Today I’ll try to solve the rare Popplock T12. This is a custom-made puzzle lock made in Germany by the legendary designer Rainer Popp. The goal is to unlock the lock, which will require 10 steps. One of the craziest puzzles we had on this channel so far!
More information about the Popplocks here.
I enjoyed solving this puzzle so much that I decided to make an explanation video breaking down its mechanisms.
Enjoy!
