Tube Sort - Ball Sort Puzzle

Tube Sort - Ball Sort Puzzle Sort, clear, relax. Pour the top ball from one tube onto a ball of the same colour, or into an empty tube, and keep going until every tube holds a single colour. Nothing is timed in the Campaign. A pour that does not help is undone for free, and the board is still there when you come back. WHAT YOU GET - Campaign: 1000+ tube boards, played at your own pace - Sprint: three minutes, as many tubes as you can sort - Every level carries an easy, normal or hard label, and the tubes multiply as you climb - Every tube board is checked solvable before it ships - Undo as much as you like, and a hint when no pour looks safe Free to play with ads.
