Strange Pattern

(Published on 21. December 2025, 03:13 by Chaotix37)

So I haven't set a puzzle for a long time.

Strange Pattern

Normal Sudoku Rules Apply. Each row, column, and 3x3 box, must have 1-9 without repetition.

Diagonal: Digits along the blue lines cannot repeat the same digit

Non-consecutive: Orthogonaly adjacent cells cannot be consecutive.

Solve in Sudokupad

Solution code: Negative Diagonal(Left to right, top to bottom) (Starting from Row 1 column 1, row 2 column 2, up to row 9 column 9)(9 Digits)

added orthogonaly in the adjacent

Was confused about wether adjacent meant kings move adjacent or orthogonally adjacent. Assumed wrong but after noticing i couldnt fill in numbers anywhere corrected and it was a pretty easy one! Fun pattern

9:40 for me. Indeed a strange pattern. After break-in everything came together easily.

Took me a good 20 minutes of crazy pencil marks before I found where to make progress. Great puzzle though!

A snack. Under 15 minutes. Thank you and merry Christmas.

The adjacency negative constraint made the ending very fast and the beginning painfully slow. Very nice puzzle but definitely 2 stars for me.

Delightful solve! Love the symmetry!

This took me 68 minutes. Most of that was spent staring at it before reading the rules and noticing the adjacency constraint. D’oh.
