什么让数独变得邪恶

邪恶数独不仅仅是一个给定数更少的困难谜题。定义其评级的是 技巧简介:在解题的某个时刻,单数、对子和宫线排除都用完了,唯一的前进方式是高级模式。这里的每个邪恶谜题至少需要一种重量级技巧—— X翼,其中锁定在两行两个单元格中的候选数从两整列中删除该数字;一个 剑鱼,三行三列的相同概念的扩展;或者XY链,其中链接的两个候选数单元格在棋盘上传递隐含关系,直到某个数字被强制。

在实践中,这意味着解题发生在铅笔标记中。预计早期会填满完整的候选笔记,在长时间没有单元格解析的安静阶段工作,然后当关键模式出现时,一次解锁五六个放置。这种节奏——干旱、突破、级联——是邪恶网格的特征。关键是,这都不是猜测:每个谜题都有一个唯一的解和一个完整的逻辑路径。

邪恶 vs 专家 vs 极端

邪恶介于...之间 专家 和 极端 在我们的阶梯上。一个诚实的比较:

级别 所需的最难技巧 铅笔标记 典型解题时间
专家 隐性数对,偶尔的X-Wing 有帮助 10–25分钟
邪恶 X翼、剑鱼、XY链 必要 20–45分钟
极端 长链,多个叠加的鱼 必要,严格管理 40分钟以上

诚实的建议:如果专家谜题仍然需要你半小时以上,在那里多停留一会儿——邪恶只会让你沮丧。如果你能轻松完成专家网格但极端感觉像一堵墙,邪恶正是你想要的桥梁:它需要高级模式而没有残酷的链深度。当邪恶开始变得常规时, 极端数独 在等待。如果表格中的任何技巧不熟悉,请完成 数独规则与技巧指南 首先——阅读十分钟可以节省数小时的凝视。

邪恶数独 — 常见问题

Is evil the hardest Sudoku level?
Almost. On 数独, evil sits one step below extreme — the absolute top tier. Evil puzzles demand advanced techniques like X-Wing and Swordfish, while extreme adds even longer chains and sparser starting grids. If you can finish evil puzzles consistently, extreme is your next stop.
How long does an evil Sudoku take to solve?
Most experienced players need 20 to 45 minutes per puzzle. Solvers fluent in fish patterns and chains can finish in 12–15 minutes, while a first attempt can easily take over an hour. Speed comes from recognising patterns quickly, not from writing faster — expect your times to drop sharply after your first ten puzzles.
Can evil Sudoku be solved without guessing?
Yes. Every evil puzzle on this page has exactly one solution and a complete logical path to it. You never need to guess — but you do need advanced eliminations. If you feel forced to guess, there is almost always an X-Wing, Swordfish, or chain you have not spotted yet.
What techniques do I need for evil Sudoku?
Beyond singles and pairs, you should be comfortable with pointing pairs, hidden pairs, X-Wing, Swordfish, and simple XY-chains. Full pencil marks are essentially mandatory — evil puzzles are solved in the candidates, not in the cells.
Is evil Sudoku free to play here?
Yes — every puzzle is free, with no signup, no download, and unlimited new puzzles. Creating an account is optional and only needed if you want your times and scores saved to the leaderboard.
