Logic Masters Deutschland e.V.

Rules:

• Normal Sudoku rules apply. Place the digits from 1 to 9 once each in every row, column, and 3x3 box.
  
• Kropki Pairs: Digits separated by a black dot are in a 2:1 ratio. Not all dots are necessarily given.
  
• Renban Lines: The blue and purple lines are renban lines. Digits on a renban line must form a set of consecutive digits in any order, without repeats.
  
• Modular Lines: Every line, including every renban line, is a modular line. Any three adjacent digits along a modular line must contain exactly one digit from each modular set. The modular sets are (1, 4, 7), (2, 5, 8), and (3, 6, 9).

Enjoy!
