An intriguing wooden lock that needs no key to open. There are four sliders that move horizontally, but they can’t move freely. You’ll need to move them in a sequential order and, as the name suggests, you need to do a minimum of 250 moves to open the lock. Invented by the prolific puzzle designer Jean Claude Constantin.

I was expecting something a little more challenging, I was a little dissappointed when I solved it in less then 15 minutes but still, I can appreciate the craft. Great quality and great looking. The solution to this puzzle is quite calming.

My wife gifted this puzzle for my birthday (I requested it!)
There is no much to say, it is fantastic and perfect if you like logic puzzles, n-ary puzzles. But be aware because you can lose track of what step you are taking and just slow doing with your solving process and you will eventually open the lock! Fun, fun fun!

Constantin puzzles are always great in many ways: quality, durability and challenge.
the Schloss 250 is not that challenging for my brain, but I absolutely love it. Definitely recommended to any collector.
