- Normal sudoku rules apply.
- Primes can’t project on the same digit through rotational symmetry (±90 or 180 degrees).
- One of the prime digits is special, must appear in shaded cells, and can’t ever repeat diagonally.
- In boxes where the special digit appears on the box diagonals, digits in each box row are sequential modulo 9, e.g.,
[1 2 3]or[8 9 1].
This puzzle is another version of my earlier puzzle, All Paths Lead Forward, with a much simplified break in.
Solution code: The 9 digits in the diagonal from bottom left to top right.
