Two sides of a ratio
(Published on 19. October 2026, 11:53 by Ollos)
Normal sudoku rules apply.
Place the digits 1-9 in every row, column and 3x3 box.
Ratio kropki dots:
Digits connected by a black dot are of 1:2 ratio with one another.
Ikpork dots:
Digits connected by a pink ikpork dot must individually be able to appear on either side of a valid ratio kropki dot (for a 9x9), but the two digits must not be in a 1:2 ratio.
(Example: with "1-2-4-8-3-6", 2 cannot connect to 1 and 4 due to being in 1:2 ratio with both)
Consecutive kropki dots:
Digits connected by a white dot are consecutive.
Solution code: Row 9

@Rollo - I think it means that digits connected by a pink dot can be any digit other than 579, but they can't be double the other - for example, 4 and 6 could be connected by a pink dot but 4 and 8 couldn't. That's how I interpret it anyway, not tried the puzzle yet.

Wonderful rule, great puzzle flow!
Indeed: pink dots connect digits from 123468 that are not in a 1:2 ratio.

Ich verstehe die Regel und auch das Beispiel nicht. Zwischen welchen Ziffern im Beispiel soll ein rosa Punkt sein, und wieso kann 4 neben 2 und 8 stehen?
