Color Tubes is a calm logic puzzle about sorting colored balls into tubes. Pick a tube, move the top group of matching balls, and collect each color in its own tube. The game includes 30 levels, from simple warm-ups to denser layouts where empty tubes, move order, and careful planning matter. Finish with fewer moves, hints, and undos to earn more stars.
Tap a tube with balls, then tap a destination tube. You can move only the top group of balls with the same color. A move is allowed when the destination tube is empty or has the same color on top. The goal is to collect every color in a separate tube. Use empty tubes, plan the order of moves, and try to meet the level target. Undo returns the last move, and Hint shows a possible next move. Fewer moves, undos, and hints give you more stars.
