National Cipher Challenge 2019

I and Will Bywater took part in the National Cipher Challenge 2019, despite managing to complete all challenges including the final hardest challenge 9B (took 16 hours!) unfortunately we did not win the competition however it was a rewarding experience and we gained a lot from it.

Some of our workings from challenge 9B, you had to shift the right hand green lines going parallel across the page to make them vertical which we could then decode to get the final message.
