什麼讓數獨邪惡

邪惡數獨不僅僅是給定數字較少的困難謎題。決定評級的是 技巧簡介:在解題的某個時刻,單一、對與宮行刪減都用盡,唯一的前進方式是進階模式。這裡的每個極難謎題至少需要一種重量級技巧——一個 X-Wing,其中一個候選數鎖定在兩行中的兩個格子,從兩整列中刪除該數字;一個 Swordfish,同一概念的三行三列延伸;或XY鏈,其中連結的雙候選數格子將推論傳遞到整個棋盤,直到某處的數字被強制。

實際上,這意味著解題發生在鉛筆記號中。預計早期就要填滿完整的候選數筆記,在長時間的寂靜中工作,沒有格子被解決,然後當關鍵模式出現時,一次解開五到六個位置。這種節奏——乾旱、突破、連鎖——是邪惡數獨的特徵。關鍵是,這都不是猜測:每個謎題都有唯一解和一條完整的邏輯路徑。

邪惡 vs 專家 vs 極難

邪惡介於 專家 和 極致 在我們的階梯上。一個誠實的比較:

等級 所需最難技巧 筆記 典型解題時間
專家 隱藏對,偶爾X翼 有幫助 10–25分鐘
邪惡 X-Wing, Swordfish, XY-鏈 必備 20–45分鐘
極難 長鏈,多層魚 必備,大量管理 40分鐘以上

誠實的建議:如果專家謎題仍然需要您超過半小時,請在那裡多停留一段時間 — 邪惡只會讓您沮喪。如果您能輕鬆完成專家網格但極限感覺像一堵牆,邪惡正是您想要的橋樑:它需要進階模式,但沒有殘酷的鏈條深度。而當邪惡開始感覺常規時, 極致數獨 在等待。如果表中的任何技巧不熟悉,請通過 數獨規則與技巧指南 首先 — 十分鐘的閱讀節省數小時的凝視。

邪惡數獨 — 常見問題

Is evil the hardest Sudoku level?
Almost. On 數獨, 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.
