Possibly the compass directions N, S, E & W which are printed on both sides of the puzzle will assist one in solving. But, maybe not! Rated as a level 6 difficulty by the manufacturer (Hanayama Puzzles of Japan) on a scale of 1 to 6 where 1 is easiest and 6 most challenging. Your experience could differ. Thought by many to be one of the best in this series of over 40 different brain teasers because the solution is at first elusive and then delightful once discovered.
