About Water Sort
Play Water Sort online for free. Pour colored water between tubes so that every tube ends up holding just one color (or empty). Simple to learn, satisfying to solve, and every puzzle is guaranteed solvable.
How to play Water Sort
- Tap a tube to select it, then tap another tube to pour its top color into it.
- You can only pour onto an empty tube or a tube whose top color matches what you're pouring.
- A tube can only hold a limited number of units, so plan pours carefully.
- The puzzle is solved when every tube holds only one color (or is empty).
Tips & strategy
- Free up an empty tube early — it gives you flexibility to temporarily park a color.
- Look for tubes with just one unit of an odd color on top; clearing those first often unlocks the rest.
- Avoid pouring a color onto a tube where it will just get trapped under a different color again.
- Before pouring, check what's underneath the color you're about to move — if it just buries a segment you'll need again soon, look for another tube instead.
Water Sort FAQ
Is every Water Sort puzzle solvable?
Yes — every puzzle is generated to have a guaranteed solution.
Can I undo a pour?
Yes, use the undo button if a pour doesn't go the way you planned.
How many colors can go in one tube?
That depends on the tube's height, but pours only ever move a matching top segment — so a tube can hold several stacked colors as long as they were poured in a valid order.
