X-beliebiges Geflüster
- Whisper lines
- X-sums
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.
- X-sums: A clue outside of the grid indicates the sum of the first X digits in the respective row or column where X is the first digit seen from the clue.
- German Whispers: Adjacent digits on a green line must have a difference of at least 5.
