Tap a tube to pick it up, then tap another to pour · Symbols adds a shape to each colour

Level: 1
Colours: 3
Pours: 0

The prompt

Make a water sort puzzle in one HTML file. Tubes hold 4 units. Shuffle the colours into tubes plus two empty ones, and run a depth-first solver to make sure each level can actually be solved before showing it. Pour moves the whole top run of one colour onto a matching colour or an empty tube. Undo, restart, endless levels that add colours, and an option to show a shape on each colour for colour-blind players.

Claude wrote this game from a short brief like this one. It was then played, tested on phones and tuned before it went up here.

How to play

Tap a tube, then tap where to pour. You can only pour onto the same colour or into an empty tube.
All the matching water on top pours at once, as much as fits.
Finish when each tube holds a single colour. Every level is checked to be solvable.
