Sort one color per tube
Tap a tube to lift its top run of balls, then tap another to pour. Finish when every tube holds one color.


Move coloured balls between tubes until every tube holds one matching colour, across 100 levels that ramp from 3 colours up to the full palette. Tap a tube to pick up its top run, tap another to pour — three free hints per puzzle if you get stuck.
