How do I move a core?
Tap a tube, then tap the tube you want to move its top core to, or drag it there. A core can go into an empty tube or onto a core of the same colour. Hold a tube to lift its whole matching group in one move.

I'm stuck. What can I do?
Use Undo to step back, or the hint button to see a good next move. Every level has been checked to be solvable within its move budget.

How do stars work?
Every level has a move budget. Finish with moves to spare to earn more stars. You can replay any finished level to improve your rating.

I deleted the app. Can I get my progress back?
