Well, now everybody knows about The Game.
For the last few weeks I've been playing this game with people in PGP Club:
Level 1 is decrypting a message.
Level 2 is encrypting a message to me.
Level 3 is verifying a signed message.
Level 4 is signing a message.
Some people don't get it, most do. A few are quite proud of their achievement

A few got to Level 3. Only one person got to Level 4 and he wasn't a newb, just did for the lulz.
We brainstormed that Level 5 could be verifying a binary signature like for the browser bundle or Tails ISO (useful to know how to do), and there could be other levels.
I'd like to turn the game into a web app on a hidden service that people could play with, but I don't know PHP or JavaScript.
