Colour Sort

Pour balls between tubes until every tube holds one colour. Two spare tubes are your workbench.

Colour Sort runs completely inside your browser — nothing to install, no account, no download. The board is drawn on a 960×540 canvas that letterboxes itself to any screen, so it plays the same on a laptop, a Chromebook or a phone in landscape.

How this version plays

The whole run is built around one idea: Click a tube to lift its top run / Click another tube to pour. We tuned the speed curve so the first thirty seconds feel gentle, and by the second minute you are genuinely busy.

Scoring

A finished level pays up to 700 points, reduced by 8 per move — a 20-move solution earns about 540. Levels add one more colour each round up to eight.

Why we kept it small

The undo-free design is deliberate: with two empty tubes any shuffle is recoverable, so you learn to plan two pours ahead instead of relying on a safety net.
