Also you might have to reconsider on playing 3-6 star levels and play 1-2 star levels if your new to this game especially top to bottom, also the position of levels are based how close they are to their lower stars or higher stars, only if it’s in middle, it’s the perfect level for that star and the more stars you progress, the harder your levels gets, especially by calculation of stars, again, your welcome
