Why Mini Sudoku?
A friendly start for beginners and kids
Mini Sudoku uses a 4×4 grid with fewer digits than classic 9×9. The Medium (Intermediate) 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 Medium 4×4 Mini Sudoku?
4×4 medium mini sudoku removes some clues while still guaranteeing a fair, logical solve. You will rely more on elimination and cross-checking.
Great for solvers who want a bite-sized challenge that still requires focus—sessions stay short but satisfying.

Mini Sudoku Rules (4×4)
- • Use only digits 1–4; each row must contain every digit once.
- • Each column must contain digits 1–4 exactly once.
- • Each 2×2 box must contain digits 1–4 exactly once.
- • Given clues are fixed; fill only empty cells.
- • Switch between 4×4 and 6×6 anytime—same rules, different grid size.
Tips for This Difficulty
- • Track missing digits per row—only four slots makes counting trivial.
- • Look for hidden singles in boxes when rows look crowded.
- • Avoid guessing; backtracking mentally is easy on 4×4 but costs time.
- • If you toggle draft mode, keep only two candidates per cell when possible.
