Water Sort guide: empty tubes, partial pours and color planning
Learn legal and partial pours in OnlinePuzzle Water Sort. Use an illustrated capacity example to preserve space and build full single-color tubes.
Read the illustrated guide →Water Sort rules: when can you pour?
Match the top color
Different colors cannot mix
Only the available space fills
What counts as a finished tube?
A single color is not enough: every non-empty tube must contain four layers of the same color. Empty tubes may remain when the level is complete.
40 Water Sort levels, at your own pace
Progress from 3 to 8 colors and 4 to 10 tubes. Early levels have one empty tube; later levels have two. Complete a level to unlock the next, or use Levels to replay an unlocked puzzle. There is no countdown.
Water Sort tips for getting unstuck
Protect your working space
Try to keep an empty tube usable for rearranging colors. Filling it can be useful if the move opens another route.
Look one layer deeper
Before pouring, check which color you will uncover and where that color could go next.
Count the free spaces
A matching destination may accept only part of the top group. Check capacity before committing.
Backtrack with a purpose
If a move closes your options, undo it and try another destination. No legal moves in the current position does not mean the level is impossible.
Water Sort — FAQ
How many levels are there?
There are 40 levels, progressing from 3 to 8 colors and 4 to 10 tubes. Complete a level to unlock the next; you can replay unlocked levels.
Is my progress saved?
Your current puzzle, unlocked levels and complete Undo history are saved in this browser. Language changes keep the same progress. Clearing browser data removes it; progress does not sync between devices.
What does No moves left mean?
No legal pour is available in the current position. Undo one or more moves, or restart. Empty tubes are working space and can remain empty when you win.
Is Water Sort free?
Yes. Play in your browser without an account.
What happens if I get stuck?
Use unlimited Undo or restart the current puzzle.
Is there a time limit?
No. Take your time and plan your next pour.
Why can’t I pour into a tube?
Select a tube containing water. The destination must have free space and be empty or have the same color on top. You cannot pour into the selected tube itself.
Why does only part of a color move?
The game pours the continuous group of matching layers at the top, up to the destination’s remaining capacity. Any extra layers stay in the source.
How do I win a Water Sort level?
Every non-empty tube must be full of one color. A partly filled tube of a single color is not finished. Empty tubes are allowed.
Can I play Water Sort on my phone?
Yes. Tap a source tube, then tap a destination. No dragging is needed. Undo, Restart and the level picker work on mobile too.
