The puzzle is to disassemble and reassemble the 12 piece burr so that all the decorative routing is symmetrical.
The puzzle can go together in two different ways. One way, without the decorative routing symmetrical, is how the puzzle is presented when sold. You will have to completely take it apart so that you can then put it back together with all the routing symmetrical. This is a lot more difficult than it may first appear.
