地球仪魔方Masterball的来源研究

大烟头

这是Masterball，地球仪魔方。

发明者：Geza Gyovai匈牙利人，现在生活在苏黎士。他花费6年时间的设计才发明出来。

又有人是这样介绍的：

智力球MASTERBALL是德国的先进产品，由瑞士动力工程师Dr.G.Gyoval 经六年研究设计而成。此玩意极富挑战性，不但能考验智力、耐力，更能启发个人逻辑思考。

物品特色：智力球MASTERBALL球面是由大小32片色块组成，在这个神奇的组合里，每一个色块都能上、下、左、右轻易运转以拼合成各种不同的精美图案，故玩者可以在几乎无限的变化空间里发挥自己的创造力。
随球附送图解及说明一本，指导各种不同难题的进行。
智力球MASTERBALL较其他逻辑游戏更优越，它能够陪你从最简单的步骤，玩到最复杂的图块或色块组合。

誰是誰的誰

在当时就能够设计出这种结构，值得敬佩！

小桥流水人家

没想到烟头这么早就了解masterball地球了

原来大烟头早就发了这样一帖了啊，很详细！

呃，我眼花……里面还是有球的……

刚买到一个彩虹MASTERBALL，转的时候不小心就拆开了！正好一半一半。里面没有中间的球呀？就是两半，像西瓜皮似的。我当时就装上去了，也不知道怎么拆的怎么装的。大侠教教怎么再拆开来呀，谢谢！

中间的球是不是就是用来固定轴的？我常常出现外面轴对不准内部轴的现象

对不起，我没有仔细看过。只是我不明白1、4和2、3有什么区别？

1  4可以

2  3不可以

对中间的2 3层不好用

Phase 1: Put pieces in their correct layers.

1. Find any piece in the top hemisphere (cap or band) that is not in the correct layer.
2. Hold that piece at the front, just to the left of the seam. (On the Logi-Vip sphere, you probably have to turn the layer to get it there.)
3. Find a piece in the opposite layer that does not belong there.
4. Turn that opposite layer until the wrong piece lies at the front, just to the right of the seam.
5. Do this sequence:
   1. Twist the right hand side of the ball.
   2. Shift the layer containing the two pieces to the right, so both pieces cross the seam.
   3. Twist the right hand side of the ball again.
6. Repeat a-e until all the pieces are in the correct layer.

Phase 2: Solve two opposite layers.

1. Find in any layer two adjacent pieces that you want to swap.
2. Hold those pieces at the front, one on each side of the seam. (On the Logi-Vip sphere, you probably have to turn the layer to get them there.)
3. Find any two adjacent pieces in the opposite layer that you also want to swap.
4. Rotate that layer to bring them to the front, too.
5.  Do the following sequence:
   1. Twist the right hand side of the ball.
   2. Shift the top layer to the right.
   3. Twist the right hand side of the ball.
   4. Shift the top layer to the left.
   5. Shift the bottom layer to the right.
   6. Twist the right hand side of the ball.
   7. Shift the bottom layer to the left.
   8. Twist the right hand side of the ball.
6. Continue using steps a-e to do swaps in both layers until one of the layers is solved.
7. Find any adjacent pair in the remaining layer that must be swapped.
8. Turn the layer to bring it to the front.
9. Do the sequence of step e. This temporarily disturbs two pieces in the solved layer.
10. Repeat steps g-i for another pair, and this will also restore the temporarily swappes pieces.
11. Continue repeating g-i until either both layers are solved, or until one of the layers apparently needs a single swap.
12. If one layer apparently needs single swap, it really means that nearly all of them are in the wrong place. Simply pick one of the two 'swapped' pieces, and consider that one to be correct. Then use steps g-j to place the other 7 pieces correct relative to the chosen piece.

Phase 3: Solve other two layers.
This is the same as phase 2, except as applied to the remaining two layers. Finally, turn all the layers so that they match up.
