Get Up on the Hydra's Back! (Chaos Construction)
(Published on 20. August 2022, 10:38 by tesseralis)
This puzzle introduces a new ruleset I call "Anatomino" that I think has some potential. Please do try it out and let me know what you think!
Place the digits 1-9 in each row, column, and orthogonally connected region. The regions must be determined.
A cell with a number N in the top-left corner counts the number of cells in its region that have N orthogonal neighbors. (For instance, any snake has two 1-neighbor cells and seven 2-neighbor cells.) A question mark indicates an unknown value of N. Examples of valid clues and regions are shown below, with cells of different neighbor counts highlighted.
Solve on:
Example regions
Solution code: Column 1 followed by Column 9

Excellent CC, with a really interesting study of irregular geometry. Thanks :)

Cool break in, and unique logic

Nice puzzle, broke it at the end, but hopefully fixed without many changes

had to put the puzzle aside for a while, wondering how to start. Today the obvious break-in hit me. After that the puzzle developed nicely into a great CC. thanks.

Great use of geometric deductions, thanks! I liked how the regions unfold.

Very rare use of a global geometric constraint in a CC puzzle. Enjoyed it, very different!

Interesting new rule and a very nice setting. More approachable than it looks at first glance. Thank you very much!

Interesting ruleset, though I found it fairly tricky to keep track of. It feels like there's some scope for interesting puzzles using a negative constraint on this ruleset

yeah! I feel like it'll combine well with other polyomino puzzles too. It is tricky, but there are some strategies like coloring and keeping track of counts that help with that. ~tess
