<p>Channel C runs right round the sphere. All the segments are located therein. They are moved into the correct position here. You can only rotate the segments in one direction in channel C. If a segment is to be rotated through 180 degrees, however, it can only be rotated in channel D, point E because segments can only be rotated at point E. The game can begin by the first segment being pushed downwards and the next segment being pushed into channel D, and this is repeated until all the segments are in channel D. The game is successfully completed when all segments alternately have the sun at the top and the moon at the bottom. 7-20 segments are used. <IMAGE></p> |
