Here is the list of the most amusing myths concerning slots.
You can spot a winning slot machine.
The only way one can say that theslot machine is a winning one is only to catch this moment, when the machine pays out. Slot machines use random numbergenerator and that's exactly that. Random.
Casinos place loose slots near the cashier, aisle ways, etc.
If this were true, it would be the only machines anyone would play. A casino mixes slots all over the casino floor. No one with any experience at playing slots would make a statement like this.
Count the number of symbols on the reels to determine your odds.
This is mathematically impossible, remember the RNG (random number generator) determines the stops. Thereare literally millions of combinations on a 3 reel slot machine, so there is no way of determining odds by the symbols on the reels alone.
Casinos can tighten or loosen slot machines from the back office.
In order to change how a slot willpay out is by changing the computer chip. No casino can just flip a switch.
A slot machine that has not been paying is due to hit.
Absolutely false. The RNG assures this. You have an equal chance of winning on a losing machine as you do on a machine that just paid out the jackpot.
Pulling the slot machine handle produces more wins than pressing the spin button and visa versa.
It is also a mistake. These things are only mechanisms for beginning the game. The machine knows whether you win or lose before the symbols begin to stop.
Playing with hot coins improves your chances.
Once again, the computer determines a win or loss and the temperature of the machine or moneyirrelevant. Although it's funny that people still burn their fingers with lighters believing this works.
Casinos set slot machines to payback more on the weekends.
Wrong again. Your odds of winning are the same no matter if it's 4:00pm Monday, 8:00pm Saturday or 3:00am Wednesday. Casinos can not and do not do this.

Knowing the rules is of great importance when playing any casino game. Slots are the easiest casino games. The rules are very simple. The player has to insert coins in the slot machine, then push the button or pull the handle and wait for the combination of symbols. 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. All the player has to do is drop coins in the slot and pull the handle or push the spin button. The main objective is to match certain symbols on the paylines. But the player can do nothing to affect this. 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. What you can really doubt is the honesty of some manufactures.
The very first slot machines worked according to the following principle: the wheels spun and then each of them stopped randomly. Modern slots are much different. Now the integral part of any slot machine is a chip, which is programmed to select numbers randomly. The selected number determines the symbol which then comes out. 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. Inspectors look at brands of machines and their chips before they are installed in casinos, but they can’t inspect each machine. If inspectors approve the brand, they can produce machines, and change them. But these changes must cover legal requirements. Some dishonest manufactures use the right to produce machines, but use a different chip, which is programmed to pay less or not so often.
There is an example when there was inserted an illegal tip which doesn’t allow royal flushes. Or a chip that shows near misses of a jackpot. One the one hand the machine would never have a jackpot and the player would keep on playing. If you think you’re playing a machine that is not honest, you can 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.

There is a man who 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. His next invention was a slider, a guitar wire. He inserted it into the machine, which released coins form the hopper.
When the slots were computerized he needed a new tool. He fooled a manufacturer into believing he was a customer and showing 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 good thing will end one day. Tommy was caught using his invention in one of the casinos. 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.
