How to play
- Marbles drop one at a time, in number order. Every marble must land in a cup of its colour.
- A marble rolls to the low end of any lever it meets, and the lever then tips the other way, so the next marble goes the other way.
- Tap a lever to flip it before the run starts. Par is the fewest flips that sort every marble.
- Tap a marble to follow it: you see its route, and the levers as that marble meets them. You can flip levers while following.
- Tap the board during a pour to speed it up. Each tap makes it four times faster.
- Undo takes a flip back, and the flip still counts.
