Division in the Pocket Dimension
(Published on 24. July 2026, 00:06 by AaronH)
This puzzle is based on the Tenth Box rule by Liamhere. If you enjoy this puzzle, I highly recommend checking out his fantastic The Tenth Box series.
The portal opens and you simply fall through - but where even is here? It feels similar, but also different, perhaps smaller than usual. All the rules seem the same, only somehow condensed. You decide to just act normal and hope everything else decides to follow your lead.
Rules
Normal sudoku rules apply: fill the grid with digits 1-9 so that no digit repeats in any row, column, or 3×3 box.
- The Pocket Dimension (Tenth Box): The nine centre cells of each 3x3 box (highlighted) form a "Tenth Box”, which must also contain the digits 1-9 without repetition. Each regular 3x3 box has all its clues projected on to the Tenth Box. Separate line segments remain as separate clues in the tenth box. In other words, the Tenth Box contains a copy of every clue in the puzzle. Example at AaronH.net/eg/tenthbox
All variant clues follow their standard meanings; full descriptions are provided below.
- Black Kropki Dots: A black dot between adjacent digits indicates one is exactly double the other.
- Parity Line: Along a red line, digits must alternate between odd and even.
- Modular Line: Along a teal line, any three adjacent digits must include one digit from each of the modulo‑3 sets {1,4,7}, {2,5,8}, and {3,6,9}.
