Mod 9 makes it solvable
(Eingestellt am 25. Mai 2021, 05:39 Uhr von rmahus)
Normal Sudoku rules apply.
Additions and multiplications are Mod 9 and 9=0 is written down as 9.
Digits in two cells separated by an X sum to 10.
Digits in two cells separated by a V sum to 5 Mod 9.
White dots join cells with consecutive digits. 1 and 9 are consecutive.
A cell joined by a black dot is twice the other Mod 9. For example mod9 (2 * 8) = mod9 (16) = 7. 7 can join 8

Are 9 and 1 consecutive digits? Mod 9 they are.

I really liked this puzzle. First figuring out all the new kropki possibilities, and then eliminating them using the other clues.
