Digits in cells separated by a white dot are consecutive. - Region Sum Lines: Box borders split blue region sum lines into sections and the digits on those sections must sum to the same value. All lines that cross the marked diagonal are region sum lines. - Renban line: Digits along a Renban line must form a set of non-repeating consecutive digits in some order. All lines below the marked diagonal are renban lines. - Whisper-4: Adjacent digits along a Whisper-4 line must differ by at least four. All digits below the marked diagonal are Whisper-4 Lines.
