  • Prime Number Challenge

    The series and the main Code Challenge begin in late July but you can get involved now by taking photos of prime numbers you spot in the world around you. Post them on our Facebook wall or tweet them to @bbccode (links for both on right). Alternatively, tag them 'bbccode' on your photo sharing website of choice.

    Once we have the first 100 primes captured we'll release a clue to get you all a little bit closer to cracking the Code Challenge. A further clue will be released after 200 primes and a final clue after 300.

    By submitting your photos, you agree to allow us to share them on our Facebook page and our blog.
