Modular Stairway

(Eingestellt am 5. Februar 2023, 17:22 Uhr von jcgodart)

Rules:

  • Normal Sudoku rules apply.
  • Global modular : every 2x2 square must contain at least one of each set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}.
  • Anti-Modular lines : every set of three sequential digits along a line CANNOT contain a complete set of residues modulo 3. For instance {153} is not a valid sequence, nor is {729}, but {369} is valid as well as {356} or {127}.
  • Digits joined by a black dot are in the 1:2 ratio. Digits joined by a white dot are consecutive. Not all dots are given.

I don't fully understand the anti Modular lines. Does it mean you can't have the three sets sequential on a line? Or does it mean you can't have for example 3,6 and 9 on the same line?

-----

It means you can't have three digits from the three sets sequential on a line. For instance 153 is not a valid sequence, nor is 729, but 369 is valid as well as 356 or 127.
