Congratulations to everyone who has got this far. Challenge 7 was a bit of a beast, but Challenge 8 will be tougher. We will be publishing parts of the key as time goes by so even if you get really stuck you should be able to crack the cipher by the end of the competition on January 9th. To let you try your skills we will leave hints until Christmas. By then we suspect the winners will have cracked it anyway, but who knows! Anyway the first part of the key will be published on Christmas Day and then we will publish a letter a day for a while.
In the meantime each of the following 8 teams have win a cheque for £25 for their entry in Challenge 7. We will be in touch by email to the address you gave us when registering, but not until early the New Year so do please check your email then and get back to us promptly so we can process your award.
To everyone else, good luck with the final challenge of NCC2013. All the best,

Big apologies for those of you who had trouble logging in last night. The fault was traced to an update/hint to the challenge page, which was designed to make it easier to crack. Unfortunately , in the process we made it impossible to submit. We have amended the scoring system so that no-one will be disadvantaged. Please accept our apologies again,
Weren't you listening? I said "bifid"!
If you want a clue (part of the polybius square) - see the Challenge page.
Good luck, Harry
Challenge 7 already? It doesn't seem possible. You have two weeks for this one and I think you will need them. If you have been following along you should have an idea what type of cipher has been used in 7B, if not take a look at Challenges 6A and 7A. Challenge 6B has some useful information in it as well, but I am being deliberately vague at this point. On Monday we will publish the name of the type of cipher used, in case you haven't managed to figure it out. Next Thursday we will publish some notes/hints on how to tackle it, giving you a week to have a go if you are still completely stuck. After that we will gradually reveal parts of the key to the cipher to get you started. Of course that will still leave Challenge 8 to do over Christmas and we will follow a similar pattern with that. The more you can manage on your own the faster you will be and the more points you will get, so don't wait for hints. If you are stuck follow Turing's advice: Do Something! It doesnt really matter what - count letter frequencies, look for patterns, hunt for cribs or research ciphers on the web. Anything beats nothing.
Each of the following 8 teams will win a cheque for £25. We will be in touch by email to the address you gave us when registering, so do please check it and get back to us promptly so we can process your award.
To everyone else, for one more episode at least, there is always next time. Good luck,
