Game guide
Water Sort Puzzle deals you a rack of test tubes filled with stacked layers of colored water and asks you to sort them out. Tap one tube to lift it, then tap another to pour its top layer across - but water only moves onto the same color or into an empty tube. Work the colors apart until every tube holds a single shade and the level is complete. The first level walks you through the one rule, then the layouts grow with a limited number of moves per stage.
Actual gameplay


Objective and input
Each level deals several tubes holding stacked colored layers plus at least one empty tube. Tap a tube to pick it up, then tap a target tube to pour: the top run of one color flows across, and one pour can carry several matching layers. Water pours only onto the same color or into an empty tube, and each tube holds four layers, so a full tube accepts nothing more; an off-color target simply refuses the pour. Fill every tube with one color to finish - a Completed panel appears, and Next deals the next layout. A counter caps the moves each stage allows, so every pour should free a color rather than just shuffle it.
The site framework maps mouse input to the same actions: click a tube to pick it up, then click another tube to pour into it.
Tap a tube to lift it and select the water on top.
Tap another tube to pour into it: the top color moves across when it matches the target's top layer, or when the target is empty.
Tap the curved arrow to undo a pour, the speaker to toggle sound, or the circular arrow on later levels to restart the stage.
What stands out
Water pours only onto the same color or into an empty tube - the first level teaches it with a guiding hand and on-screen text.
Several matching layers move in a single pour, so batching colors saves taps from the level's move budget.
Each stage reshuffles the tubes - level two already adds a sixth - and progress is saved for your next visit.
A counter caps the pours each level allows, so move order matters as much as the rule.
Useful guidance
Use empty tubes as parking space: set a blocking color aside, finish another tube, then come back for it.
Finish a tube as soon as you can - a completed tube accepts nothing more and is out of the puzzle.
Before pouring, check what the move uncovers: freeing the layer below beats tidying the top.
