250 Move Schloss Puzzle Lock - Constantin Puzzle Collection
The 250-Move Schloss Puzzle Lock is a marvel of fine German craftsmanship, and it shows in both design and execution. For this sequential puzzle lock, there is actually no physical key to the lock! Most puzzlers know, however, that there is always more than meets the eye, and there is always a solution. The objective of this puzzle is to slide the four metal pins in sequential order to pop open the lock. The pins are fixed in place and will only move when you use the right sequence. As the name suggests, there are a minimum of 250 moves required before you reach the solution. The Schloss Puzzle Lock is designed by puzzle master extraordinaire, Jean Claude Constantin, and co-branded with Kubiya Games.
