As with any game of pure chance, there is no real effective strategic system for winning at slots. Never believe if somebody says that he has an incredible winning strategy. The game is random and arbitrary. The slots don’t have memory, that’s why it is not wise to try to outwit them. The strategy can be represented only by a number of tips. You should always be looking for the machines that have the highest payout. Try to find something above 95%. When playing slots you must always know the odds and probabilities of the slot you are playing. There is a payout table for each slot, so make sure you read it before inserting coins. Before you start playing set for yourself a losing limit. Once that limit is reached, go do something else. You will not be a winner every time you play. If you think that the machine you are playing will hardly pay anything out you’d better stop playing it. When things are going your way and you're on a lucky streak, take advantage of it and bet more. Make lower bets if you are slumping. Find a machine that suits your bank-roll. If you have little money you’d better paly dollar machines. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. Sounds obvious, but a lot of people forget! Play the slots you know well.

Here is the list of the most amusing myths concerning 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.
In reality it is not to casino’s advantage to place loose slots at one and the same place, because in this case gamblers would play only these slots. The slots are mixed and nobody can say for sure whether this slot is a loose one or not.
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.
It is not as simple as that. The casino can’t just change the chip of the slot machine. It is illegal and it has to be permitted by the commission.
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.
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.
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.

Slot machines have a vivid and diverse history. They came through a number of changes and improvement. But the objective and the principle of the game always remain the same. Basically, you just put in the coins and wait to find out whether you won or not.
Basically, slot machines are all the same. They only differ in some peculiarities: odds, payouts, payout percentage and symbols. There are so many varying designs around the classic slot machine that everyone could probably find their own ultimate preferred flavour.
Two most distinct types of slot machines are single line and multiline slots. In single line slots, the machine has just one line of reels, usually with 4 or 5 wheels, while in multiline there are a number of reel lines. Multi line slots are a little bit more complicated because winning combinations may play out across a number of lines; when you win, the machine will draw you how the symbols combine together and calculate the win automatically. It can happen that you win nothing during the game or that you win big in a short while. Paylines can be different. They can be vertical, diagonal, zigzags and what not.
Another interesting variation of the slot machine is a jackpot. In jackpot games, the slot machines accumulate a fraction of every wagered bet into a virtual pot. So the jackpot becomes bigger and bigger with every bet. Jackpots can reach several hundreds of thousands dollars. There is only one winning combination that can bring the gambler the jackpot.
Since slot machines appeared they have been played with coins. Online casino slot machines are no exception to that rule, even though bets might differ slightly. Indeed, as well as with all small wager games, there are top bets - they're known as table limits in table games. Slots are the easiest casino games. They don’t require any decision on the player’s part.
Software slot machines (as well as the digital ones) are equipped with a random number generator which is what actually plays the game. This methodic allows very fair and precise balancing without actually hurting neither the players' interests nor the casino revenue.

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 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. 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. That is, inspectors make sure that the machine pays off at the legal rate or better.
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. 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.
There is an example when there was inserted an illegal tip which doesn’t allow royal flushes. Similarly, Universal Distributing Company was caught programming machines to show a “near miss” 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. 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.
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.
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. 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. From that experience, he learned what he needed to know to beat it. 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. With all this money he bought expensive cars, houses and what not.
But as known good things can’t last forever. 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.
