From time to time, there is an original puzzle that is made again using 3D printers and it seems the case for many Oskar's puzzles. This time let me introduce you with Hysteresis Key puzzle.
The goal is, by moving back and forth the "drawer" to release it from its base. If you move too far the key, the puzzle will reset by itself.
The original puzzle (on the left) is pretty hard to solve because it's a blind solve and you cannot see the path at all, while on the right you can see it. However, you still need to anticipate how the pin will go depending on the obstacles.
The other (obvious) difference between the original and the 3D printed one is about the materials used that were plastic and metal originally, making is heavier.
In my opinion, it's a very clever design and luckily it was made it again so I can finally understand the internals!
You can also still challenge yourself by hidding the path, and try to map it like a revomaze.
The puzzle can be found on Puzzle Master website!
