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 slots are casual, there is nothing that can influence the outcome of the game. The slots machine don’t remember wins or loses, they have no memory, so don’t try to overreach 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. 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. 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. If you are more likely to exceed this limit you’d better give up the game. It is not wise to think that you will be a winner all the time. You will lose too. 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. Play the slot machines that your bankroll can afford. Play dollar machines if you don’t have much money. Before leaving the casino don’t forget to cash out the credits. Sounds obvious, but a lot of people forget! Play the slots you know well.

There exist at least two types of slot players.
Persistent player.
The players of this type believe that very soon there will be a period when the machine begins to pay. Any second now the slot machine will roll over and all the coins will be flying out and you will be rich.
The player will play until the machine pays out. He must have found a machine that haven’t paid for a long period of time or he has inserted to many coins and has got nothing. They know the next big win, or any win is due to pay out. The rush is that if they leave after depositing so much money in the machine it will erupt and the payouts will be often and large. 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 where hot then the slot machine had not paid out in a while and to the chaser this was good as the machine was do. But in reality any machine has numerous lights which heat the coins.
The second type of slot players is a chaser.
The player thinks that the machine he is going to play is not a machine that never pays. The player have won and being reinforced by the win gains trust in the slot machine. There is some kind of comfort and trust between the slot machine and the player.
