🔑 The B-Lock - A Clever Step Up

The B stands for Boaz. And like its designer, this lock does not give anything away easily.

The B-Lock looks exactly like a normal padlock. Solid brass, proper weight, standard shackle. But when you try to open it the way you would open any other lock, nothing happens. The solution is hidden inside the mechanism, and finding it requires you to stop assuming and start paying attention.

It is a satisfying step up from our beginner puzzles without being overwhelming. If you have already solved the LoopHole or the FunLock and want something that will keep you busy for a bit longer, the B-Lock is the natural next challenge.

🎁 Who Is This For?

The B-Lock works well as a first puzzle lock for someone who wants a bit more of a challenge than our easiest puzzles, or as a natural progression for someone who has already started their Puzzlocks journey.

It is also a great gift for anyone who loves figuring things out. Solid, well made, and satisfying to solve without taking days to crack.

👥 More Fun With Others

Leave it on the coffee table at your next gathering and watch what happens. The B-Lock is approachable enough that most people will happily spend time with it, and surprising enough that nobody will crack it immediately.

Once you solve it, reset it and hand it to the next person. The reaction when they figure it out is always worth watching.
