Normal Sudoku rules apply.
Digits on arrows sum to the number in the circle.
There is a loop of orthogonally connected cells that enters and exits all but the middle box exactly once. The loop cannot touch itself, not even diagonally.
Adjacent digits on the loop must have a difference of at least 5 (German whisper).
Arrow circles are on the loop.
Solution code: Digits from middle (5:th) row, no commas or spaces.

I really loved this. Loops that cannot touch diagonally is a criminally underutilised constraint in my opinion. I love colouring the loop green, with inner cells being blue and outer cells being yellow because I get a nice desert oasis artpiece when I finish!

Excellent puzzle. It's fun to change gears between snake/German/arrows/Sudoku. A pleasure to solve!

Beautiful puzzle, and surprisingly, a little easier than it first appears.

I had a lot of fun with this one. The logic follows a nice path arround the grid, each deduction not too hard to spot.
