## 前言 | ||
三阶魔方英文叫 [`The Rubik's Cube`](https://en.wikipedia.org/wiki/Rubik's_Cube),它的发明者是匈牙利结构学家 [*Ernő Rubik*](https://en.wikipedia.org/wiki/Ern%C5%91_Rubik)。 | ||

||
### 第一层 | ||
|
||
I. 白色小花 | ||
|
||
> 目标:顶部黄心四白棱 | ||
白色块三个位置: | ||
|
||
1. 中间层白棱:向上转一下即可;如果顶部已经有白棱,旋转下面两层再向上 | ||
2. 底面棱:旋转 180 度即可,如果有冲突同上处理 | ||
3. 上层或下层外侧棱:向左或向右转动一次转化成第一种情况 | ||
|
||
II. 白色十字 | ||
|
||
> 目标:白色十字且外侧棱块与四周中心一致 | ||
中心黄朝上,将棱块与中心对齐后,旋转 180 度将白色花瓣转到底面 | ||
|
||
III. 底层还原 | ||
|
||
> 目标:底面全白,且底层外侧面完成 | ||
1. 白角块在顶层且在外侧,将另一个色块旋转至同色面,白面向左或向右,上去下回 | ||
2. 白色块在顶层且在顶面,将另两个色块放在对应面的中间,做 `三次` 上去下回 | ||
|
||
### 第二层 | ||
|
||
> 目标:第二层颜色还原(将黄色全部移到上层) | ||
I. 顶层有不含黄色的棱块 | ||
|
||
1. 在顶层找到不含黄色的棱块,如上绿下橙 | ||
2. 将橙色块与面对齐,旋转顶层(向左或向右)远离绿色面 | ||
3. 在绿色面,上去下回;调整白色面到对应手,上去下回 | ||
|
||
II. 将中间层不含黄色的棱块移动到上层 | ||
|
||
1. 将对应棱块放在左手或者右上,上去下回 | ||
2. 将白色面对准,上去下手 | ||
3. 变成第一种情况,调整上层棱块 | ||
|
||
### 第三层 | ||
|
||
I. 顶层黄十字 | ||
|
||
1. 黄色直线:将直线横放,正面顺时针转 90 度,右手上去下回,再将正面逆时针转 90 度 | ||
2. 黄色拐角:将拐角空位放在右下角,同上操作转化成直线 | ||
3. 只有黄点:任意摆放,做三次步骤一 | ||
|
||
II. 黄色面 | ||
|
||
> 目标,黄色面完成且另两层保持不乱 | ||
1. 将黄色面放到下面,旋转黄色面将非黄色块旋转到右下角 | ||
2. 右手做 `两次` 上去下回,如果右下角底面变成黄色则到三,否则继续做 `两次` | ||
3. 继续旋转底层重复步骤一、二,直至黄色面完成 | ||
|
||
III. 口袋 | ||
|
||
1. 找到一个口袋(凹型)面对左手,右手做 `三次` 上去下回,白色面放左手,左手做 `三次` 上去下回 | ||
2. 复原黄色面,变成三个口袋或者四个口袋 | ||
3. 三个口袋:找到最后一个拼好的面对自己,看对面口袋缺哪个颜色 | ||
- 就在对应的面(如右手)做 `一次` 上去下回 | ||
- 再反手(如左手)做 `一次` 上去下回 | ||
- 再回去(右手)做 `五次` 上去下回 | ||
- 再反手(左手)做 `五次` 下去下回 | ||
4. 四个口袋:随便找一面对自己,做步骤三 | ||
5. 0 个口袋:任意面对左手,做步骤一 | ||
6. 只有一个面拼好:等于一个口袋 |
