Erica 8
(Eingestellt am 12. November 2025, 17:15 Uhr von SennyK)
Erica continually keeps becoming increasingly challenging, this time new constraint was introduced! However, do not fret, as the previous episodes should have prepared you sufficiently to face her.
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
German whisper: Neighbouring/adjacent digits along a green line have a difference of at least 5.
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 given.
Entropic: Any sequence of 3 adjacent digits along a peach line must have a low digit (123), a medium digit (456) and a high digit (789).
Entropic Line Explanation:
Basically, if one digit on the line is low, then every third digit will also be low; same applies for the remaining groups.
The Erica Series:
Episodes: 1, 2, 3, 4, 5, 6, 7

Always happy to solve a german whisper nicely put puzzle, thank you for this serie !
I actually don't agree with the comments, the 2* seems appropriate, there were no special technique needed or any sudoku background (expect for marking).
Coming from a beginner myself who have done some 3* past few days that took me double or triple the time

although all the world class solvers are here, the vast majority of sudoku fans are not that.
beginners will try this puzzle, and find it completely intractable.
save them the trouble by stating the difficulty correctly - level 3 (or higher)
SK: Thank you for solving! I do not agree, as it can be easly solved with only coloring and basic GW/sudoku principles. Also, as you can see the difficulty rating is fixed on 2* and it was decided by 50 solvers together.

Nice puzzle but very hard (4 stars?) with some chaining in the middle. Took me 74 minutes and I have the screenshot and blisters to prove it. I suspect I missed something obvious somewhere!
SK: Thank you for solving! I must worn you that if this was 4 stars for you, then Erica 9 showing up tomorrow would be 7 stars at least :D

Extremely fun puzzle, I loved the interaction between the whisper and entropic lines. Gotta check out the rest of the Erica series now!

Nice puzzle. The addition of the entropic lines adds a slight ambiguity interaction with whispers the solver needs to find. Enjoyed this a lot.
