It’s been a while, but I finally managed to sit down and create another Sudoku for my “Colours in the (K)night” series.
Here are the links to the previous parts of the series:
Rules:
Normal Sudoku rules apply. Place the digits 1–9 once in every row, column, and 3×3 box.
Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.
XV: Cells separated by a V sum to 5; cells separated by an X sum to 10. All Vs and Xs are given.
Kropki dots: Cells separated by a black dot must have a 1:2 ratio. Not all possible dots are necessarily given.
Solve online:Sudokupad
Happy solving!
Solution code: Row 8 (9 digits)

That was phenomenal. Took me a bit to get it right but I loved every second.

I just love coloring puzzles.
26:54 => average difficulty (15-30 for me).

There's just not enough colors in this world for these negative constraint puzzles. Other than that, it was great fun.

Lovely coloring exercise. Would have been easier if i remembered the Knights rule but got almost all the way without it. Thanks!

Very nice! I didn’t realise there was a knight’s move constraint until the final stages where I had a deadly pattern, silly me. Thank you
