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?
Good guess, it's very much possible infact I think the drafting won't have even accepted the fact that there was a bug if the event hadn't gotten to a great level and number of players who only got fortunate to get paid back because they had reported the issue already.
This kind of incidents has always been on ground but due to the fact that people can not speak out except for reason obvious as this and the number of victims it wouldn't have been possible to get the casino to pay back.
