Review for Four Queens Hotel and Casino Review For Ioway Casino Google User Mar 17 '18 at 16:06 This is absolutely the worst casino in Oklahoma... cigarette smoke is very bad in casino and restaurant area.. flooring is nasty..not enough staff to handle more than a few people.. people constantly complaining about poor payouts on machines..it's really a horrible place to spend an evening or even 10 minutes in.
