“Another brilliant design by Osanori Yamamoto. When you see that name you should straight away think of rotations. This puzzle has been beautifully made by Pelikan with perfect tolerances and a couple of tiny magnets prevent the pieces falling out of position. There are a good few linear sliding and rotational movements possible and careful analysis of the board shapes is required to get the pieces into just the right positions to allow a clever rotation to occur. After a few more moves the first piece comes out. I expected the other piece to come out linearly after that but no, Osanori would never make it that easy. There are 2 choices for the last piece – both require more shuffling and rotations. A similar but opposite movement to the first piece surprisingly failed. Further thought and I had 4 separate gorgeously made pieces. I heartily recommend scrambling the pieces and leaving them a while before reassembly. Then you have a real challenge on your hands!”
