Frederic Boucher wrote about it:
“I revisited my original design and added a piece: the token with Smiley on it 🙂 Obviously, when the puzzle is solved, Smiley must be completely hidden in the box, along with all the pieces.”

Kevin Sadler wrote about it:
“The fourth (and final?) puzzle in this wonderful Cubi series is a really tough challenge! There are 3 beautiful grained woods. The box has a slightly limited entry due to the attachment of a 1x2x½ voxel piece across one corner. The pieces are rather complex with 2 ½ voxel pieces attached to each one. There is also a disk with smiley face on it to be added inside. This is another one where it would be best to assemble a cube outside the box and the work out how to get it inside. Burrtools won’t help you as a rotation is required but it can help you search for cube assemblies. I needed this help and found 57 possible cube shapes but as soon as you adjust it to leave the 1x2x½ voxel gap, it is reduced to a single possible solution. In the interest of time, I used this to find the position of a single piece and then worked from there. It still took me quite long time to find a solution outside the box. Assembling it inside was a lovely sequence! I am sure that all you fabulous puzzlers will manage this without resorting to Burrtools.”
