Soma Burr is an interlocking Burr puzzle, made of Soma Cube pieces glued to surrounding castellated squares. When the puzzle is together, then only one move is possible, namely sliding out the red piece. This unlocks further pieces, and the puzzle can be taken apart. The object is to put the puzzle together again. This is challenging, because not all assemblies that fit together can actually be put together.
