Insight Out (Chaos Construction)
(Published on 24. July 2024, 21:57 by sfushidahardy)
This time the arrows see the number of regions, rather than the length of regions. This puzzle should be more difficult than my previous two chaos constructions, but still smooth if you ask the right questions! I hope you enjoy it.
- Chaos construction: every row, column, and orthogonally connected region contains the digits 1~9 exactly once each. The region boundaries must be determined.
- Arrows: the digit in a cell with arrows is the number of distinct regions seen in the direction of one of the arrows, including the cell itself. If there are multiple arrows in a cell, each one must see the same number of regions. To clarify, if the line-of-sight leaves and re-enters the same region, this does not count as a new region.
The following image will hopefully clarify any questions about the ruleset:
Solution code: The digits in row 7, with a forward-slash at region boundaries. For example, 123/45/6789.

The first few digits got in quickly, but you have to be very careful afterwards. I made a silly mistake while running on, broke the puzzle and wasn’t able to detect my fault. So I had to start again. But it was a pleasure to solve this gem. Thank you very much for creating and sharing this masterpiece.

This puzzle isn't harder, but rather significantly easier than the previous ones - slightly below 3 stars for me.

Great use of sudoku in a puzzle where you'd least expect it!
