There is hardly any strategy that can be applied to slots. Never believe if somebody says that he has an incredible winning strategy. The outcome of slots is accidental. 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%. Like other casino games it is very important to know the odds and probabilities of the game you are playing, the same thing with slots. Make sure you know the payout schedule before you start pumping in your virtual coins. Before playing decide how much you can spend this day. If you are more likely to exceed this limit you’d better give up the game. 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. 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. When you're slumping, bet less. Choose a slot according to your bankroll. Play dollar machines if you don’t have much money. Cash out the credits you’ve won before leaving the slot machine you’ve been playing. Sounds obvious, but a lot of people forget! Always play what you know.

I tis important to now what you are playing.
Always make sure that you insert the correct amount of coins into a machine. Always cash out your credits before leaving a machine.
Just have fun. Slots should be fun, not stressful. You can increase your bets only when you are winning, and decrease your bets when you are losing.

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.
In the old days, slot machines worked mechanically, with independent wheels spinning until they each 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 numbers the computer selects correspond to the symbols that appear on the slot machine’s screen. 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. 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. 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. 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. One the one hand the machine would never have a jackpot and the player would keep on playing. 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.
