Frequently Asked Questions about Water Sort Puzzle

How do I play Water Sort Puzzle?
Tap a tube to lift its top colour, then tap another tube to pour it in. You can also press on a tube and let go over another. Liquid only pours onto the same colour or into an empty tube. Fill every tube with a single colour to finish the level. Level 1 walks you through it one pour at a time.
What is the best strategy for Water Sort Puzzle?
Keep an empty tube free for as long as you can, because it is the only place any colour can go. Finish one colour at a time, starting with the one closest to done, and look two or three pours ahead before you commit. A pour moves the whole run of one colour at once, so check how much room the tube you are pouring into has.
Can I undo moves in Water Sort Puzzle?
Yes. Undo is free and has no limit, and Restart puts the level back to how it started. If you are stuck you can also ask for a hint, which shows the next pour of a real solution, or for an extra empty tube.
Is every level solvable?
Yes. Each level is built backwards from a finished board, so an impossible one cannot be made, and a solver checks the levels again. If a board looks stuck, undo a few pours or restart: there is always a way through.
Is there a daily puzzle?
Yes. Once you have solved level 1, a new daily puzzle appears every day, the same board for every player. Solve it on consecutive days to build a run, and pick up a daily gift of prisms for boosters too.
Is Water Sort Puzzle free to play online?
Yes. It is free in your browser with no download or sign-up, and your progress, drops and benches are saved in this browser. The same game is also on Android as Color: Water Sort Puzzle.
Can I play if I am colour-blind?
The twelve colours were chosen to stay distinct with the common kinds of colour blindness. You can also turn on Shapes on colours on the home screen, which draws a mark on each colour.

About Water Sort Puzzle

Water Sort Puzzle is a calm colour-sorting puzzle: pour coloured water between glass tubes until every tube holds a single colour. The rule is simple and the planning is not. Liquid only pours onto its own colour or into an empty tube, and a pour moves the whole run of a colour at once, so every move uses up space you may need later. Levels start with three colours and two empty tubes and climb to twelve colours, with some boards leaving you a single spare tube. Every level is built backwards from a finished board, so none can be impossible. Undo is free and unlimited, restart is always there, and a hint shows the next pour of a real solution. Solve levels to earn drops for new lab benches, come back for the daily puzzle and its run of days, and collect prisms from the daily gift for boosters. It is the same game as the Color: Water Sort Puzzle app on Android, and it plays in any browser on a phone, tablet or computer.

How to Play

  1. Tap a tube to lift its top colour, then tap another tube to pour it in.
  2. Pour only onto the same colour or into an empty tube. The whole matching run moves at once.
  3. Four of one colour seals a tube. Seal every colour to finish the level.
  4. Use Undo freely, keep an empty tube spare, and try the daily puzzle once level 1 is done.
