Dutch Flat Mates (Minmax Quads)
(Published on 14. August 2024, 11:30 by sujoyku)
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Dutch Flat Mates: Each 5 in the grid either has a 1 directly above or a 9 directly below it. (It may have both, but it does not need both.)
- Minmax Quads: Digits in a circle must appear in one of the four surrounding cells and either be the lowest or the highest digit in these four cells. (If there is no conflict with other rules, digits around a quad clue may repeat. In particular, the minimum and maximum may appear more than once.)
Here you can solve the puzzle online:
Solution code: Row 4 from left to right (9 digits in total)

Thank you for your comment, wuc! I am glad that you liked the variant and had a smooth solve. I often also have forgotten about the Dutch Flat Mates constraint when focussing on other parts of the ruleset in some puzzles. :)

It was easy, then hard, but then remembering the Dutch Flat Mates rule, made it easy again.
