Meanwhile my personal question is, are slot games really provably fair? If odds can be set to zero, and no one be able to win, is it not possible that some casinos might be using this means or method to cheat slot players off their hard earned money?
It is possible and indeed does happen.
That’s why you have some laid down procedures to proving probable fair games and it varies between games and casinos. However, you can’t be entirely sure all the time. That’s why, you need to be very selective of the casinos you play in as, they could tip the scale in there favor at any given time. It doesn’t matter if they are a physical or online casino.
