感谢o仔的高清数码相机，这回有好图了 呵呵
澳大利亚产82年产的，颜色和彩虹球有区别，这个上下的块儿颜色不一样，从浅到深递进的，增加了还原难度，但是有定位，比彩虹球好转，解法和详细介绍在10和11楼，拍摄地点是肯德基聚会，然后被耗子切了去还原，另外入手了齿轮二号加升级版贴纸，难度不小，绝对精品

This nice puzzle is consists of a ball which is sliced up like an orange into 8 segments, and the whole is also divided horizontally into 4 layers (two polar caps and two middle bands). In other words, it is like a globe with 8 lines of longitude and 3 lines of latitude.

There are two types of move: A half turn of half the ball along any of the lines of longitude, called a slice move, or a 1/8 turn of one of the 4 layers.

On the standard puzzle, the Rainbow Master (sometimes known as the 'geomaster'), each of the 8 segments has a different colour. Other designs have pictures on them. The Rainbow version is easier than a picture version because the pieces occur in identical pairs in opposite layers.

The Masterball was invented by Geza Gyovai and patented on 15 August 1989, US 4,856,786.

A different version is the Logi-Vip ball, made by Arxon. It has a much simpler mechanism since it is made of two hemispheres and therefore only allows one type of slice move. To do the other slice moves, you have to turn all four layers to bring the seam to the right place. Because each piece is different, it is similar in difficulty to picture masterballs. When solved, the four pieces of a segment have the same colour but in different shades ranging from a light colour at one pole to a darker shade at the other pole.

The Logi Vip ball was invented by Hubert Petutschnig and patented on 11 June 1981, WO 81/01638.

回复楼上各位：比彩虹球早 这个
              刚拿回来由于年代久远有点涩 上了油好多了
              以后还得借相机才能有好图 哈哈
               机会难得啊 这个球

绝对无码啊。第一次发现原来1982年可收藏的魔方挺多的

解法如下：

JavaScript Rainbow Masterball
The number of positions:
There are 16 polar pieces and 16 middle pieces, giving a maximum of 16!2 positions. All of these positions are attainable. This gives 16!2 = 437,763,136,697,395,052,544,000,000 or 4.4•1026 positions. There are 16 possible orientations of the puzzle as a whole, so the actual number is 16!2/16 = 27,360,196,043,587,190,784,000,000 or 2.7•1025.
On the Rainbow Master the pieces come in identical pairs, so then the number of positions becomes 16!2/216 = 6,679,735,362,203,904,000,000 or 6.6•1021 positions. Dividing this by 16 to account for the puzzle orientation gives the approximate number of positions 4.1•1020.

Masterball homepage. Contains a solution for the rainbow master.
David Joyner's page. Some move sequences and patterns.
Cyril Castella's page. A French solution.
There are two move sequences that we will use repeatedly throughout the solutions. Hold the puzzle with one seam directly in front, facing you.
a.        The first sequence is used to pair up pieces in the middle bands, or in the polar caps. Suppose in some layer there are two pieces directly opposite each other, and that they actually belong in the same segment in the solved puzzle.
Then do the following:
1. Hold the puzzle with one of the pieces just to the left of the front seam (on the Logi-vip sphere you of course have to turn the layer to achieve this).
2. Move the layer to the right, so the two pieces cross the front or back seams.
2. Twist the right hand side of the ball.
3. Move the layer to the left.
This leaves the two pieces in the same segment without separating other such pairs.

b.        The second sequence swaps a pair of pieces in one segment with a pair in another segment. It is mainly used to line up the pieces in the polar caps with those of the middle layers. The pairs that are swapped also turn over, so it can also be used for orienting them.
To swap one pair of middle band pieces in one segment with those of the opposite segment, do the following:
1. Hold the puzzle with one pair of pieces in the segment just to the left of the front seam (on the Logi-vip sphere you of course have to turn the layers to achieve this).
2. Move the top band to the right.
3. Twist the right hand side of the ball.
4. Move the top band back to the left.
5. Move the bottom band to the right.
6. Twist the right hand side of the ball.
7. Move the bottom band back to the left.
This sequence can of course also be used on the caps instead of the middle bands.

Solution for Rainbow Master:
Phase 1: Pair up the pieces in the middle bands.
a.        Find any two pieces in the middle bands that have the same colour.
b.        Use any slice moves you need to places them in opposite segments.
c.        If they are now in the same band, then do sequence a to pair them up. If they do not lie in the same band, then try to find another pair of pieces to pair up.
d.        If you have done steps a-c as often as possible but cannot pair up all the middle band pieces, then use some slice moves to place an unmatched pair in the front segment, and a matched pair at the back segment, and do sequence b. You will now find that the unmatched pair can be solved using steps a-c above.
Phase 2: Pair up the pieces in the polar caps.
This is essentially the same as phase 1, except that you of course turn the caps instead of the bands when doing the move sequences.
Phase 3: Align the pairs in the middle bands and the caps to build segments.
a.        Find any pair of middle band pieces and pair of cap pieces that belong together in one segment.
b.        Use any slice moves to put them in opposite segments.
c.        Now do sequence b to put them all in a finished segment.
d.        Repeat steps a-c above to solve all the segments.
Phase 4: Put the segments in order.
Note that this phase is similar to solving the Saturn Puzzle, and that the simpler but longer solution shown there can be used as well.
In this final phase, only slice moves are needed. To describe the move sequences we need a notation for the moves, and for the different positions of the segments. Number the segment positions 1 to 8, where the front is position 1, the segment to its right position 2, and so on.
Name the possible slice moves A to D. A is the slice that turns over pieces 1 to 4, B is the slice move that turns over 2 to 5, and so on.
