At first game was super and fair, but latelly its just scamming you for items. It stole tons of my achievements, it doesn't give you promissed rewards for events. It steals chips and things you already have. I spent 45 milion of gems to finish the merge event and got back 1 madness chip, one mega chip, one kappa summon out of all promised items. I cracked 2500 summons in one go got tons of streamers, but once i went to use them for upgrade there was only few, also stealing chips on all sides.
