JCQ #4: Fierce Creatures (Killer Snake Palindrome Sudoku)
(Published on 16. July 2020, 07:38 by peterchayward)
I met John Cleese a few weeks back, and - knowing he's a big fan of Sudokus - made him a quintet of puzzles inspired by his work. They get progressively harder.
Normal Sudoku rules apply.
The grid is a zoo with 4 cages. The digits in each cage sum to its given number.
In order for visitors to visit the cages, you must draw a 1-cell wide path which starts and ends on spaces on the edge of the zoo.
The path cannot touch itself, even diagonally, and must contain the marked pink space. It may not use cage spaces.
The sequence of digits from the pink space to each end of the path will be the same.
That is, the final path will be a palindrome, with the pink space as the centre.
The sum of the path’s digits from its closest end to the space where it visits a cage must equal the cage’s given number.
The path must visit each cage once, touching only one edge of a single cell.

Solution code: Center column, top to bottom.

Can the path move diagonally or only orthogonally? I can't tell if I'm having trouble with the break-in or trouble with the rules :(

Beautiful puzzle. I like the theme. Unfortunately I forgot that the path had to go to the edge of the zoo. Of course it does, how else will the visitors get in?!

Ich gehöre zwar nicht zu den Sudoku Liebhabern, aber diese Rätselvariante hat mir außerordentlich gut gefallen.
Vielen Dank!
