There are 2 marbles enclosed in the puzzle on a curved ramp.  Can you get a marble in each of the two holes on either end? Amazing puzzle in that people will spend hours trying to solve it, yet when you know the "secret" you can solve it almost instantly. Great fun and an excellent desk or coffee table type of item.
