Water Sort Puzzle: Color Sorting Game
Pour the colored liquids from one tube to another until every tube holds just one color. Each level is generated on the spot and is guaranteed to be solvable.
Tap a tube, then another one to pour the liquid.
How to play Water Sort
Tap a tube to pick it up, then tap another to pour. Liquid can only go into an empty tube or onto the same color that’s on top, and only while there’s room: each tube holds 4 units.
When the top layer has several units of the same color, they all pour together (as much as fits). The level is done when every tube is either full of a single color or empty — finished tubes get a cork.
Use the empty tubes wisely: they’re your room to maneuver. Made a mistake? “Undo” takes back as many moves as you want, “Restart” resets the level and “+ Tube” gives you one extra empty tube per level. Every level adds more colors.
Frequently asked questions
Is every Water Sort level solvable?
Yes. Each level is randomly generated and, before it shows up, a solver checks that there’s at least one way to sort all the colors with the empty tubes you have.
What’s the best tip for this color sorting game?
Don’t fill up the empty tubes right away. Before pouring, look for moves that stack a color on top of the same color, and think about which tube you’ll clear first.
Is my progress saved?
Yes. The game remembers which level you’re on in your browser, so you can close the page and pick up where you left off.
