Polarity Loop
(Published on 8. September 2023, 20:31 by yttrio)
Rules:
Normal Sudoku rules apply.
Digits in cages cannot repeat and must sum to the total given in the upper left corner of the cage.
Cells separated by a white dot are consecutive. Not all dots are necessarily given.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
-- The loop must occupy all cells of all given cages.
-- Adjacent digits on the loop must alternate polarity (low [1234] vs high [6789]). 5 cannot be on the loop.
Solution code: Row 5

Beautiful! I had to restart too many times (for reasons entirely my own fault), but the puzzle was so good I just had to finish it
