Cracking Enigma

Welcome to Bletchley Park, 1940 where we have been hard at work trying to crack the German encrypted message system that uses the Enigma Machine. Alan Turing has just shared an amazing breakthrough with you, but the Allied Forces don't believe that you are fully on their side. To prove you work with us at Bletchley Park (if this link doesn't work, try this one) they ask you to break a series of codes that will show them where your loyalties lie.
