greatest puzzle ive played on ng
the following is a solution of #12 for the reviewer below me dont read further if you want to solve it yourself:
the set in the top right corner contains all numbers from 1-15 except 5, you just have to place the conductors properly (correct positioning is figured out by controlling which terminals connected light the bulb) so the display on the right shows the number 5, and work yourself up from the bottom ftw
