The 6×6 Points Connection Problem
The 6×6 Points Connection Problem
Join all 36 grid points with a polyline, where each segment of the polyline has to have a length different from all other segments.
The segment lengths are displayed at the bottom (the height displayed is a third of their original length).
If you use the same length twice, the last placed segment will turn red and you have to hit the "delete last stored" button or the "reset" button.
