Hidden German Whisper: Sum Up

(Published on 11. September 2026, 12:00 by 72kchunshuai)

This is part 3 of my Hidden German Whisper series.

Part 1: Warm Up

Part 2: Follow Up

Part 3: Sum Up

Part 4: Trinity

Rules:

  • Normal Sudoku rules apply: Place the digits 1–9 once each in every row, column, and 3x3 box.
  • Region Sum Lines: Box borders divide each blue line into segments with the same sum.
  • Hidden German Whisper: Hidden beneath each Region Sum Line is at least one German Whisper line. Each German Whisper line is at least two cells long, and lies entirely beneath the Region Sum Line. Adjacent digits along a German Whisper line must differ by at least 5.

Solution code: Box 5, in reading order, nine digits in total.

All three puzzles have been brilliant, thank you. As part four is called Trinity, I'm guessing it has all three previous lines in the ruleset plus the Hidden wihsper lines.
