Little Whisper Miracle
- Whisper lines
The brief
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Little Killers: The digits on each marked diagonal sum to the same total which has to be determined by the solver. (If there is no conflict with other rules, digits on such a diagonal may repeat.)
- German Whispers: Adjacent digits on a green line must have a difference of at least 5.
