Marble Cake Plus is the sequel to Boucher's excellent Marble Cake packing puzzle. The cage is modified with one unit open and a lid and bottom are introduced. The seven pieces must pack into the box in a very specific order. It's a very difficult puzzle since there are many ways the pieces can fit in, but only one assembly which works with the box constraints. The piece with half unit offsets only makes things worse. Definitely a must have for the interlocking or packing puzzle collector.
Construction of this puzzle is outstanding, with a very nice fit.
