About Water Sort
Color Lab: Water Sort is a colour sorting puzzle: pour coloured liquid between cups until every cup holds a single colour. It starts simple and keeps adding twists (faucets, single-colour cups, cups that turn upside down, lids) across 399 levels. Free in your browser, nothing to install.
How to play Water Sort
- Tap a cup, then tap another to pour into it.
- You can pour onto an empty cup or onto the same colour.
- A cup holds four layers, and matching layers on top move together.
- Sort every colour into a cup of its own to finish the level.
- Fewer moves earn more stars: three, two or one.
New mechanics as you go
| From level | Mechanic |
|---|---|

| 181 | Some cups turn upside down after a set number of moves. |
| 301 | Lids close a cup only when it is finished in its colour. |
Controls
- Undo steps back through your pours, up to 120 of them.
- Hint suggests a move; Restart starts the level again.
- New stars earn coins for cup styles and backgrounds.
- Your level, stars and unlocked styles are kept.
Tips
- Keep one cup empty for as long as you can.
- Pour toward the colour that is closest to finished.
- Before each pour, check what it uncovers.
- Use Undo to test an idea: only the final move count matters for stars.
