Kropki Cave Loop
(Published on 17. August 2024, 01:53 by yttrio)
Rules:
Normal Sudoku rules apply.
Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.
Adjacent digits along the loop must have a Kropki relationship. That is, they must either be consecutive or have a 2:1 ratio.
Digits in circles are on the loop, and give the total number of loop cells (including itself) seen in all horizontal/vertical directions combined. Non-loop cells block the vision.
Digits in squares are NOT on the loop, and give the total number of NON-loop cells (including itself) seen in all horizontal/vertical directions combined. Loop cells block the vision.
Solution code: Digits on the loop in row 7 (left to right) followed by digits on the loop in row 8 (left to right)

Really fun how I kept bouncing between making sudoku deductions and making kropki deductions.
