    # 3x3 魔術方塊解法 [toc] 家裡的(3x3)魔術方塊復原了嗎?解答掉了?可以參考一下這裡的[**解答**](https://rubiks.com/en-US/solve-it)! 雖然我現在使用的魔方解法不是上面那種,但也不是最快的,但應該是**公式最少**、**判斷最少**的那種吧?下面就是我目前使用解法的簡要紀錄說明。 > 但我已經忘記最早是從哪個 Youtube 影片看到學習的。 ## 基礎公式 公式大致就是以這個 **U'RUR'** 為基礎: - 上層右轉(**U'**) - 右側前轉(**R**) - 上層左轉(**U**) - 右側後轉 (**R'**) ![](https://hackmd.io/_uploads/By75kNK22.png) ![](https://hackmd.io/_uploads/SyHT1NFhh.png) 所以要先練習這個**組合技**,只要拿著解好的魔方,按照上面這個**組合技轉法**進行 **6 組(次)**,魔方依舊會回到原來解好的狀態。 ## 解法步驟 目前學到的解法,基本上還是**逐層解**,但每面都會形成**十字結界**,就姑且叫做**十字卍解**吧! :::success 一般起手式,都是拿**白色**和**黃色**對面的中心塊開始。 當然可以選擇自己喜歡的顏色,但是只要**一開始**決定一種顏色,另一面的顏色也就確定了(**紅<->橘**, **藍<->綠**),接著因為**公式解法**的步驟,也就會決定**後續**步驟的顏色了。 這裡是不是要有什麼人生體悟? ::: 1. 先以**黃色中心**做**十字白色**小花。 ![](https://hackmd.io/_uploads/r1g5xNthn.jpg) :::info **[公式]** 欸,這一步還不需要公式吧!靠的是膝蓋自信心。 ::: 2. 以**白色邊塊**相連的顏色,對齊各面**中心色塊**後,將側邊轉180度,在下方形成**白色十字**。 ![](https://hackmd.io/_uploads/H13hl4Fn3.jpg) :::info **[公式]** 唉,這一步應該也不用吧?!就是對齊**中心色塊**翻轉該側(**面對白色邊塊**的前面那層),完成**白色十字**。 ![](https://hackmd.io/_uploads/rklygbVtnh.png) ::: 3. 完成**第二層顏色**的同時,完成上方**黃色十字**。 ![](https://hackmd.io/_uploads/B1azW4F22.jpg) :::warning :construction: **[公式]** 這裡有! - **RU'R'** 或 **L'UL** ![](https://hackmd.io/_uploads/BJpBZ4t33.png) ::: :::success 其實公式轉法,就是多練習、多練習、多練習。練習成為**肌肉記憶**。 ::: 4. 接著完成**第三層邊塊**對齊,形成各面的**十字整合**。 ![](https://hackmd.io/_uploads/r12dWNK2h.jpg) ![](https://hackmd.io/_uploads/Hy4j-4F22.jpg) :::warning :construction: **[公式]** ::: 5. 將**白色十字**面置於**左方**,**黃色十字**置於**右方**。 6. 先進行**白色角塊**整理,只要完成 **3 角**,左右交換。 ![](https://hackmd.io/_uploads/r1ApbEthn.jpg) :::warning :construction: **[公式]** ::: 7. 進行**黃色角塊**整理,也只要完成 **3 角**。 ![](https://hackmd.io/_uploads/SklxG4Kn2.jpg) ![](https://hackmd.io/_uploads/S1NffNtn2.jpg) :::warning :construction: **[公式]** ::: 8. 左右**黃白角塊對齊**進行**交換**,即可**完成**! ![](https://hackmd.io/_uploads/H1FNM4Fh2.jpg) ![](https://hackmd.io/_uploads/ryw8MEFh2.jpg) ![](https://hackmd.io/_uploads/BJqOMNFhh.jpg) ![](https://hackmd.io/_uploads/ryzsMNK2n.jpg) :::warning :construction: **[公式]** ::: 是不是很輕鬆!常常練習,[**阿茲海默先生**](https://children.moc.gov.tw/book/229316)不會來喔。 ## 後記 想到我的第一顆魔方,就是早期文具店賣的,不是很好轉,顏色都是用貼紙貼的那種,即便如此在那個網路不發達的青澀年代,附有魔方[[**解答說明書**]](https://assets.ctfassets.net/r3qu44etwf9a/6kAQCoLmbXXu29TTuArrk1/404118e1f9bfb6f9997157a284bbc572/Rubiks_Solution-Guide_3x3.pdf),對我來說還是很有吸引力的! 不知道各位手邊有沒有**魔術方塊**?看到沒有完成的魔方,是不是有股衝動想要完成?不過要背很多公式[[**3 階魔方解法指南**]](https://assets.ctfassets.net/r3qu44etwf9a/6kAQCoLmbXXu29TTuArrk1/404118e1f9bfb6f9997157a284bbc572/Rubiks_Solution-Guide_3x3.pdf),人生都沒有這麼簡單,用公式就可以攻克?! > 這個版本好像就是隨贈的解答說明書。 為了要把不小心搞亂的魔方復原,只好用不是很靈巧的雙手和不是很靈光的膝蓋,按照解答一步一步完成。當然,隨附的解答方法不是最佳解,而且**公式超多**,要符合條件使用公式的**判斷超多**,只要一陣子沒練習,就會全部忘光光!最後就會用**終極拆解法**來處理,相信很多人都會這招吧?! 所以有機會逛 81 文具賣場時,往往就會飄移到賣魔方的區域!耳邊就會響起:還要買啊,家裡已經有一個了! > 上面這個就是磁改版,好轉!
