Black Widows are a dangerous animal, but you don’t need to be afraid of our Black Widow. Made from nickel plated wire, this puzzle requires you to remove the string from the frame. While most string/wire puzzles can be extremely hard due to the easiness of accidentally tying knots, this one is actually easier than it looks when you analyze it in more detail. Don’t be intimidated by all the rings, they are there for a reason. From our PuzzleMaster Wire Puzzle collection.
