“This one is, in my opinion, the most difficult among the four CUBI puzzles released by PELIKAN. But with some logic and perseverance, everything should fit completely into the box :)”

“Whilst this is the 4th in the series if you take them in ascending numerical order, it probably should be the third that you try. Jakub and team have made this absolutely gorgeous from Zebrano with a Mahogany box. Again there are a number of pieces to place inside the box which has a couple of half-voxel pieces stuck to the walls. These half voxel interfere with your ability to place the in the box and also will form part of the eventual cube shape. To make it even more difficult this time, several of the pieces are made with half voxel lengths on one or more places. This will make it seriously tough to assemble the cube shape. After I failed for a while, I counted the total number of voxels on the pieces and there are 25 in all plus the 2 halves stuck on the walls (not much room to manoeuvre). I decide to try and make a cube shape outside the box with half voxel gaps in the crucial positions. I’m not very good at Soma cube puzzles and this is similar but much harder. It took me over an hour to find a cube shape – remember, the half voxel shapes make all the difference to your search. Having made my cube it was a lovely much smaller challenge to reassemble it in the box. Rotational moves and sliding is required. This is great fun and a wonderful next step up in difficulty!”
