Why Mini Sudoku?
A friendly start for beginners and kids
Mini Sudoku uses a 6×6 grid with fewer digits than classic 9×9. The Hard (Advanced) preset is a gentle way to learn scanning and elimination—ideal for children, complete beginners, and anyone who wants a short logic break.
Switch between 4×4 and 6×6, pick a difficulty, and practice the same row, column, and box rules as full-size sudoku—just on a compact board you can finish in minutes.
Why we recommend it
- Easier to scan: fewer cells mean faster pattern spotting and less fatigue.
- Kid-friendly length: short rounds that fit between homework or family time.
- Builds confidence: master small grids, then move up to standard 9×9 sudoku.
What Is Hard 6×6 Mini Sudoku?
