Tavern Puzzles evolved from reproductions of hand-forged artifacts that run from basic all the way to Complex (with intermediate and difficult between). Basic designs are often traditional and familiar and have fewer steps. They can look easy, but looking easy is not the same as being easy. The complex 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 complex level.
