Logic Masters Deutschland e.V.

Flinty took a small break this week to sort all the Dutch Flat Mates puzzles coming. This one is the first double variant Dutch Flat Mates.

If you are interested in the serie, you can find the others here.

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.
• 159 : Digits in column 1 indicate the position of 1 in their respective row. Digits in column 5 indicate the position of 5 in their respective row. Digits in column 9 indicate the position of 9 in their respective row.
• Even : Digits in a square are even.

The puzzle is available online via CTC-App
