How it works
- Tap a phial to lift its topmost ball, then tap another to pour.
- A pour only lands on a matching colour, or into an empty phial.
- The whole run of matching balls pours at once, as far as it fits.
- Solved when every phial is empty or holds one colour, and is corked.
- Keys: 1–9 select, U undo, Esc cancel.
Every puzzle is built backwards from a solved rack, so it is always
solvable. One puzzle a day, the same for everyone, rolling over at
midnight UTC.
