Communications and code-breaking

To mark the centenary of Alan Turing's birth, join the UK Government Communications Headquarters (GCHQ) for interactive games and puzzles to test your problem-solving abilities.

Turing, who worked at GCHQ's predecessor, the Government Code & Cypher School, is credited with designing the 'Bombe', a machine that helped decipher German Enigma signals at Bletchley Park during the Second World War.

This is your opportunity to get your hands on a genuine WWII Enigma - use it to send a secret message to Bletchley Park and then watch via webcam as code-breakers at Bletchley try to decipher your message.

There will also be three challenging games where you have to answer questions, break codes and solve logic puzzles in order to find secret messages, prevent a cyber attack on the UK, or break into a safe to find a prize!
