The “Colours in the (k)night” series continues. 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 in chess cannot contain the same digit.
XV: Cells separated by a V sum to 5; cells separated by an X sum to 10. Not all Vs and Xs are necessarily given.
Negative diagonal: Digits along the negative diagonal cannot repeat.
Quadruple: Digits in the white circels must appear at least once in the four surrounding cells.
Solve online:Sudokupad
Happy solving!
Solution code: Digits along the negative diagonal, starts at r1c1 and end at r9c9
