Vinco Soma

This difficult puzzle is designed by Dr. Volker Latussek and has been made with exquisite workmanship by Vin&Co. The goal is to fill and support the top layer of the box with the halved seven parts of the soma cube in an antisliding way. In other words, the box will appear to be completely filled when you have solved it, and pieces won’t move or slide inside the box, even though there are several voids inside that will not be apparent.
Solution included.
