There is hardly any strategy that can be applied to slots. You will probably, of course, encounter someone who claims to have developed thefool-proof' slots strategy system but please, ignore such advice. The outcome of slots is accidental. The slots machine don’t remember wins or loses, they have no memory, so don’t try to overreach them. But there are some tips, which you can use as a basic strategy. Different slots have different payouts. So play slots with the higher payout. You want to find anything above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. Make sure you know the payout schedule before you start pumping in your virtual coins. Determine your losing limit for the day. Stop playing when you reach this losing limit. You will not be a winner every time you play. Don’t think that machine will feel guilty if you insert a lot of coins and get nothing back. Give up the machine that isn’t paying out and is not going to. If the machine pays out good you’d better make higher bets. Don’t make high bets if you are not very lucky with this very slot machine. Find a machine that suits your bank-roll. If you have little money you’d better paly dollar machines. Don't forget to cash out the credits you've accumulated. It may seem strange but some gamblers forget to do it. Try to play the slots or games you have played before.

There are at least two types of slot players.
The first type is a persistent player.
These players are sure that the machine is already ready to pay out, they just have to wait for a little. The machine can begin paying in any second.
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 believe that at least any payout is due to happen. They can’t leave the machine because as soon as they do it will burst forth and pay out large sums. Maybe it can really work if you have already spent thousands of dollars and have got nothing back. The machine can’t but paying.
Many years ago in the case of the payout players touch the coins to check whether he coins were hot or cold. If the coins were hot they believed that the machine had not paid for a long period of time. 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. One can feel the atmosphere of comfort and trust between the machine and the player.

It seems that every type of activity has its own rules of etiquette, and playing the slots is no exception. 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. Imagine you leave the slot and go to the bar or to the restroom and you want to come back in a few minute and continue playing. How can you let other people know that the slot machine is in play? If you hang a coin cup over the handle of the slot machine it will mean that this slot is in play by you. Placing the coin cup on the seat has the same meaning. In casinos that use a cashless system, a personal item such as a jacket can be placed on the seat instead. In your turn you should respect other players and never sit to a slot that is in play. If you find a card left by the previous player the second etiquette rule has to be applied. It happens very often that a player leaves his card and walks away. If you face a situation like this you have to put the card on the top of the slot machine where it can be easily seen and found. Nowadays most casinos allow smoking while playing. Of course, others will hardly like it, so try to make as few inconveniences as possible. The last etiquette rule is tipping a person, who brings you the winning. In the case of a jackpot tip him with 0,5% of your jackpot.

You can be sure that slot machines are designed to be honest. 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. Modern slot machines differ form the old ones greatly. These machines contain computer chips that are programmed to select numbers randomly. After selecting a number a corresponding symbol appear on the screen. The computer code that generates the random numbers is responsible for whether the machine is “loose” or “tight,” so gaming inspectors look at the machine’s code to make sure that a slot machine doesn’t cheat. There is a legal rate according to which the machine has to pay out. Of course it can pay lower, which happen very seldom.
Because slot machines don’t pay off with every spin, it’s difficult for customers to tell whether a slot machine’s chip has been programmed to pay off less often than is legally required. 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. Some dishonest manufactures use the right to produce machines, but use a different chip, which is programmed to pay less or not so often.
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. 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 you’re playing a machine that is not honest, you can 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.

Meet the man who beat the 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 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.
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. He sold these wands and could 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.
