This heavy wire puzzle is about as simple as any you’ll find. Bosun Metal Puzzle is so sturdy, made of heavy nickel coated metal and virtually indestructible. It would make a good stocking stuffer and something to amuse young and old alike. To someone who thinks they can never solve these types of puzzles then they will be pleased and even surprised when they solve this one. Last night, while I’m out to dinner with 6 adults and one 7 year old boy, I brought out one of these simple wire puzzles and it got everyone’s attention. It quickly made the time pass as we waited for our dinners to arrive. You can purchase this puzzle at Amazon.
