Logic Masters Deutschland e.V.

Rules:

• Standard Sudoku rules apply. Every row, column and 3x3 box contains each number from 1 to 9 exactly once.
  
• Killer Cages: Digits in a cage cannot repeat and must sum to the small number in the top left corner if given. In this puzzle, each cage total is divisible by 6.
• Modular Lines: All edges of the cube are Modular Lines. 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).
  
• Renban Lines: The orange, blue, and yellow edges of the cube are Renban Lines. Digits on a Renban Line must form a set of consecutive digits in any order, without repeats.
  

Clarification: The black lines are only Modular Lines. All other lines are both Modular Lines and Renban Lines.

Enjoy!
