There are a lot of myths and superstitions about slots.
You can spot a winning slot machine.
The only way you'll spot a winning slot machine is when the bells are ringing and the money is dropping. RNG is the main element of every slot machine and one never knows what combination it will form.
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.
It is not so. With every game the chances of winning are the same.
Pulling the slot machine handle produces more wins than pressing the spin button and visa versa.
Again false. It makes no difference, as the computer only uses these as mechanisms to start the game. Only the computer determines a win or a loss and it has already determined if you are a winner or loser even before the first reel stops spinning.
Playing with hot coins improves your chances.
It is false. Nothing can affect the outcome, the machine doesn’t care and doesn’t know whether your coins are cold or hot.
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
The rules for slots are one of the simplest set of rules for any casino game. In fact it is so because there are no rules at all. 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. Slots machines have different betting limits. They can be as low as 5 cents and as high as 0.
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.

Slot machines are honest because state gaming commissions make sure they are. However, in the past certain manufacturers have been caught using computer chips that cheat the customer.
The very first slot machines worked according to the following principle: the wheels spun and then each of them stopped randomly. Today’s slot machines are light years away from those lumbering machines of old. There is a chip inside of every slot machine, this chip 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. There is a legal rate according to which the machine has to pay out. Of course it can pay lower, which happen 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. Before the machines are installed in casinos they are examined by inspectors. But you must understand that inspectors can’t examine every machine. They examine the brands. If inspectors approve the brand, they can produce machines, and change them. But these changes must cover legal requirements. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
For example, the Nevada Gaming Commission caught American Coin using chips that did not allow poker 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. Inspectors will respond by pulling the slot machine’s chip and seeing if it is an approved chip. Manufacturers that cheat are fined or they can lose their license.

Meet the man who beat the 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.
A 53-years Tommy all his life tried to invent some kind of devices to cheat the slot machine. His first device was a kind of a top-button joint. By the way, for this device he was sent to prison. Upon his release, he continued to work on the problem and to devise a better way to cheat the new slot machines. 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. In some way he managed to fool the manufacture who showed him the inner construction of a slot machine. It was enough to learn everything that he wanted. 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. He drove expensive cars, took cruises, and bought two 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 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.
