Welcome to the National Cipher Challenge 2015. Registration begins on 5th October 2015, though you might find you can register from 30th September while we warm up the website!
This year's competition centres on my adventures in post war Berlin. Join me in tracking down the Reichsdoktor by helping me to crack the enemy's codes and ciphers.
The first Challenge will go live at 3.15pm on Thursday 15th October, so you have plenty of time to prepare. You can find some notes on codebreaking somewhere on the website (you thought we would make this easy for you?) and there is a forum where you can discuss the Challenge.
Looking forward to hearing from you,
