Kevin Sadler writes about this puzzle:
"I initially thought that the enormous entry hole through which the 3 rather complex pieces need to be inserted would make for a significantly easier challenge and, oh boy, was I wrong about that. Whilst it initially appears like there is a 2x2x2 sized hole for entry, it actually is even larger than that due to the fact that the bottom corner slopes gently down indicating that this puzzle is based on a much bigger grid. Obviously once solved the hole should be completely filled and that in itself is a huge problem. That sloping edge also makes movement of the pieces much more difficult. If anyone says that only 3 pieces makes for an easy puzzle then laugh at them – with a disassembly level of 10.1.3 this is a massive challenge. Very enjoyable and a must buy for any Osanori fans!"
