Erica 19 (German Whisper Yarn Edition)
(Eingestellt am 29. November 2025, 17:15 Uhr von SennyK)
Today we have Erica created for Scojo's prompt with cats and something similar to marty_sear's Rat Run series :-)
I hope you will enjoy and I would be really grateful for all the comments and ratings.
Normal sudoku rules apply.
Leo's Path: Help Leo the puss to nudge his German Whisper Yarn to his friend Kitty. Draw a one-cell wide orthogonally connected path which starts in R9C9 and ends in R5C5. The path can touch itself orthogonally and diagonally, but cannot branch, cross itself, or visit any 3x3 box more than once. Also, it cannot visit any killer cage. Additionally, the path acts as a German whisper line. It must go through every X in the grid, and must visit exactly 1 of 2 cells joined by every V in the grid.
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.
Killer: Digits in a cage may not repeat and sum to the total if given.

The puzzle was very fun, though I do agree with StarGunner.
The ruleset was poorly written and because of that, the interpretation of the rules much more difficult than it needed to be.
This, because specially with the X part, I've seen a rule set where the line could go through both cells of the X line but without it going through the X (e.g. going through R4C5 but instead of going straight to R5C5, going around to R4C4, then R5C4 and then go through R5C5).
However, very fun puzzle and I loved figuring out what the german whisper line was and solving the puzzle.
SK: Thank you for the nice comment! Even you say in your comment that in other puzzles line was taking both X cells "without it going through the X", and in this puzzle it says exactly "line goes through every X", not through every cell connected by the X.

I think the difficulty for me in this one was more in understanding the rules, I will clarify some of the things that tripped me.
When it says the line can touch itself ortogonally or diagonally it means two cells with a green whisper line can be adjacent to each other.
And when it says it has to go through all X dots on the grid it means the whisper line needs to traverse the two cells conforming the X dots.

Not normally a fan of "draw a line" puzzles, but this one was surprisingly approachable and fun. Thank you, as always

I'll give it a spicy 2* but probably not a full 3*
Either way, excellent puzzle. Thanks
