Anti-8 Killer
I've wanted to set a puzzle with this special "anti-king" type of rule for some time. Turns out the rule is quite powerful, so the resulting grid is rather minimal.
Rules:
- Normal sudoku rules apply.
- Cages show their sums.
- No pair of orthogonally or diagonally adjacent digits must sum to 8.
Puzzle links:
Solution code: row 8

I've seen a few puzzles with a orthogonal sum constraint, but this is the first I've seen where there is a diagonal sum constraint as well. This is a beautiful and well-crafted puzzle that uses these constraints is such a way that five cages in a near-symmetrical design is all you need to have a logical path that is both challenging and fun to find. Thank you for this marvelous creation.
