How to play Mini Sudoku (6×6)
Mini changes the grid size to 6×6 and the box size to 2×3. It has its own puzzles, save slots, and high scores rather than reusing a cropped Classic board.
The rules
Fill each row, column, and 2×3 box with 1–6, without repeats. This smaller board has its own saved progress and high scores.
A useful first move
Use the same row, column, and box scanning as Classic, but work with 1–6 only. A smaller candidate set makes Mini a useful place to practice these deductions.
If a row contains 1, 2, 4, 5, and 6, its remaining cell is 3. Each outlined box is two rows high and three columns wide, and also needs all six digits.
Controls, difficulty, and saved games
Choose Beginner, Easy, Medium, Hard, or Expert above. Select an empty cell, then tap a number or use your keyboard. Notes let you pencil in candidates; three hints are available. Three mistakes end the puzzle.
Every mode and difficulty keeps a separate save in this browser. You can switch puzzles and return to your place. Clearing site data removes these saves; they do not sync with another device or the iPhone app. Settings include night mode and optional automatic cell advancement.
Correct entries earn points. High scores are stored by mode and difficulty and update only when beaten; completed-puzzle count and day streak are shared.
