This complex puzzle box takes some deep thought and patience to crack. It has gears, ciphers, magnets, hidden tools, and other trickery that open multiple hidden compartments.
Ryan Calme built this puzzle box as a gift for his father. Beyond being a tough box to open, the craftsmanship behind it is impressive. I imagine it takes hours to open up, luckily he’s shared the key to open it in this video.
