On and off (8x8 Rellik/Whispers/Nabner sudoku)
(Published on 16. February 2024, 14:54 by sujoyku)
- Normal irregular 8x8 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 8.
- Rellik Cages: All cages are Rellik Cages. Any combination of one or more digits within a Rellik Cage CANNOT sum to the value in the top left.
Example: A Rellik Cage with given value 6 may not contain 1
- Whispers lines: Adjacent digits on a green line must have a difference of at least 4.
- Nabner lines: The golden lines are Nabner lines, i.e. on a golden line there may not be consecutive or repeated digits.
Example: If a 5 lies on a Nabner line, this line may not contain another 5 and neither a 4 nor a 6.
Here you can solve the puzzle online:
Solution code: Row 5 from left to right (8 digits in total)
