Sophie's Safecracking Simulator is a wonderful little experience (is it even a game?) that gives you the opportunity to attempt to break various locks. Created by Sophie Houlden, the same developer who made the brilliant and highly customizable Sophie's Dice.
You've broken locks in all sorts of games, although they're never particularly difficult and usually just involve rotating one thing until it becomes easy as some kind of mini-game, but what about one that teaches you a little about mechanical locks? Sophie's Safecracking Simulator does that and plenty more. There's a wonderful multi-step tutorial to walk you through different pieces of a lock, along with some high-tech tools you can use and you can keep generating a new lock to bust through in record time.
It's genuinely brilliant, do go take a look!
