That's Sum Slithering
(Published on 16. April 2022, 08:56 by andreasv)
- One snake passes through every box exactly once. It can't touch itself, not even diagonally.
- The snake's cells sum to the same sum in every box.
- In each box, the snake must include a digit that represents the length of the snake in that box.
- If a box has given digits, one of them gives the length in that box, and must therefore be part of the snake.
- Normal Sudoku rules apply.

Here is a solve by Mark from Cracking the Cryptic, of a somewhat similar puzzle: Snakes Always Have Chaotic Energy.
Solution code: Digits from row 4, no commas or spaces.

Nice one ! Clever use of the region sum line constraint.
