Zippularity

(Published on 3. August 2024, 06:04 by FullDeck-Missing)

Normal sudoku rules: Every row, column, and box must contain a complete set of the digits 1-9.

All lines are both Zipper AND Modular lines.

Zipper Lines: Along Zipper lines, pairs of digits equidistant from the center of the line have the same sum. For Zipper lines of odd length, that sum is the central digit on the line.

Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3.

A note about difficulty: On our website, Missing Deck Puzzles, we categorize our puzzles as

  • Brassica
  • GAS
  • Mild Indigestion
  • Indigestion
  • Strong Indigestion
  • Heartburn
We generally only our Mild Indigestion and higher puzzles on LMD, with Indigestion usually corresponding roughly to 1-2 stars on LMD and Heartburn anywhere from 2-4 stars on LMD. We don't typically share here our GAS or Brassica puzzles but please go explore our archive if you'd like to see some of those. GAS corresponds to the original daily GAS puzzles, where "hats" were awarded for times on the order of 5-10 minutes. Brassica puzzles are intended to be much easier, suitable for beginning solvers.

We categorized this puzzle as Heartburn.

The opening to this felt pretty hard, but once it started to flow it was much easier so I guess overall 3/5 here too. Maybe I was just looking in the wrong place!

Thank you for this fantastic puzzle, FullDeck-Missing! The deductions arising from the hybrid zipper/modular lines were incredible. In the beginning, it felt like I had to work hard to get any progress. But the more I thought rather in arithmetic than in sudoku/pencil-marking terms, the more I understood about the puzzle and it started to flow beautifully. Thank you for setting and sharing this gem!
