Boogie
(Published on 21. March 2025, 05:18 by Andrewsarchus)
About:
- A collaboration between Andrewsarchus and ThePedallingPianist
- In response to a Scojo setting prompt:
...I want you to pair up with someone you've never collaborated with before. Each of you should choose one variant, and set a puzzle together using just those two rules!...
-
Our chosen constraints:
-
ThePedallingPianist: Full Rank
Andrewsarchus: Zipper Lines
Rules:
- Sudoku: Within the main grid (inside the thick border), fill every cell with a digit from 1-9 such that digits do not repeat in a row, column, or box.
- Zippers: Pairs of values equidistant from the centre of a lavender Zipper line have the same sum. Where the centre lies in a cell, the sum is the value in that cell. The sum may be different for different lines.
- Full Rank: A value in an external cell represents the rank of the number formed by reading the digits in that row or column from that direction, where (1) is the lowest such row or column and (36) is the highest. (The 36 numbers are distinct - no ties).

Some tough but very interesting logic and great use of the full rank clues.

I love the puzzle and don't understand why the rating is kinda low?

Great puzzle with superb use of the full rank constraint, which is a bit of a pain with scanning. Thank you
