About Water Sort
Water Sort is a soothing colour-sorting puzzle. You start with test tubes of mixed coloured liquid and two empty tubes. Pour from one tube into another — but liquid only flows onto an empty tube or a matching colour, and the whole run of the top colour moves at once. Work the colours apart until every tube holds a single colour. Every puzzle is generated and checked to be solvable before you see it, so there are no dead ends by design. No signup, no download.
Frequently asked questions
Tap a tube to pick up its top colour, then tap another tube to pour. Liquid only flows onto an empty tube or onto the same colour, and the whole run of the top colour moves at once. Sort every tube down to a single colour to win.
Yes. Each puzzle is generated and then verified by a built-in solver before it is shown, so every layout you play has a guaranteed solution and no dead-ended start.
You can pour onto an empty tube or onto a tube whose top colour matches what you are pouring, as long as there is room. The entire top run of that colour moves together, up to the space available.
Yes. Use Undo to step back a pour, or Reset puzzle to return the same layout to its starting state and try a different approach.
Difficulty sets how many colours — and therefore how many tubes — you juggle: easy uses three colours, normal five and hard six, each with two spare empty tubes.
