How would anyone ever know?
If somehow they could manage to get it to cheat only at certain times without having that obvious to inspectors, that would be a hell of a business
I have gone to a local casino and I see a lot of machines where as the player shows his winning to be in the hundreds while me playing the same machine only wining a little. What is the way that they win so much???
I always thought gambeling was a game of chance, until 2 years ago when I started playing slots on a regular basis. I am convinced that the machines are rigged, so that when you are winning someone is contacted and the parameters are changed on the machine while in play!
