Welcome to the National Cipher Challenge, a nationwide, online codebreaking competition, which will run from October 13th 2016 to January 4th 2017. We will open for online registration on October 3rd.
The competition is a great extension activity (or a fantastic maths club project) that can be tackled by students in teams or on their own. There is no charge to register or take part, and all you need to get involved is a reasonably modern web browser.
The competition has been running since 2002, and regularly attracts entries from teams at over 700 UK schools and colleges. Long time competitor, Julian Bhardwaj, said of the Challenge
