Foggy Whisper Loop
(Published on 9. June 2023, 21:08 by yttrio)
Rules:
Normal Sudoku rules apply.
Digits in a cage must not repeat and must sum to the number in the top left corner of the cage.
Digits separated by a white dot are consecutive. Not all dots are given.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
- The loop must enter every cell of every cage.
- The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).
Additionally, the grid is partially covered in fog. Placing correct digits will clear the fog from surrounding cells, possibly revealing more clues.
Solution code: Row 1 followed by column 5 (18 digits no spaces)

Fantastic puzzle! That was tricky break in! 2* difficulty once you're past the 3* break in. Flows wonderfully after the break in.

Awesome. Bit harder than most 3 star to me. Thx.

Thanks for this puzzle. I had seen it posted on YT but had to give it a try myself before watching that. Often a 3 star is a bit to much for me but I'm glad a tried. Loved the break in and even for me it flowed very nicely.

Brilliant puzzle, love it! Hard break-in, then it is quite approachable.

A really nice puzzle, thank you! I loved the break in! Sadly I made an error mid-way through on the loop and got stumped for an hour; wasn't until I finally broke and watched the CtC video did I realize my error and could finish the rest.

I'm loving this. My favourite constraints combined in one puzzle! Thank you so much for making it, yttrio!

Very good puzzle. Difficult break through though.

Enjoyed this so much. Took me a while but I got there. The break in was tricky and there were plenty of other places that were tough

a lot easier than it looks, but not a beginner puzzle.
There is one trick at the start (a simple principle) that only a whisper loop expert will know, but the rest is straightforward.

This is a beautiful puzzle, well done, but unless you have experience with whisper loops I think that break-in is going to be very elusive. Definitely tougher than three stars for me.

Loved it! I’ve seen a similar break-in before, so that helped. But the rest of the puzzle kept requiring me to be on my toes. Thanks so much!

I haven't been among the huge fans of foggy puzzles, but I nevertheless appreciated a few of them, and this one was of the very best kind. Thank you and bravo!
