Dutch Flat Mates (Quads)
(Published on 14. February 2024, 11:30 by Flinty)
Normal Sudoku rules apply.
5's live in Dutch Flats
All 5's in the grid must strictly have EITHER; a '1' directly above it AND/OR a '9' directly below it. It may have both, but it doesn't need both.
Examples provided below on an empty grid.
Quadruples
Digits in a circle must appear in the four surrounding cells.
I've tried making the Quads version of Flat Mates a few times now, and I found it a tough constraint to completely base a puzzle on and not be dull - haha - so fingers crossed this version is enjoyable. Thank you for playing.

Thank you for the kind comments. :)
GoodCity has the reins next week. He has a couple of great options in draft, so it'll be a nice surprise.
