Chaos Deconstruction: Double Snake
(Published on 25. July 2022, 03:25 by KNT)
Two snakes, we call them snake A and snake B, are to be drawn in the grid. A snake is a one cell wide path that travels orthogonally from cell center to cell center. The snakes must not touch themselves anywhere - orthogonally or diagonally, but they may touch or even intersect each other. However, no two adjacent cells may belong to both snakes. The dashed circle indicates an end of a snake.
A number in a yellow cell indicates how many of the cells in the surrounding 3x3 area belong to snake A. A number in a blue cell indicates how many of the cells in the surrounding 3x3 area belong to snake B. A green cell behaves as both a yellow cell and a blue cell. All colored cells are nonempty.
Every region is entirely part of snake A, or entirely part of snake B. Cells where the snakes intersect belong to two regions simultaneously.

Solution code: Row 9 followed by Column 8, ignoring empty cells.

Definitely the most cursed of the 3. Bit tricky in places, with some weird and interesting logic throughout. Fun puzzle.

Thanks KNT, that was both really weird and cool. Always nice to wrap your head around something quite different!

Don't be scared, people! This in only 4/5 difficulty - AKA a paper tiger. :D

Amazing puzzle! Particularly enjoyed the multitude of different types of logic that had to/could be applied to solve it. Thanks!

Very tricky and at least as beautiful.

Ruleset sounds pretty insane at first but the solve went quite smoothly for me. Lots of fun, thanks for setting!

Wow, that was a fast solve. Thanks for solving and I'm glad you enjoyed it! It certainly was a very difficult set for me, I've come back to this idea on and off for close to a month now, and I'm very glad I was finally able to make it work in a smooth way.

Mind-boggling, a real test! Very satisfying to solve. Amazing feat to construct this, oh evil setter, though I fear you suffered the worst DOS out of this entire escapade.

True, I definitely did DOS myself while setting this, haha
