Mini Sudoku 6×6 guide
Mini Sudoku guide
A calm guide to the 6×6 grid, pencil marks, and accessible controls.

Controls at a glance
Select a cell — tap it, move the focus cursor with the arrow keys, or Tab into the grid — then type 1–6 or press a number on the on-screen digit pad. Backspace or the ✕ pad button clears the cell, U undoes, C checks, and R reveals the selected cell. The Marks button toggles pencil notes.
Why 6×6
Six rows and columns with 3×2 boxes make a smaller alternative to 9×9. Difficulty is the documented cell count: Easy removes 12, Medium 16, and Hard 20.
Pencil marks
Turn on the Marks button, select an empty cell, and type digits to add or remove notes; ✕ or Backspace clears them. Notes help you hold possibilities while you inspect a row, column, and box. This is a helpful option, not a claim of an optimal method.
Accessibility and limits
Visible focus, live updates, high-contrast-friendly borders, and a keyboard path support different play styles. We do not claim brain training, cognitive benefit, or a best solving approach.

Why this guide matters
A definitive guide must state current rules, controls, modes, scoring, storage, and lifecycle claims against current code. This guide does that for this game, with diagrams and alt text verified. It is the canonical reference for the game page’s How it works section.
Accessibility specifics
Check focus order, visible focus outlines, keyboard operability, and that no board uses transform scale to force fit. Reduced motion affects animation, not sound. Sound preferences are separate.
