I was supposed to post this yesterday but I fell ill and didn’t access the internet at all (which folks who know me should realize is a really big deal!).
Anyway, I’ll probably edit this post later with PDFs, but for now, just hurrying through the post.
Rules – Follow regular Sudoku rules. Additionally, for every pair of outside clues X and Y, at least one of these cases is true :
1) X is in the Yth position in that direction.
2) Y is in the Xth position in that direction.
