Dutch Slant Mates
(Published on 10. June 2025, 15:19 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 Slant Mates: Each 5 in the grid either has a 1 DIAGONALLY above or a 9 DIAGONALLY below it. (It may have both, but it does not need both.)
Example: If R2C2 has a 5, there must be a 1 in R1C1 or R1C3 or a 9 in R3C1 or R3C3.
- Killer cages: Digits in a cage must sum to the clue in the top left.
- Renban: Each pink line must contain a set of consecutive non-repeating digits in any order.
Here you can solve the puzzle online:
Solution code: Row 9 from left to right (9 digits in total)

You mention 70 min=3 stars
I assign 4 stars already if it's between 30 and 60 minutes
And yeah, great puzzle.
