Ball Sort
Move stacked balls between tubes until every tube holds a single colour.
Rules
- Click a tube to pick up its top ball, then click another tube to drop it.
- A ball can only land on an empty tube or on top of a ball of the same colour.
- You win when every tube is either empty or filled with a single colour.
Controls
- Click a tube to lift the top ball (or the whole same-coloured run on top). Click another tube to drop it there.
- On mobile, tap a tube to pick up its top run, then tap another tube to drop it.
Tips & Tricks
- Combine tubes that share the same top colour to free up a slot.
- Before you cover a ball, check what is sitting underneath it. Burying the wrong colour can lock the puzzle.
- Empty tubes are precious.
