Loopy Whisper X-Sums
(Published on 8. June 2024, 04:31 by yttrio)
This puzzle continues a loop series of sorts where the clues are external clues. Previous puzzles in the series are linked to below:
Loopy Whisper 'Wich
Killing Me Softly With His Loop
Rules:
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).
Clues outside the grid are loop-cell X-sums. They indicate the sum of the first X digits on the loop in the row or column, where X is the digit next to the clue (and not necessarily on the loop). X cannot be larger than the number of loop cells in the row/column.
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 SudokuPad.
Solution code: Digits on the loop in row 3 (left to right) followed by digits on the loop in row 6 (left to right)

Gorgeous!
The 6x6 version was surprisingly intricate as well.

This series is so cool! I love how it takes clues we're already familiar with and brings some fresh juicy stuff out of them.
