Zipper Loop
(Eingestellt am 11. September 2025, 01:10 Uhr von ThePedallingPianist)
Check out other puzzles in my loop drawing series.
Rules:
- Normal sudoku rules apply.
- Draw a single one-cell wide loop that moves orthogonally between cells and does not branch or touch itself (not even diagonally).
- A pair of digits separated by a white dot are either both on the loop or both off the loop.
- Box borders divide the loop into Zipper lines with an odd number of cells (length 1 is allowed).
- On a Zipper line any pair of digits that are the same distance from the line's central cell, sum to the digit in that center cell.
- Cells with a lavender diamond are on the loop, and show the center of a Zipper line.
- If the loop enters a box more than once each loop segment is considered independently.
- Digits separated by a black dot are in a 1 to 2 ratio and digits separated by a white dot are consecutive.
Lösungscode: Row 9

Very fun and original. Not easy but it has nicely incremental steps forward, I never felt stuck despite taking a fair bit of time to solve.
