Vial Sort — colour-sorting puzzle for iPhone

How to play

Tap a vial to pick it up, then tap another vial to pour into it. Only the top run of matching colours moves, and only into a vial that has room and either is empty or has the same colour on top. A level is solved when every vial holds a single colour.

Common questions

Is every level actually solvable?

Yes. Levels are not random deals. Each one is built by starting from a solved board and shuffling backwards through legal moves, so a valid solution is guaranteed to exist before the level ever reaches your screen. The same level number always produces the same board on every device.

I'm stuck — is the level broken?

It isn't, but you may have reached a position from which it can no longer be solved. The app detects this and shows a notice with Undo and Restart. You can undo any number of moves, all the way back to the start of the level.

What does the hint do?

It highlights two vials — the one to pour from and the one to pour into. It never makes the move for you, and there is no limit on how often you can use it.

I can't tell some colours apart

Turn on Patterns in Settings. Each colour then carries its own symbol, so every vial can be identified by shape rather than hue.

Will I lose my progress?

Your game is saved after every move, and again whenever the app goes to the background, so an interrupted game comes back exactly as you left it. Progress is stored only on your device — see the privacy policy.

How do I reset everything?

Settings → Reset progress. This clears your saved game, level progress and statistics permanently.
