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 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. Different slots have different payouts. So play slots with the higher payout. Try to find something above 95%. Similar to other casino games, it is crucial to know the odds and probabilities of the machine you're playing. Before you start playing slots get acquainted with the payout schedule. Determine your losing limit for the day. Once that limit is reached, go do something else. It is not wise to think that you will be a winner all the time. You will lose too. The machine will not feel bad if you spend a lot of money and don't get anything back. Try not to spend all of your time on a machine that isn't paying out. Don’t be afraid of making higher bets if you are on a lucky streak with this very machine. 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. It may seem strange but some gamblers forget to do it. Always play what you know.

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. The machine can begin paying in any second.
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 believe that at least any payout is due to happen. 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. Makes sense if you have lost 0. 00 and have yet to win. The machine will pay any way.
Many years ago players have their own way of determining whether the machine has not paid out for a long period of time. They touch the coins to see whether they were cold or hot. 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. The heat of the machines lights, etc would eventually 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. A sense of comfort exists between the slot machine and the player.

It is true that slots are designed to be honest and not to deceive a player. But there are some manufactures that design the slots in such a way that they can deceive players.
When the first slots only appeared cheating was impossible because they worked mechanically, with independent wheels spinning and then stopping randomly. Modern slot machines differ form the old ones greatly. These machines contain computer chips that are programmed to select numbers randomly. After selecting a number a corresponding symbol appear on the 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. The machine has to pay out either to the legal rate or better. Of course the latter happens very seldom.
Because slot machines don’t pay off with every spin, it’s difficult for customers to tell whether a slot machine’s chip has been programmed to pay off less often than is legally required. Inspectors look at brands of machines and their chips before they are installed in casinos, but they can’t inspect each machine. 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 player would never hit a jackpot but keep on playing maximum bets. If you think that you have come across such a machine you have a right to complain. In the case if the complaint the inspectors will visir the casino and check whether the machines have a legal chip. Manufacturers that cheat are fined or they can lose their license.
