- Whisper lines
- Renban lines
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Green lines are German Whispers: cells with a green line between them must differ by at least 5.
Purple lines are Run On Renbans: any sequence of five cells along the purple lines must contain a run of five consecutive digits in any order without repeats (like overlapping five cell renban lines).
