Color Bubble Puzzle: Sort Game

Goal: Sort all the colored balls into tubes so that each tube contains balls of a single color. Tap to select the topmost balls of the same color, then tap another tube to move them.

Rules and tips: You can only move balls into a tube that has enough empty spaces, and you can only stack balls on top of the same color or an empty tube. Plan ahead, use empty tubes as temporary storage, and challenge yourself with ever tougher puzzles.
