I had to update my review. Well now that I'm on level 560. The ads keep freezing up my tablet. And I am sick of it. I've held my tongue for 2 weeks. I've uploaded updates and clean my cache every day and still my tablet freezes. I've collected over 80K in gold coins. Still have no clue as to what there for. I have over 40 of every booster available. I am willing to uninstall all of it, if this FREEZEING continues. PLEASE ADVISE ASAP, THANK YOU.
