Pierced Snake
(Published on 25. July 2022, 15:52 by andreasv)
There is one snake (with a head and a tail) that enters each box exactly once. It may not touch itself, not even diagonally.
The number in a circle indicates how many cells the snake occupies in that box.
The first two digits on the arrow, as read from the circle, give a number that indicates the sum of the snake's cells in the circle's box. One circle does not have an arrow. An example can be seen to the right.
Digits along an arrow must sum to the number in the circle.
Normal Sudoku rules apply.
Solution code: Digits from eighth (8:th) row, no commas or spaces.

Very nice and smooth puzzle, with only those givens. Unfortunately, I broke it 2 times because of the circle in box 9, I thought that it had to have a valid arrow attached to it, where the first two digits on it obeyed the snake rule. Maybe you could clarify the rules to say that the circle just counts the number of snake cells in the box.
In any case, thanks for setting this incredible puzzle.
