Mainly, because NO ONE REGULATES the Casinos in the state of Oklahoma because they are their own Greedy Indian Government.
However, they must have lowered 90% of them to pay the lowest they can possibly get away with. They must of had a lot of machines that had pays outs at or above this percentage 8 months ago. Any slot machine set below 91% is not worth playing on.
I am not sure why they are running their Cash Cows away and have to be so greedy. We did try them againg to see how they were. My wife and I used to go to this Casino all the time, but have quit going due to the their extremely tight machines the past 8 months or so.
