Water Sort
Water Sort (分液排序) is a relaxing colour-sorting puzzle. The rack holds tubes part-filled with layers of coloured water, plus a couple of empty tubes for manoeuvring. Tap a tube to lift its top run of colour, tap another to pour, and work until every tube holds one uniform colour or stands empty.
How to play
- Tap a tube to pick it up — this lifts its top contiguous run of one colour.
- Tap a destination tube to pour: water flows only onto an empty tube or onto the same colour on top.
- Tap the selected tube again to cancel, or use Undo to walk back your last pour.
- Sort every tube so it holds a single uniform colour, or stands completely empty, to clear the level.
Tips
- Keep an empty tube free as workspace — fill it last, not first.
- Pour a colour onto a matching top run to consolidate it before splitting another tube.
- Boxed in? Undo walks back your last pour — every level is always solvable.
