All surveys that I try to take fail to yield any gems. I run android KitKat 4.4 and have tried with both the included chrome and downloadable Firefox. So far 6-7 attempts and no gems.
I agree, those surveys lead to more surveys, but never gems
They are crap don’t waste your time doing. It is a tap joy thing not a flare games thing, they cant remove them without removing all of the tap joy stuff
