Heads or Tails?

(Published on 27. July 2022, 15:51 by Xenonetix)

Inspired entirely by RockyRoer's 7x7 version! This one's more of a "Build-Your-Own Irregular Killer" - Good luck!


- Every digit from 1 to 9 appears once in every row, column, and region. 9 regions are to be determined. Every region is a set of 9 orthogonally connected cells.

- Each region is a 9-cell long snake which does not touch itself, including diagonally. These snakes are made up of three parts: 4 cells representing a head, 1 centre cell, and 4 cells making up the tail. Each clue in the grid is part of either a head or tail section and represent the sum of that head or tail section. No section contains more than one clue.

Took me ages to figure out the start but flowed super well afterwards!

Nice logic to build the regions, a bit trickier in the second half. Smooth chaos solve afterwards. Thanks.
