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. 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.
It is a rude mistake. RNG decides when the machine will stop and there are thousands of combination available on a 3 reel slot machine.
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.
One more rude mistake. The chances and odds are always the same. It doesn’t matter when you play.

Every casino game has its own rules, features and of course etiquette. Slots are not an exception here. Though slots are played by one person, still thinks which can and can’t be done during playing slots. First of all decide whether to deal or not to deal with this very slot machine. It can be difficult for the solo slot player to save a machine when they go to the rest room or to get a drink, but there are signals that can be used to indicate that a machine is in play. The most commonly accepted signal is to hang a coin cup over the handle of the slot machine. Placing the coin cup on the seat has the same meaning. If you play in the casino that uses a cashless system you can just leave the jacket or one of your belongings on the seat. In your turn you should respect other players and never sit to a slot that is in play. The second tip has to do with the player card that has been left behind. It happens very often that a player leaves his card and walks away. The accepted way to deal with this situation is to place the player card on top of the slot machine where it can be easily seen and retrieved. While most casinos do allow smoking, it is important for those who smoke to be courteous to others, and to position the ashtray in a manner which inconveniences other players the least. The last etiquette rule is tipping a person, who brings you the winning. For jackpots that require a hand payout, the customary tip is one half of one percent of the jackpot.

It is true that slots are designed to be honest and not to deceive a player. But there are some manufactures that design the slots in such a way that they can deceive players.
When the first slots only appeared cheating was impossible because they worked mechanically, with independent wheels spinning and then stopping randomly. Modern slot machines differ form the old ones greatly. 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. 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. 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. 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.
In one of the casinos the chip was programmed in such a way that royal flushes would never come out. Similarly, Universal Distributing Company was caught programming machines to show a “near miss” of a jackpot. The player would never hit a jackpot but keep on playing maximum bets. If you think that you have come across such a machine you have a right to complain. Be sure that inspectors will examine this very machine and the casino itself to make sure everything is ok. Manufacturers that cheat are fined or they can lose their license.

There is a man who managed to cheat slots.
Slot machines pay on a random basis, but what if you could improve the payout a little? Would you do it? Tommy Glenn Carmichael would and did.
A 53-years Tommy all his life tried to invent some kind of devices to cheat the slot machine. His first invention worked, but not for a long period of time as he was sentenced to prison for using it. 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. In some way he managed to fool the manufacture who showed him the inner construction 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. Carmichael marketed these wands to other slot cheats, making as much as ,000 a day. Now he could afford the most expensive cars and several houses.
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.
