Ambiguous Renbans and Whispers continue to be intriguing—this time with Region Sum Lines. Difficulty estimated at 3-3.5 stars. For a warm up, see Aftershock.


Rules:

Normal Sudoku: Place the digits 1 to 9 in every row, column, and 3x3 box.

Certainty—Region Sum Lines

  • Each line is a Region Sum line
  • Digits on a Region Sum line have an equal sum N within each box that the line passes through
  • If a line passes through the same box more than once, each individual segment within that box sums to N separately (note Box 2)
  • Different lines may have different sums

Ambiguity—Renbans or Whispers

  • Additionally, each line is either a Renban line or a German Whisper line, such that:
  • Digits on a Renban line form a set of consecutive digits in any order
  • Adjacent digits on a German Whisper line differ by at least 5
