The Great Wall
(Published on 9. September 2022, 07:42 by tesseralis)
Normal sudoku rules apply.
Draw a one cell-wide snake (the Great Wall) that passes through each box exactly once and cannot touch itself orthogonally. Digits on the Wall must be greater than orthogonally connected digits not on the wall. Each given digit indicates the number of cells in that digit's box that are on the Wall.
There are nine "guard towers" along the Wall, one in each row, column, and box. Each guard tower contains a different digit from 1-9, and the Wall must visit each of the guard towers in ascending order.
Solution code: Rows 1 and 8

Wonderful ! The fortress logic at the end stalled me a bit, but finding out the missing piece that unlocked everything was so satisfying. Thanks :)

Break in was hard. Rest of puzzle was bumpy for me but logical and I didn't quite come up on any serious speed bumps along the way.

Brilliant idea, great geometry logic AND great fortress logic afterwards. Possibly on the low end of 4/5 difficulty.
