ABSTRACT:
A puzzle is described made up of a plurality of parts which are assembleable/disassembleable. The parts are connected to one another via mating knobs and cavities which are tapered so that the parts move linearly with respect to one another. The parts in the embodiments described are only assembleable/disassembleable when they are in the right linear position with respect to one another and there is rotation. In some embodiments the parts making up the subassemblies must also be in the correct order, whereas in other embodiments the order is intentionally made variable.
