What is Aqua Sort?
Aqua Sort is a water sort puzzle game where you lift a test tube, watch it swing over another one and tip its colored liquid in, until each tube holds a single shade. The 36 levels run through four lab chapters, from Apprentice Lab with 3 colors to Grandmaster Sanctum with 8, and every board gives you exactly two empty tubes to work with. Par on each level is the shortest possible solution, checked by an A* search, so hitting it means you found a flawless route. Truly stuck? A one-time +1 Tube rescue is there, at the price of your third star.
