In POP! Christmas by Pady Game Studio you will find many traditional Christmas items flying off from behind the snowy fence to the sky. You are not supposed to tap all of them though! There are two specified targets in each round, chosen from the Christmas icons, which you are supposed to tap so they will not fly off to the sky. And having targets mean that you are not supposed to tap the other Christmas icons beside the targets!
