Modular Ring
(Eingestellt am 7. April 2022, 12:29 Uhr von jcgodart)
Rule set:
Normal sudoku rules apply. Digits joined by a black dot are in the 1:2 ratio. Not all dots are given. Digits joined by an X sum to 10. All Xs are given (negative constraint).
Modular lines: every set of three sequential digits along a line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line if allowed by other rules.
Lösungscode: Row 9

Good puzzle!
I think 3-4 stars is ok. The solving path is quite smooth, but sometimes it took me some time to find the next step.

Nice puzzle! Maybe I missed something, but it felt much harder than 3 stars
