Some liquids do not mix, and when you do put them together, they form separate layers. That fact is the starting point of WaterSortPuzzle. In this minimalist brain teaser you are confronted in each level with a number of test tubes containing different layers of colored liquid. It is up to you to separate all the colors using a few empty tubes. That sounds easier than it is, because you may only transfer liquids to an empty tube or to a tube whose top layer contains the same color liquid. Hours of puzzle fun.
