Snake in the Mirror

(Eingestellt am 13. Dezember 2023, 18:59 Uhr von ChiefOfHearts)

Normal Sudoko rules apply. Digits cannot repeat along the given diagonal. Additionally, the diagonal is treated as a mirror (I.E. a digit in r1c4 reflects exactly with the digit in r4c1). You must draw a one-cell wide snake of orthogonally connected cells that does not touch itself through all 9 boxes of the grid. One end is the given circle. The snake cannot see itself across the mirror, and digits on the snake do not reflect. All mirrored digits are given. Palindrome: Digits on a gray line must read the same forwards and backwards. Killer Cages: Digits in a killer cage must sum to the value indicated in the top right corner. Cages reflect across the diagonal (I.E. if there was a 20 cage in the bottom left 2x2 of the grid, then there is a 20 cage in the top right 2x2 of the grid). Digits can only repeat in cages without indicated totals. https://f-puzzles.com/?id=yon3qbll

Lösungscode: row 9, column 9

I am having a very hard time parsing the rules here. For example, what does "all mirrored digits are given" mean?

If you take away the mirror constraint, it seems that the puzzle is clearly not uniquely solvable. And I can draw a snake which touches almost every cell that might be mirrored (on one side of the mirror or the other) where the snake and the mirrored snake do not touch except on the mirror diagonal. With the untouched digits mirrored, it still is not uniquely solveable. I'm also not sure what the cage does in boxes 6/9 (it doesn't restrict anything there, and since there's no cage number it doesn't seem that it would restrict anything across the mirror either. Perhaps they need to have the same sum? If so I might put an "X" in the cage or describe this in the rules).
