There is no strategy that can really help you to win when playing slots Never believe if somebody says that he has an incredible winning strategy. The slots are casual, there is nothing that can influence the outcome of the game. The machines have no memory, so there is no effective way of outsmarting them. But it is wise to play with useful tips, which can really help you. It doesn’t mean that you will win a lot of money, but you will not lose so much. You should always be looking for the machines that have the highest 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. There is a payout table for each slot, so make sure you read it before inserting coins. Before playing decide how much you can spend this day. Once that limit is reached, go do something else. 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. When things are going your way and you're on a lucky streak, take advantage of it and bet more. When you're slumping, bet less. Find a machine that suits your bank-roll. Play dollar machines if you don’t have much money. It may seem strange but some gamblers forget to do it. Never make high bets if you play slots you have never played before.

Know what you are playing.
Only the correct amount of money should be inserted into a machine. Always cash out your credits before leaving a machine.
Slots shouldn't be a stress for you, just enjoy. Use money management. Increase your bets when you are winning, and decrease your bets when you are losing.

You can be sure that slot machines are designed to be honest. What you can really doubt is the honesty of some manufactures.
When the first slots only appeared cheating was impossible because they worked mechanically, with independent wheels spinning and then stopping randomly. Modern slots are much different. 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. 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. 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. Once inspectors approve a brand of machine, the manufacturers can make changes to individual machines as long as the changes fall within the 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.
In one of the casinos the chip was programmed in such a way that royal flushes would never come out. 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.
