Which is Which?

(Published on 25. June 2025, 08:32 by lcy.30)

Normal Sudoku rules apply. (Put digits 1 to 9 in every row, column and 3x3 box.)

In this puzzle, a line is either a German Whisper Line or a Region Sum Line:
  • German Whisper Line: Two adjacent digits along the line have a difference of at least 5.
  • Region Sum Line: Box borders divide the line into segments with the same sum.

You must determine whether each line is a German Whisper or a Region Sum Line.

  • Black Kropki Dot: Cells separated by a black dot have a 1:2 ratio.

Try the puzzle on the SudokuPad app by Sven Neumann.

Hint: Start by determining the type of the line that begins at R6C1. Identifying the type of a line will assist you in determining the types of other lines.

Solution code: Row 9, from left to right.
