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.
This will be a weekly series for as long as my brain allows:
Dutch Flat Mates 1: Classic
Dutch Flat Mates 2: Thermometers (25 Oct)
Lösungscode: Row 4 followed by row 6. (18 digits)

I'm a little surprised at the rating, I quite like this constraint. It's subtle but meaningful, easy to grasp and comes with a lot of implications for other constraints - looking forward to the rest of the series.
