4×4 或 6×6 網格——非常適合初學者和兒童
什麼是 迷你數獨？
迷你數獨使用較小的網格：流行的4×4版本在四個2×2宮中使用數字1–4，而6×6版本在六個2×3宮中使用數字1–6。規則與標準9×9數獨相同，但按比例縮小。迷你數獨非常適合向兒童介紹數獨邏輯、進行快速謎題練習，或作為處理較大網格前的熱身。

如何解 迷你數獨
| 技巧 | 它的作用 | 等級 |
|---|---|---|
| Direct Scanning | With only 16 cells and digits 1–4, scan each row, column, and 2×2 box for missing digits. Most easy puzzles resolve in a single pass. | 進階 |
| Single Candidate | If only one cell in a row, column, or box can hold a particular digit, place it immediately. | 進階 |
| Box–Row/Column Interaction | Each 2×2 box shares all four cells with exactly two rows and two columns. Every box placement simultaneously restricts two full rows and two full columns. | 進階 |

什麼是 Mini Sudoku？
Mini Sudoku is a compact 4×4 variant of classic Sudoku. The grid uses only the digits 1–4, and every row, column, and 2×2 box must contain each digit exactly once. It follows all the same logic as standard Sudoku but at a fraction of the scale.
How is Mini Sudoku different from regular Sudoku?
Mini Sudoku uses a 4×4 grid with digits 1–4 instead of a 9×9 grid with digits 1–9. There are 4 rows, 4 columns, and 4 boxes (each 2×2). Solving techniques are identical but the puzzles resolve much faster — typical solve times are under 5 minutes even for beginners.
Is Mini Sudoku good for beginners?
Excellent for beginners. Mini Sudoku teaches the core Sudoku logic — elimination, uniqueness, scanning — in a format that's quick to complete and easy to check. It builds the mental habits needed for larger grids without the time commitment.
Can all standard Sudoku techniques apply to Mini Sudoku?
Yes, but only the simplest techniques are needed for most Mini puzzles: naked singles and hidden singles. More advanced techniques like naked pairs or X-Wings exist theoretically but rarely appear in 4×4 grids. Expert Mini puzzles can require hidden pairs.
Is Mini Sudoku just for children?
Not at all. Mini Sudoku is used by puzzle designers, schools, speed-solving enthusiasts, and anyone who wants a quick but satisfying logic puzzle. Expert Mini Sudoku puzzles with minimal given digits can challenge experienced solvers despite the small grid size.
How long does Mini Sudoku take to solve?
Easy puzzles take 1–3 minutes. Medium puzzles take 3–6 minutes. Hard and expert puzzles can take 5–12 minutes even for experienced solvers. Mini Sudoku is ideal when you want a complete puzzle experience in a short time.
