I did give this game 4 stars b4, Fun and challenging, but issues cauzed by their servers and and their bugs makes you lose boosters, every month i would buy a google play voucher to buy some boosters and stickers and perks and so on for me and my wife, few times maybe like 5 or 6 times when it happens they give your boosters back, but catch is you cannot get the trophies back, i lose because of them they tell you sorry we cannot send you back your stuf you lost coz of us.... No more money from m
