Whispers all around
- Whisper lines
- Little killers
The brief
Normal irregular 7x7 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 7. Adjacent digits on the green whisper line have a difference of at least 4. On the marked diagonal digits sum to the little killer clue outside the grid. (If there is no conflict with other rules, digits on the diagonal may repeat.)
