Coloring Clones
(Published on 28. April 2026, 08:10 by RaygunUltra)
Normal sudoku rules apply; i.e. the digits 1 to 9 need to be placed, once each, in every row, column, and 3x3 box.
Digits that are a knight’s move, in chess, away from one another must be different.
The red lines are palindrome lines, i.e. they contain the same digits backwards and forward.
Digits separated by a white dot are consecutive. Digits separated by a black dot have a 2:1 ratio, i.e. one is double the other.
Digits along an arrow sum to the digit in that arrow’s circle.
The pink loopy shapes are clones of one another.
The blue loopy shapes are also clones of one another.
Solution code: Center Box

Forgot the "Knight" rule and still managed to solve. Great puzzle. VERY enjoyable, thank you.

Loved it. The coloring part is a cakewalk compared to the Colors in the (K)night series, but the following logic was tougher. So three stars seems quite adequate.

Wonderful puzzle with some very interesting logic and a tough ending which I enjoyed. I recorded my solve of it on Youtube, I go by PuzzleTank there.
