Colours in the (k)night XVII

(Published on 7. November 2025, 22:16 by Villse)

Next installment in my “Colours in the (k)night” series. I hope you enjoy it :)

Links to the previous parts of the series are given after the rules.

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.

Kropki dots: Cells separated by a black dot must have a 1:2 ratio. Not all dots are necessarily given.

Quadruple sums: Digits surrounding a white circle must sum to the value given in the circle.

Solve online:Sudokupad

Happy solving!

Each new puzzle is more and more surprising! I love how you use the rules to create such fun games!

Very nice as usual! I don't think the 20 in box 6 is necessary to solve

Very enjoyable, the sum dots added an extra layer of math to prevent this being just a pure colouring puzzle which I liked
