Thackerville has no floor listed on this site, and Oklahoma has no property pages here either. Start with what the state licenses; the operators further down take US players online, which is the other half of the same question.
We also keep a ranked list of online operators open to US players. State law, not the operator, decides what you can use from Oklahoma — that part is worth reading first.
