B-Lock is an original lock puzzle designed by Boaz Feldman (the son of Dan Feldman, the designer of the DanLock).
B-Lock is a two-stage puzzle. Upon the first examination, you'll notice that you can't actually insert the key into the keyhole... It's BLOCKed! To unlock it, you'll really need to think outside the box. The specific trick of this lock puzzle is like nothing you've seen before. A Eureka moment is promised for the solver.
