4×4或6×6网格——非常适合初学者和儿童
什么是迷你数独？
迷你数独使用较小的网格：流行的4×4版本在四个2×2宫中使用数字1-4，而6×6版本在六个2×3宫中使用数字1-6。规则与标准9×9数独相同，但按比例缩小。迷你数独非常适合向儿童介绍数独逻辑、用于快速谜题会话，或作为处理更大网格前的热身。

| 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. | 高级 |

什么是迷你数独？
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.
