PathPix is an iPhone app where you link pairs of colored numbers by drawing paths and finally revealing a picture. The length of each path must match the numbers on the two endpoints that it connects. You can’t go through the walls that separate some of the squares on the grid. There’s only one way to do it. Link all the endpoints to paint the hidden picture.
