I’m struggling with the cutting.
I have the theme and all the mounts and know the original problem and solution.
Does “all cells are visible” mean all the 169 cells of the original grid or just the 20 that can be moved/repositioned. I see earlier posts that suggest part of the mounts may not be visible for shading.
If the former then the solution still eludes me but if the latter then I can see several ways of achieving a result.
