The task most difficult for an apprentice blacksmith was to forge two pieces exactly alike. (introduced 1999)
Very Difficult category designs are characterized by a large number of moves in the solution. Additionally, these designs can also have many 'false' moves that do not have anything to do with the solution. False moves must be undone before the correct solution can be followed. Concepts learned at other levels are combined in the very difficult level. Experience recommended.
