Water Sort Master

About this game

Water Sort Master is a classic liquid-sorting puzzle: each tube holds up to four layers of color, and a pour moves the whole top run of one color when there is room. Levels start at three colors and grow to ten, and every board is verified to be solvable. Collect coins for each clear and spend them on undo and hint refills as you work through all 40 levels.

How to play

1. Tap a tube to pick it up, then tap another tube to pour.
2. A pour moves the top same-color run and needs enough free space — each tube holds 4 layers.
3. A tube is finished when it is empty or filled with one single color.
4. Undo and Hint are limited; coins earned from clears refill them.
5. Finish all 40 levels across five chapters to clear the lab.

Controls Touch or mouse: tap the source tube, then the target tube. Tap the gear for settings, the coin pill for a tip, and the bottom buttons for Undo, Restart, and Hint.
