 Voluta uses the same principle as the classic "Ball and Ring" puzzle, but it is much more difficult to solve. One of the reasons for this is that the piece that has to be removed does not fit through the round hole which takes the place of the slot in the "Ball and Ring" puzzle. Another reason is that during the process of solving the puzzle, the rope seems to tangle — at this point most solvers get discouraged and scramble back to the original position to start over. |
