Erica 37 (German Quadruples Edition)
(Eingestellt am 10. März 2026, 15:00 Uhr von SennyK)
Today we have Erica created for Scojo's prompt with Quadruples and Duality clues :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
German Quadruples: Within the four cells surrounding a circle, orthogonally adjacent digits have a difference of at least 5, and a digit from a circle must appear at least once.
Kropki dots: Digits in cells joined by a white dot are consecutive. Not all dots are necessarily given.
German Quadruples Explanation:
It is just a standard Quadruple (with repeats allowed) with a German whisper line around it.

Love this series. The only reason I tried a 3*. It was very challenging for me, but I got it.

Probably my favorite Erica puzzle yet! I love seeing new constraints like this because I have to figure out new logic instead of going on auto pilot with what I already know. I would greatly enjoy doing another puzzle with this constraint.
