Visual Description

“Lock’d In” Puzzle Lock is one of the few products (you might know their spinners) by Grave Raven.

I’ve tried to find some more info about Grave Raven on their website, Facebook account, Google, but the only thing I found out is that the designer’s name is Bryan Turner. It seems like the company likes to puzzle people indeed 🙂

Main Features

The puzzle itself looks like – wait for it – a lock! Nothing more. There is a slight engraving in the front and in the back. It comes in different colors, depending on the material. You’ll see there three options:

  • Brass (gold color)
  • Alumnum (silver color)
  • Stainless steel (silver color)

So you’re holding a simple looking thing you need to unlock. No buttons, no key-holes, triggers or anything that can give you a hint. Just an unobtrusive clang, that changes a little depending on how you shake the lock. Please try not to get annoyed by the sound.

The thing I always pay attention to is the packaging. Here we have a nice small matt black box with shiny little blue details. Inside of it there’s a card with the signature of the manufacturer.

The price differs depending on material.

Simplicity is the ultimate sophistication. If you agree with that, you’ll love the puzzle.

The manufacturer states it will take you 10 mins to solve it, but hey let’s not flatter ourselves – it can take much more 🙂

Important Notes

Tips and Tricks

Spoiler alert!

Inside the lock there’s a gear-shaped hole with a smaller gear. There’s also a notch in it and a stick and needs to be trapped in it. Now do this:

  1. Shake it so that the stick gets stuck in the notch.
  2. You’ll feel and hear that it’s trapped so just slide it and open!
