Erica 35 (Fog Edition)
(Published on 25. February 2026, 15:30 by SennyK)
Today, Erica got tricky (my estimation: 3*; testers' estimation: 2*) and hid behind the fog :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Fog: The grid is partially covered in fog. Entering correct digit will clear fog from its cell and all surrounding cells. No guessing is required.
German whisper: Adjacent digits along a green line have a difference of at least 5.
V: Digits in cells joined by a V sum to 5. Not all Vs are given.

Nice fog puzzle. Thx a lot!

Love german whispers and love fog.
Personally I don't agree with this being tricky. There's so many 1* rated puzzles which are harder than this imo. This was pretty smooth sailing with just the GW logic.

Could this be done without observing the tiny slivers of green lines in the corner of cells?
SK: Yes, corners are not needed at all to solve the puzzle.

Not a hard puzzle. Took me a while (40 minutes) but only because I couldn't see the triples and the naked singles toward the end.

I’d say 1.5

To me, a 2* puzzle, but not below. Great interactions, one surely 2* idea along. Great setting thx.

That was a lot of fun! I don't think it's a 3 star difficulty, maybe 1 1/2? I found it pretty straightforward with just some scanning at the end to finish.

Very nice, found this one very easy.

Fun puzzle! Based on my solving time (19min) it is a 2*. I would say it starts as 1.5* and the logic for the last step is close to 3*. Overall a well constructed puzzle with a bit of a tricky endgame! I love this series so far, keep them coming :)
