Knights Journey
(Published on 16. January 2026, 15:14 by TalkingFredish)
Rules:
You are a knight sent on a quest to find the missing princess!
Normal Sudoku rules apply.
FOREST OF FOG
- One box is covered by fog. Placing correct digits might clear some of the fog.
KNIGHT'S PATH
- The knight starts by leaving the castle (r2c2 to r3c2), and ends on the princess, who is somewhere in the fog.
- He can only move orthogonally, and adjacent digits on his path differ by at least 5.
- The path can't cross itself or water without using a bridge.
- The first cell in a 3x3 box used by the path must be equal to the number of cells it visit in that box.
- The path never returns to the same 3x3 box twice (and might not visit every box).
FARMS
- Farm fields sum to the total in the corner.
- One of the farm cell shows its digit(/given).
WATER
- Open water cells (those without a bridge or boat) must have at least one of every digit.
(Everything else is cosmetic.)
Solution code: Row 1 left to right, followed by the princesses whereabouts. Divided with a "-"
Example: "111111111-R1C1"

A very nice puzzle with interesting rules and the beautiful picture.Also I like the smooth logical chains from beginning to end

I think I must have missed something with the 3-star difficulty and number of solves. It took me a quite long logic chain just to rule out one of the "early" possible paths. After that, it started to come together smoothly, but boy was that portion grueling.
That said, some quite interesting logic about how the line had to behave. The German Whisper + First-Cell rule had some fun consequences.
Also like another poster I clicked thinking this would be a Knight's Move puzzle. Wasn't disappointed overall, but the naming does defy convention and had me double-checking to make sure it wasn't a rule here.

Very nice graphic. Later half of the solve is definitely closer to 4*. Deserves a higher rating!

Very Cool Puzzle!
The rule regarding the first visited cell in each region leads to some nice logic.

Some of the cosmetics made tracking my paths and corner marks slightly difficult, but this was a very interesting solve. Once I got near the end, reconciling the potential paths for each box required brute force to deduce the only possible path. Perhaps there was a more logical approach I missed? I had expected a knights constraint, given the name. Thank you for the puzzle!
