Review for River Spirit Casino Review For Rain Bay Cafe Google User Dec 10 '15 at 23:31 Slot machines pay very low percentage. Second hand smoke is terrible. I told them to quit send any mail and take my information out of their computer. Just put $30.00 in 50 cent machine did not pay anything. The worst percent that I've ever played in Tulsa area. Go to Osage or Cherokee casino in Tulsa area. They will give you more button pushes for your money. The Indian casinos in Oklahoma are unregulated or self regulated. Other states are regulated by state gaming commissions. In my opinion you get more spins where the state regulates the gaming. In Oklahoma there is no authority that makes casinos pay a certain percentage. In others words they don't have to pay anything. Played 8 different $1.00 machines these are the pay percentages 40% 40% 00% 10% 00% 100% 00% 00% Played 9 $2.00 machine pay percentage these are pay percentages 00% 20% 00% 90% 40% 00% 00% 00% 00% If you look most good reviews were months and years ago.
