Potion Sort: a water sort puzzle with 240 levels
Potion Sort is our take on the water sort puzzle: a shelf of glass flasks, each filled with mixed layers of glowing potion. Your job is to pour them around until every flask holds one color and gets its cork. It starts with three or four colors and slowly grows into a real planning challenge.

How to play
- Tap a flask to lift it.
- Tap a second flask to pour: the top color moves onto the same color or into an empty flask, as much as fits.
- Fill a flask with four layers of one color and it is corked and set aside.
- Cork every color to clear the level, then aim for three stars by using fewer moves.
What it exercises
A calm water sort game that still asks you to think a few pours ahead.
Planning
Later shelves have few free spaces, so you work out an order of pours before you commit to the first one.
Working memory
From level 51 some layers are cloudy and only show their color when they reach the top, so you keep track of what you have already seen.
Patience
Slowing down to look at the whole shelf before pouring is part of the fun, and a good way to keep your mind active.
Tips
- Keep one empty flask free for as long as you can; losing it early is the usual way to get stuck.
- Pour onto flasks whose top color matches a long run underneath; one pour can then move two or three layers at once.
- Every potion carries its own rune, so if two colors look alike, sort by shape.
- Each level gives you 5 undos and one extra empty flask. The flask is a safety net, but using it caps that level at two stars.
- On a keyboard, number keys pick flasks and U takes back the last pour.
Frequently asked questions
Can I play this water sort puzzle online for free?
Yes. Potion Sort runs in your browser on a phone, tablet or computer. It is free, with no ads and no download.
What are the water sort puzzle rules?
You may only pour onto a matching color or into an empty flask, and only as much as the flask can hold. A standard flask holds four layers. The level is solved when every color sits in its own corked flask.
How do you win a water sort puzzle when you are stuck?
Undo a few pours and look for the move that freed up the most space. If that fails, add the extra empty flask or restart the level with a new plan.
Is there a water sort puzzle solver for these levels?
There is no built-in solver, but our own checker solved every one of the 240 levels before release, so each shelf has a solution.
Does this color sort puzzle get harder?
Yes. Levels 11 to 50 use five to seven colors. Hidden layers arrive at level 51, empty flasks become scarcer from level 71, and from level 151 you meet small vials that hold only two or three layers and sealed flasks that open once their rune color is corked. Every level ending in 5 from 15 on is a gentler breather.
Is it a liquid sort puzzle without ads?
It is. Nothing pops up between levels of this sorting game.
