Whilst random number generators are random due to their design, it has been discovered that some of the older styled ones are designed in such a way that it is possible to reverse engineer them and players with mathematical skills would be able to determine just where in the cycle of random numbers a random number generator is. I have however come across one way that a cell phone can be used as a way to defraud slot machines and having checked into the way that is possible I do have to say it is an amazing story, and even to this day some slot machines are still vulnerable to being ripped off with the use of a cell phone, and below you will discover just how that fraud has been and still is being committed.
