Erica 42 (Dual Nabner Edition)
(Eingestellt am 17. März 2026, 13:00 Uhr von SennyK)
Today Erica explores the interactions between German whisper lines and nabner lines, testers' estimated difficulty 2.5* :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Every line is dual German whisper and nabner line.
German whisper: Adjacent digits along a green line have a difference of at least 5.
Nabner: Digits along a golden line form a set of non-repeating non-consecutive digits in any order (i.e., any two digits on a line must differ by at least 2).
Kropki dots: Digits in cells joined by a white dot are consecutive. Digits in cells joined by a black dot are in a 1:2 ratio (i.e., one digit will be double the other). Not all dots are necessarily given.
Nabner Line Explanation:
Basically, no two digits on the line can be consecutive or the same.
If you liked this puzzle, I recommend trying out my other puzzles :-)Lösungscode: Sixth (6th) row of the grid from left to right.

the main difficulty here is FEAR of confronting the nabner lines. but that is PSYCHOLOGICAL, not material.
IN FACT, nabner lines are highly constrained, and THESE lines, even more so.
if you try to avoid the main issue, you cannot solve this puzzle. but if you study the lines, you quickly find that any "middle" cell can only hold 4 digits, and then the "outer" cells are similarly limited.
this populates 32 cells. phistomefel is in play, but not needed.
next, you consider the 3 main kropki sets. all are strongly limited.
the critical cell completing the break-in is r3c8.
the rest is standard reduction and basic sudoku.
all of this is well within the capacity of a beginner.
THEREFORE, the puzzle is level 2.

Another great one in this series, but hard. Took me a long time. I would say hard 2* or maybe 3*.
