Dutch Flat Mates (Full Rank)
(Published on 2. October 2024, 11:30 by goodcity)
If you are interested in the Dutch Flat Mates serie created by Flinty, you can find the others here.
Normal sudoku rules apply.
- Dutch Flats : All 5's in the grid must have a 1 directly above it or a 9 directly below it. It may have both, but it doesn't need both.
- Full Rank : A total of 36 nine-digit numbers can be read in the rows and columns, each viewed from both directions. If these are sorted in ascending order, the numbers outside the grid indicate the position in this sorting at which the nine-digit number seen from the respective direction is located.
The puzzle is available online via CTC-App
Solution code: Row 6

Nice puzzle. Had to restart two times as I made the same error twice. I love this series because of the strange variants you don't see every day.

51 Wednesday's in a row, crazy stuff! 100% wouldn't have happened without you. Thank you again my friend. Here's to many more flat mates in the future.
