Minimal Counting
(Published on 14. December 2025, 21:02 by Hiyou167)
Sudoku Puzzle Rules:
Sudoku
Put the digits 1–9 in each row, column, and box without repeating.
Renban (pink) Lines
Digits along a renban line form a set of consecutive digits in any order that don't repeat (e.g. 5423).
Minimum Squares
The digit in a minimum square must be smaller than its orthogonally adjacent neighbors. Any cell that meets these requirements is a minimum square.
Global Minimum Square Constraint
There are EXACTLY two minimum squares in each row, column, and box. A minimum square cannot appear on a renban line. It is your job to find them all.
Solution code: Row 9

Really fun puzzle with just the right amount of toughness. 1hr. Loved the star battle twist within.

What a cool variant of star battle! The negative constraint inflicted on Minimums led to a lot of cool logic.

LOVED this! The break-in took just the right amount of time, and overall solve was nearly 57 min, as it took me a while to get the hang of the minimal squares logic (I blame being under the weather). This was loads of fun and hope to see more puzzles with this concept!

78 minutes over two days, that was a slog. Nice idea!

Got stuck in the middle. The rest was smooth and beautiful.
