Sorry didn't realize they weren't still a sponsor. I'm not sure about the docs but they definitely removed the wording about 1 spin every $10 spent from the app. I don't it hard to believe that's a mistake. 

Not sure why they're doing this; feels like the only reason anybody would still be using them at this point is momentum. Not sure how they will sustain this because I can't be the only one thinking of not using them any more.
