The biggest peculiarity of this model is its appearance and overlaps on the top and bottom of the cage. The cage, made of a single piece of material, has atypically six holes and, thanks to one of the largest, a higher difficulty. The roundness of the cage corresponds to the roundness of the holes. The inner and outer perimeter of the top and bottom of the cage has a stylish inner groove around the perimeter. The puzzle has been chemically-anodized in a metallic shiny finish, giving it a luxurious look.
Goal: Pull the spike roller out of the cage and then put it back in.
