A fascinating lock made from two contrasting wood colors. This lock doesn’t need a key to open. Instead, your task is to move the slider horizontally and pull the platform so you can open it. Over 300 moves are needed to open this sequential movement puzzle designed by the German Jean Claude Constantin.
Please note that wood colors may vary.

Fun lock, well built for wood. Could be broken if mishandled. No where near a 10 level, maybe 6 or 7. Still fun. Caution, the next words may help you solve this. Don't read if you're going to purchase :-) This puzzle I would consider an n-array type puzzle. That is, a pattern is used in solving. Once you recognize the pattern, the puzzle solve will move quick. Happy puzzling.
Well constructed, fun to play with, just the kind of puzzle I enjoy. Not a level 10 though, but still a worthy addition to my collection.
Was disappointed with this. This definitely isn't a difficulty of 10. I had it solved before the end of my car ride downtown.
the pure definition of procedural , but I wont rate it as a lvl 10 , I got it at first try in less than 5 minutes , lvl 8 or 9 would be more accurate I think.
Amazing, good but took 4 days
Fairly well constructed, though my puzzle did come assembled incorrectly. One of the layers was flipped which made the puzzle unsolvable. Luckily I was able to unscrew the pin and flip the layer around. I'd say this isn't an 8 difficulty. I'd say 5, maybe 6 if you've never done an incremental puzzle like this. There's not really a chance you'll make the wrong move, it's fairly straight forward. Still enjoyable.
