Nabnerfel

(Published on 23. April 2026, 05:59 by antiknight)

I wanted to create a puzzle with this theme since it’s been gaining popularity again with the Nabner constraint. I hope you enjoy it, and feel free to leave a comment if you did or if you enjoyed the break-in.

Rules:
  • Sudoku: Normal Sudoku rules apply.
  • Arrows: The digits along each arrow must sum to the digit in the circled cell.
  • Nabner: Digits on each golden line are non-consecutive.
  • Kropki Pairs: A white dot between two cells indicates that the digits are consecutive. Not all such dots are shown.

This is very good with some a-ha moments that seem to fall out of the sky. It boggles my mind how this can be so forced.

something wrong with the german statement of the arrow rule (sum of S = {A,B,C,...})

also, this is NOT level 2.

"fairly easy for experts (and it IS an "experts only" puzzle *) does NOT mean the same as "fairly easy"

(*) required knowledge:
1) basic phistomefel
2) good understanding of nabner logic
3) recognition of h/l requirements of 3-cell arrows

and that's just to get started.

Really nice, with just the subtlest symmetry break.
