There is no strategy that can really help you to win when playing 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 machines have no memory, so there is no effective way of outsmarting them. But there are some tips, which you can use as a basic strategy. Try to play slot 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. Before you start playing slots get acquainted with the payout schedule. Before playing decide how much you can spend this day. Stop playing when you reach this losing limit. It is not wise to think that you will be a winner all the time. You will lose too. 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. Choose a slot according to your bankroll. If you have little money you’d better paly dollar machines. 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.
Persistent player.
This type of slots player is the one that believes the win is right around the corner. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
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 will pay any way.
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.
The chaser.
The player believes the slot machine is not one of those machines that never pay. Players feel more comfortable and confident because they have been reinforced with a win and gain trust in the machine. There is some kind of comfort and trust between the slot machine and the player.
