Visual Description

B-Lock II is a spiritual successor of B-Lock and Danlock puzzles. Created by Boaz Feldman, B-Lock 2 is a bit harder than it’s predecessor and will keep you wondering and scratching your head for a while.

Looks like a simple lock with a key, but it cannot be opened without a few neat little tricks.

Of course, if you have previously tried your luck with either Danlock or B-lock I — you will probably be able to guess what should be done quicker, but then again — all the tricks might resemble the previous lock puzzle, but still have some unique fleur and style to them.

The craftsmanship is great, the quality of the lock and the key is superb.

Main Features

The best thing about this lock puzzle is that you only have a key to operate with. Quick spoiler: there are not secret compartments, tricky pins hidden somewhere or anything like that: all you need is the key to open the lock. Sounds quite obvious and simple, right?

The mechanism inside the lock, on the other side, is amazingly crafted. There is absolutely not force needed to open this lock as well, so make sure not force any of the movements through to avoid braking the key.

Lastly, this can be used as a real lock! I mean, you can definitely hang it on some kind of locker or a chest. Even if someone obtains the key from it — they will never be able to open the lock without knowing the trick. Isn’t that amazing?
