“This fabulous puzzle by Osanori Yamamoto has already been reviewed by me after I bought it direct from the master himself. In fact Allard has just reviewed it as well (summary – he loved it!) It won a “Top 10 vote getter” prize in the 2022 IPP Design competition and I am so glad that it is being produced in greater numbers than Osanori-san can manage – EVERYONE should get a chance to try this puzzle. The aim is to assemble 6 identical T-shaped tetrominoes inside the cubic box in such a way that all the gaps are filled. It has a nice “almost there” solution (with a visible gap) but the true solution requires several lovely Aha! moments. It is actually quite difficult – one of the great puzzlers out there, Naoaki Takashima, had shown it off as one of his puzzles of 2022 (alongside 3 other very serious puzzlers). When Naoaki-san had showed it off he had announced that he had placed a few of the pieces inside and couldn’t even work out how he had done it and couldn’t remove them. If a puzzler as good as this struggled then it has to be a significant challenge. Even having solved the original version, I struggled to solve it again after a gap of a few months – I remembered the tricks but still couldn’t put all of them together into one solution without a struggle. I have to say that this is one of those “essential purchases” from this Pelikan release.”
This puzzle was crafted in Europe with absolutely fantastic quality. Each of the puzzles of Pelikan design are unparalleled in their class! Every piece of the puzzle is precisely cut and very well made; you cannot find its equal anywhere else. The diversity in wood makes each puzzle a unique masterpiece.
