Colours in the (k)night XIII
(Published on 22. September 2025, 11:02 by Villse)
Next installment in my “Colours in the (k)night” series. I hope you enjoy it.
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.
Palindromes: Digits along a grey line must read the same forwards and backwards.
Kropki dots: Cells separated by a white dot are consecutive; 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 6 (9 digits)

I find these easier when I use the letter tool to pencilmark instead of colours, but even then some of the disambiguation of possible squares was challenging. Always fun to finally figure out what's going on, and be able to slot the numbers in.

Not too hard if you don't make mistakes. If you do, or have fat fingers (like me) it might take you a few tries and some 10 hours (like me). :)
