Nut Sort Puzzle - Color Sort

Tap a tube to lift the top nut, then tap another tube to place it. Move only onto a matching color or into an empty tube to keep stacks organized. Use empty tubes as temporary space and plan several steps ahead to avoid dead ends. Watch the order of colors so you do not bury needed nuts under mismatched ones. Complete a level when every tube contains a single color from bottom to top. Restart the level anytime to try a new approach as layouts and difficulty increase.
