The Mystery of Slot Machine Strategies

I have read a lot of information about Slot Machines, for both land-based and on-line casinos, and I am, quite frankly, curious to test out the effectiveness of the tips and strategies that are available on the internet.  I understand that slot machines use Random Number Generators (RNG's) to continuously cycle through numbers used to generate a play's result and that this is occurring even when the machine is not being played.  So how can a strategy tell you when to play a machine and how much to play?  The gambling strategies that I have seen, including the ones available on the Winner's Gambling Systems website, have been developed by people who have spent years studying and developing their systems.  They teach players how they work and how to "read" the slot machines to determine which ones to play.  They also teach when to change games and when to give up on non-winning machines as well as the best games to play and the best times to play them.  Many people love slot machines, as I do, but have lost more than they have won over time.  A good slot machine strategy can prove to be a good investment.  They all provide a Money Back Guarantee if you are not satisfied with their product, so you really can't go wrong.  I am planning to purchase one of these shortly and will post my findings as soon as I have completed a test of the chosen strategy.  (This may not be for a little while yet as I lost my job in January of this year and have not been able to secure a new one yet.)  So please stop by again some time and check out the results!
