Logic Masters Deutschland e.V.

Rules:

Normal Sudoku rules apply.

All lines in the puzzle are either German Whispers lines or Renban lines. All lines that share a colour have the same constraint. I.e if a blue line is a Renban line, all blue lines must be Renban lines.

Adjacent digits along a German whispers line have a difference of at least 5. The digits on a Renban line form a consecutive non-repeating set.

A Y clue is either an X clue or a V clue.

The digits on either side of a V clue sum to 5. The digits on either side of an X clue sum to 10.
