The Sliding Lock Puzzle is a delightfully mind-boggling device that is sure to keep your brain busy! Co-branded with Jean Claude Constantin and Kubiya Games, this puzzle utilizes both wood and metal in its design, a signature of German craftsmanship. The objective, as you might have guessed from the name, is to slide the three metal pins around the maze until you find the sequence that will make the lock handle pop open. If that sounds too simple, you're in for a surprise! However, with enough trial and error, creative thinking, and careful patience, any dedicated puzzler is sure to be successful. Best of luck!
