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 a knight’s move apart cannot contain the same digit.
Palindromes: Digits along a grey line must read the same forwards and backwards.
Positive diagonal: Digits along the positive diagonal cannot repeat.
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: Digits along the positive diagonal, starting at r9c1 and ending at r1c9
