How to play Size It Up
Size It Up is a size comparison game. You do not type a number. You resize a silhouette until it looks right next to a reference that is already true to scale.
The board is linear
Twice as wide means twice the real size. The ruler marks 0, a midpoint with a real measurement, and the current view span. It is not a logarithmic slider.
