标题: 8X8 魔方

用 64 块相同的小正方体 (有一面是黑色 ) 拼成 8X8 的一层 “魔方 ”，转时必须一行或一列同时转，用什么方法可以把全部黑面转向上？

It is hard to describe. So I will try my best but you have to guess a little.

Lets start from the top row. starting from the left most cube, will rotate each cube so that its black face is on the left. When done, rotate each column to make the black face forward (toward you). Then rotate the row so that the black faces are up. Then we do the second row. Note that what ever we do to this row, the first row will not change. After all rows are done, we rotate each row back so that the black faces are forward again.

Why 8 x 8? Isn't 2 x 2 the same?

So you let the 8X8 plane stand facing you, right?

Yes, 2X2, nXn are all the same.
