In Bubble Sort, sort colorful balls into matching tubes with smart moves and steady planning to clear each level.
Tap a tube to pick up the top ball, then tap another tube to drop it. Move only one ball at a time, and place it only in an empty tube or on the same color. Use empty tubes as temporary space to group colors. Keep moves tight to finish levels efficiently.
Tip: Create an empty tube early to open space for reshuffling tricky stacks in this puzzle.
