“Another brilliant design by Osanori Yamamoto. When you see that name you should straight away think of rotations. Allard Walker had already recommended this one and I had seen that another very talented puzzler had 3D printed it and spent 3 weeks before managing to assemble it. This made be ever so slightly fearful of this one. It has been beautifully made and is sent out disassembled with the pieces cleverly locked together. So far in 4 days of concerted play, a number of ideas have occurred to me but so far none have worked. In fact for 5 heart-stopping minutes I had everything locked together but couldn't get them apart at all! This is such a simple idea and yet tremendously difficult. I will keep going and hopefully not take 3 weeks!”
