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 game is random and arbitrary. The slots don’t have memory, that’s why it is not wise to try to outwit 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. Play slots with the payout 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. 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. When playing remember that you can win as well as lose. 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. Find a machine that suits your bank-roll. Play dollar machines if you don’t have much money. Don't forget to cash out the credits you've accumulated. It may seem strange but some gamblers forget to do it. Play the slots you know well.

To know what you are playing is necessary for you.
Always make sure that you insert the correct amount of coins into a machine. Cash your credits and only the leave the machine.
While playing just have a good time. Use money management. Increase your bets when you are winning, and decrease your bets when you are losing.

It is true that slots are designed to be honest and not to deceive a player. 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. The numbers the computer selects correspond to the symbols that appear on the slot machine’s 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. 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. 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. Using their right to produce slot machines they insert different chips, which makes the machine pay less.
For example, the Nevada Gaming Commission caught American Coin using chips that did not allow poker royal flushes. Similarly, Universal Distributing Company was caught programming machines to show a “near miss” 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. 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.
