Erica 40 (Dual Modular Edition)
(Eingestellt am 15. März 2026, 15:22 Uhr von SennyK)
Erica keeps on exploring the interactions between German whisper lines and modular 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 modular line.
German whisper: Adjacent digits along a green line have a difference of at least 5.
Modular: Any sequence of 3 adjacent digits along a teal line must contain a complete set of residuals modulo 3, i.e: one from (1,4,7), one from (2,5,8) and one from (3,6,9).
X/V: Digits in cells joined by an X sum to 10. Digits in cells joined by a V sum to 5. Not all Xs and Vs are necessarily given.
Modular Line Explanation:
Basically, if one digit on the line is from one of the groups of residuals modulo 3, then every third digit will also be from the same group; same applies for the remaining groups.

Very interesting combination, the break in is fairly simple once you figure out which line to focus on.

Probably my favorite of the series so far. I do love modular lines. Pass on the compliments to Erica!

looks intractable at first, until you realize that the long lines are VERY constrained, and that GEOMETRY isn't needed. then add a couple of Vs, and the rest of the solve is basic sudoku

To me this was: no clue where to break in. Learn about new rules when breaking in after lots of thinking. The later beeing able to use the aquired knowledge. I love these kind of solves. Brilliant setting thx.
