Crack the secrets of hidden messages in this hands-on workshop all about codes and ciphers.
About this Event

In this workshop participants will work like real codebreakers, exploring how people have kept information secret for thousands of years—from ancient ciphers to modern techniques developed in the last 50 years. Through puzzles and challenges, they’ll discover different ways messages can be disguised, scrambled and protected.

By the end of the workshop you'll learn the tools and techniques needed to decode messages such as 14010901070822112008280903102110110223112612, VMGLTJGSFTQWKXQUGS, or even strings of binary code.

Covering a range of decoding methods, participants will create their own secret messages to challenge others.

Perfect for curious minds, this workshop is all about problem-solving, pattern-spotting and thinking like a true codebreaker.

For children who have just completed Years 5 and 6 this term - please book based on your child’s current/most recent school year, not their new year group from September. This typically corresponds to children aged around 9–11 years old. We reserve the right to refund or deny entry to those who are not in the correct year group.

Refunds can only be issued for tickets cancelled at least two weeks (14 calendar days) in advance of the event date. Please note that this supersedes our normal event terms and conditions.
