Measure Up

Differences · 30 levels

A handful of pins must measure every length.

How to play

1. Touch the ruler, slide to a hole and let go to put in a pin. Do the same on a pin to pull it out.
2. Any two pins (the ends count) measure the gap between them. The bar lights each length you can measure.
3. Light every length using only the pins you have. Tap a length to see its arc.

Gaps can be measured between any two pins, not just neighbours. From level 20 the rule flips: use all your pins with no length measured twice. Knots in the wood take no pin.
