Chaos Construction: Snake
Rules:
- Every row, column, and 9-cell region must contain the digits 1 to 9 once each. The 9-cell regions must be determined by the solver.
- A path exists in the grid, starting and ending at the grid boundary and only moving orthogonally, such that each cell is visited exactly once. The 9-cell regions each consist of 9 consecutive cells along the path.
- Clues outside the grid give the number of corners on the path in the indicated row or column. Not all clues are given.
Solution code: Rows 5 and 6

Loved this type of clues, but found it very hard! Fun puzzle in any case!

Took me over 2 hours because of misassumption. Requires a bit of concentration on deducing the regions, the irregular sudoku part was a breeze. Great puzzle nontheless!

I enjoyed this original ruleset a lot. Thanks for making such a fun puzzle.

Great puzzle! Fun and interesting logic in the snake part, and finishing irregular sudoku is fast and easy. Funny enough, I posted a puzzle last year with exactly the same name, although the ruleset and logic is quite different :).

Fun puzzle and quite straightforward. I think it may be clearer to state the 9 consecutive cells portion of the rules as 'The path must enter each 9 cell region exactly once'. Thanks :)
