Chaos Construction: Gaps
(Published on 29. March 2022, 07:47 by KNT)
Rules
Normal Chaos Construction rules apply. That is, divide the grid into 9 orthogonally connected groups of 9 cells.
Both cells on each arrow are in the same region. However if a digit N is in the bulb of the arrow, then the N cells in front of the tip of the arrow are not in the same region as the arrow, and the N+1th cell is in the same region as the arrow. Example: If R2C2 was a 3, then R2C2, R2C3, and R2C7 are in the same region, and that region does not include R2C4, R2C5, and R2C6.
Digits separated by a white dot are consecutive, and in the same region.

As far as chaos constructions go, this should be fairly approachable. I hope you enjoy it!

That was fun and not very hard, although the irregular sudoku took longer than the region building for me

An easy 4, or a hard 3, let's see about the next one :)

This is indeed quite approachable. And fun, too. :)

Interesting puzzle with a nice constraint once you understand it properly. I first tried to build the regions considering that the N+1th cell could be outside the grid, therefore possibly not in the same region as the arrow. I quickly realized it was just impossible and you had to have a N+1th cell IN the grid ! Then it became quite easier to solve. Good one !

Good puzzle! I found the construction part quite straightforward, but it still has some really nice logic in it.
