Water Sort Puzzle Guide, Rules, and Tips
Water Sort Puzzle is a calm sorting game: pour colored liquid between test tubes until every tube holds a single color. There is no timer, so it is a good game for relaxing while still giving your planning skills a workout. Switch between a 2D view and a 3D view of the tubes.
How to Play
- Tap a tube to pick it up, then tap another tube to pour into it.
- You can only pour onto the same color, or into an empty tube.
- A tube cannot hold more than its capacity; the pour stops when the target is full.
- The level is complete when each tube contains only one color or is empty.
Strategy and Tips
- Use empty tubes as temporary storage, but try not to fill them with a mix of colors.
- Look for the color that is closest to being complete and finish it first.
- Before each pour, check where the next layer underneath will be able to go.
- When you get stuck, undo a few steps rather than restarting the whole level.
Controls
Click or tap tubes to select and pour. Undo reverses your last pour, the level selector lets you replay levels, and the view toggle switches between 2D and 3D.
Background
Liquid-sorting puzzles became hugely popular on mobile around 2020. They are a modern take on classic sorting and stacking puzzles like the Tower of Hanoi, where the challenge is choosing the right order of moves.
Frequently Asked Questions
Is there a time limit?
No. Water Sort is played at your own pace, which makes it a relaxing puzzle.
What if I get stuck?
Use Undo to step back a few pours, or restart the level to try a different order.
What is the difference between 2D and 3D mode?
The rules are identical. 3D mode shows the tubes in a rotatable 3D scene, while 2D mode is a flat, simple view.
