Slots Rules: Understanding the rules of the game is always important, no matter what game you are playing. With slots the rules are very simple: Read the payout chart, insert coins, push button, (or pull handle), insert more coins. If you hear bells ringing and see lights flashing it means that you win. Of course you can win much, but never bet or spend more than you can afford.
Rules for playing Slots
Only slots have so simple rules. There are no real rules. The principle of the game is the following: the player inserts coins, pulls the handle and then checks the combination of symbols on the lines. The mission of the game is to match preselected symbols on the pay line, (or paylines, depending on the machine being played, there can be up to 5 pay lines on some machines), to earn credits. Slot machines can be found in many denominations from 5 cents to being the most popular, although there are also machines that accept 0 tokens.
Especially beginners like slots. They don't have to worry about rules and regulations, or being laughed at by the other players for making a bad play, all they have to do is try to hit the jackpot by matching the highest paying symbols on one of the pay lines.

It is true that slots are designed to be honest and not to deceive a player. However, in the past certain manufacturers have been caught using computer chips that cheat the customer.
When the first slots only appeared cheating was impossible because they worked mechanically, with independent wheels spinning and then stopping randomly. Modern slots are much different. Now the integral part of any slot machine is a chip, which is programmed to select numbers randomly. After selecting a number a corresponding symbol appear on the screen. There is a computer code. It generates the random numbers and determines whether the slot machine is loose or tight. The gaming inspector will examine the machine to make sure it will not deceive the player. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
It is next to impossible to say whether the chip is programmed not in a right way because the machine is not supposed to pay out with every spin. The machines have to be examined before people begin to play them. Of course it is very difficult to examine every single machine, that’s why inspectors examine only brands. In the case of the approval of the brand the manufactures can produce the slot machines, even change them if it doesn’t go out legal bounds. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
In one of the casinos the chip was programmed in such a way that royal flushes would never come out. Or a chip that shows near misses of a jackpot. The effect was two-fold: the machine didn’t pay off, and customers continued to play the machine, thinking that they were very close to a big jackpot. If you think that you have come across such a machine you have a right to complain. In the case if the complaint the inspectors will visir the casino and check whether the machines have a legal chip. Manufacturers that cheat are fined or they can lose their license.

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.
Tommy is now 53 and he can be said to have spent all his life inventing different devices to cheat slot machines. His first device was a kind of a top-button joint. By the way, for this device he was sent to prison. After the release Tommy began to invent new kinds of devices for cheating slot machines. For example, he invented a tool called a slider made from guitar wire that he used to insert into the machine and trip a switch, which released coins from the hopper.
Later, as slot machines became computer based, he had to invent a new tool. Tommy found a manufacture who showed him the inside of a slot machine. It was enough to learn everything that he wanted. 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. With all this money he bought expensive cars, houses and what not.
Eventually, all good things come to an end. 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 that time the police already have all necessary clues to prove that Tommy was guilty. He got three years’ probation and lost everything that he had bought before. He has been banned from entering any casino.
