The National Cipher Challenge

Today’s the day!

In particular it is the day we start the competition, though as I keep reminding you, the first three challenges are for practice, so you don’t need to panic if you miss any of them or are slow to break them! Sharpen your pencils and your brains, and come back at 3pm to see how the story begins.

You have until 23:00 on Monday 13th Oct to get full marks on this first challenge, so if you are not free at 3 today it really doesn’t matter. Indeed, you might find it easier to wait at least a few minutes before checking the challenge as the site is often very busy at the start of each round.

We hope you enjoy it!
