The goal of this puzzle is to separate three metal chain-links and then reassemble the chain. What’s so difficult about that? Well, the devil is in the details with this puzzle, and it takes some patience and a keen eye to solve. What’s more, the Chain Puzzle can actually be solved in three different ways, depending on which piece has been chosen as the middle link. That means once you have solved the puzzle, you still have two more tests to prove that you are a puzzle master! Chain Puzzle is another gem from the prominent Oskar van Deventer, a prolific puzzle inventor from The Netherlands. Mechanical Puzzles have a universal, international appeal that can’t be denied!
