How to play Color Water Sort
Pour water between tubes until each holds one colour.
Goal
In front of you is a row of test tubes, each holding up to 4 layers of water in mixed-up colours. Pour water back and forth until every tube holds just one colour (4 layers of the same colour) or is empty. Finished tubes get a cork and a little sparkle. When every tube is done you clear the level and move on to a slightly harder one: the first level has only 2 colours, later levels add more, up to 12. Every level is checked in advance to be solvable, so don’t give up!
How pouring works
You can only pour into a tube that is empty, or whose top layer is the same colour as the top layer you are pouring and still has room. A pour moves all the matching layers stacked on top, as many as the other tube can hold. An illegal pour just makes the tube wobble and nothing changes.
Controls
- Mouse / touch: click or tap a tube to lift it, then click another tube to pour. Click the lifted tube again (or an empty spot) to put it down.
- Keyboard: number keys 1–9, 0 pick a tube directly; ← → move the selection frame and Enter or Space lifts/pours; Z or Backspace undoes, T adds an empty tube, R replays the level.
- Buttons below: Undo (3 per level), Add tube (one empty tube per level), Replay the level from the start, sound on/off and colour symbols (every colour gets its own little shape, handy if some colours look alike to you).
You can’t lose: if you get stuck, the game says “No moves left” and suggests undoing, adding a tube or replaying. Progress is saved automatically — close the page, come back later and you continue on the same level. Your best score is the number of levels cleared.
Tips
- Empty tubes are precious: don’t fill one with a stray colour, use it to collect a colour that is nearly finished.
- Before pouring, check which tubes that colour is sitting on top of; pour onto a matching colour rather than into an empty tube.
- Untangle tubes with many different layers first, as they tend to block the other colours.
- Made a slip? Undo right away. Really stuck? An extra empty tube is usually enough to break the deadlock.
