Rules:

Normal Sudoku rules apply.

The grid is filled with loops containing alternating German Whisper and Renban lines. The length of lines within a loop are the same but may vary between loops.
• Loops cannot move diagonally.
• The length of a line may not exceed 5.
• A loop does not branch, cross, or be inside another loop.

Fog of war:The grid is covered in fog. Placing correct digits will clear nearby fog (no guessing is required).

Renban lines: digits on the purple line form a set of consecutive digits in any order.

German Whisper lines: adjacent digits on the green line must differ by at least 5. Digits on a line may repeat if allowed by other rules.
