还真是是8步啊。都说<=8步能解决，看来8步是极限喽！

以后比赛就用这个打乱~

作者: mengfl 时间: 2010-3-23 06:15:55

楼主研究的够深的。我也研究一下

作者: erictrui 时间: 2010-3-23 07:48:24

我想问一下你是做哪一面的十字，然后一开始又是以哪个面为底打乱阿？

作者: hanxian586 时间: 2010-3-23 08:43:44

果然是八步，不过用对面就比较好做了~~

作者: Vicki 时间: 2010-3-23 09:04:47

最多8步可以还原，不过8步十字的概率比较低~

作者: SaiMo 时间: 2010-3-23 13:47:38

回5楼做白底的十字啊打乱是跟同学pk的时候对方故意打乱成这样的

作者: robester 时间: 2010-3-23 15:14:33

资料不查了
印象中八步的概率在千分之几，反正不到百分之一。
所以这个贴子不能让新手误以为十字八步就可以了
其实六步的概率在一半左右，你的十字步骤应该经常出现六步才正常。

真的吗？不是说一切均可在7步完成么

作者: chenjunjian 时间: 2010-3-23 20:54:23

那要看你用什么做底了
