Whisper Loop-de-Loop
(Published on 25. May 2023, 17:57 by yttrio)
Rules:
Normal Sudoku rules apply.
Digits in a cage must not repeat and must sum to the number in the top left corner of the cage.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- The loop must enter at least one cell of each cage.
-- Numbers on the loop count as double their value when calculating cage sums. For example, a 2-cell cage summing to 10 may contain a 2 on the loop and a 6 not on the loop.
-- The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5). The original, undoubled value of the digit is always used for the purposes of the German Whispers constraint.
6x6 Example:
The image below shows a sample 6x6 puzzle and solution with the same rule set.
Note: For 6x6 Sudoku, adjacent digits on a German Whispers line must have a difference of at least 3 (instead of the usual 5)
Play the example 6x6 in f-puzzles.
Play the example 6x6 in SudokuPad.
Solution code: Row 8 followed by column 2 (18 digits no spaces)

Had to restart, but finished it on my second try. Not to difficult, when your mind aligns with the logic. Well set puzzle!

Oh wow. Beautiful puzzle. Came here from Paquet Voleur's puzzle which I am not able to solve yet. But glad I was able to solve this. Really liked the ruleset.
