How to play Color Sort
- Tap a tube to lift the top block of liquid, then tap another tube to pour it.
- You can only pour onto an empty tube or onto a matching colour.
- Pouring moves every matching block on top at once, so stacked colours travel together.
- Finish when every tube holds a single colour or nothing at all.

Tips & strategy
- Empty tubes are the only real resource in the game. Do not fill one unless the pour makes progress.
- Look for a colour that already has three blocks together — completing it frees space immediately.
- Before pouring, check whether the move buries a colour you will need soon.
- If you get stuck, undo repeatedly rather than restarting. The mistake is usually only two or three moves back.
Frequently asked questions
Is every level solvable?
Yes. Levels are built by shuffling an already solved arrangement backwards, so a valid solution always exists.
Is there a move limit?
No. Undo is unlimited and there is no timer, so you can take as long as you need.
What happens as I progress?
Each level adds colours and tubes, up to a maximum of ten colours, and your best level reached is saved.
