This is the thirty-fourth instalment of the Fortnightly Topic Challenge described here, with topics suggested and voted on here. This fortnight's topic is safes and locks(suggested by BmyGuest), and will span from the the 31st of July to the 13th of August. During this period, we will compile the list of questions with this tag and post it as an answer to this question.
In the meantime, please go and propose and vote on future challenges!
Everyone have fun, and happy puzzling!

For those that cannot see the deleted answer suggestion, here is how it was described:
How about safes or locks? (Maybe a better tag name would be required, but I can't think of one right now.)
These would be all sorts of puzzles which could be used in role-playing-games or similar as 'obstacles' for the players. While any puzzle might be framed to be a 'safes & locks' puzzle, I'm really thinking of puzzles which are simple and not too multi-layered, which have a simple visual representation, and which could be used 'out of the box'...
Edit: Not patient enough to wait for the challenge to be selected one day... so I posted an example puzzle right away :c)
