Review for OLG Casino Sault Ste. Marie Review For OLG Casino Sault Ste. Marie Google User Oct 24 '18 at 18:32 I ashamed to say that I have been in a lot of casinos. I can say that this is the best casino in Sault Ste Marie. Lots of slots and multi game machines. No table games are offered before 6 pm. Lots of free parking close by. The staff is generally friendly and helpful. OLG does not publish slot machine return percentages. Neither do the Indian casinos in Michigan so there is no way to compare them. Estimated slot payouts range from 75 to 85 per cent. View full site to comment or like
