Pointed Whisper Loop
(Published on 1. December 2023, 21:15 by yttrio)
This puzzle is the start of a loop series that uses arrow clues.
Rules:
Normal Sudoku rules apply: Place the digits 1 to 9 in every row, column, and 3x3 box.
Digits along an arrow must sum to the digit in that arrow's bulb.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- All arrow bulbs must be on the loop.
-- The digit in an arrow bulb gives the total number of loop cells in the 3x3 box containing the bulb.
-- The loop acts as a German Whispers line (i.e., adjacent digits on the loop must have a difference of at least 5).
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)

Solution code: Row 9

This is one of these puzzles that (even after years and years of Sudoku solving) still amaze me how on earth my brain is able to do this. Loved every bit of it!

This seemed daunting at first, but then the loop just kept growing organically, and things fell into place much more quickly than I had expected. A masterpiece!

I started this puzzle wondering how or if I'd be able to reach the solution (loop sudokus are awesome, but I find them very daunting). Then it just started making sense and I was able to start adding in digits! Great puzzle, thank you :-)
