Congratulations to everyone. It has been the best challenge ever, and we have really appreciated all the effort that everyone has put in. The forums have been livelier than ever , and special thanks are owed to Smaug and his dragonlettes for all their efforts.
Of course what you want to know is, "who has won?".
First place, and the GCHQ prize of £1,000 goes to The Enigmas from Harrogate Grammar School. With exactly one, perfect submission for each Challenge they showed how it could be done with great style.
If you are waiting to hear who won this year's competition, you will have to wait a little longer! Even thought the deadline for submissions is midnight January 1st, we do have to convene the prize committee before we can make a decision. Announcements will be made early next week. So carry on biting those nails, chewing those cushions, and posting those whithering, "what on earth is Harry up to?" comments til then. Happy New Year,
I have set up a small list of books, dvds and cds at Amazon that you may like. They are not all related to codes and ciphers. There are some good general interest maths books, and some great adventure stories too, many of which have inspired us in writing past challenges. Anyway feel free to use or ignore the list.

Congratulations to the following winners of prizes for Challenge 7A:
The book prize goes to The King's School, Grantham, for the magnificent efforts of Adin Samson, Jack Smith and Richard Whitfield.
The following teams will each win a £25 cheque:
Laura Plant, Rachel Harrison, Emily Davies, Rachael Bowes and Jon Wozniak from Cheadle High School
The three main prizewinning teams will be invited to a celebration lunch at Bletchley Park as part of the prizegiving ceremony on the afternoon of Friday 27th March. The afternoon will include a lecture by Marcus du Sautoy, author, broadcaster, mathematician and newly elected Professor of Understanding of Science at Oxford. Mark Urban, Newsnight editor, presenter, and author of the biography of George Scovell (on which this year's challenge was based) also hopes to be able to attend.
Here you will find the points scheme for Challenge 8B. As usual we will combine the marks you get on each of the part B challenges to give a final ranking for the competition. We will then select the three winning teams from those with the highest score overall, ranking these winners 1st 2nd 3rd using the overall scores. If there is a tie for first or second place we will use the actual time of submission for the 8B challenge to decide which team takes precedence.
We hope that you will crack Challenge 8B without further help from us, but we may well give out hints to help, especially if you are all struggling! So do keep an eye on this page, and read the forums regularly to see any replies we give.
Good luck to all of you. By the way, this last challenge carries a lot of marks and it is quite possible that the final winner will come from lower down the rankings at the end of round 7, so work at it.
Here is the points scheme for Challenge 8B:
Well done for everyone who had a go at Challenge 6B the padding and the extra characters really made it tough. Anyway, here are the winners for the part A prizes in that round:
1. The Chadster and fogmike from Judd
The points schedule for Challenge 7 is as follows:
20/11/08 15:15 20/11/08 20:00 54 points
Owing to a misunderstanding between Mr. Php and Prof. MySQL the leader boards we published earlier today were not entirely consonant with the actualite. The confusion arose because Mr. Php forgot to tell us that he didn't put his clock back to GMT last weekend, so anyone who submitted their solution within an hour of a deadline was treated as missing it. Luckily Prof. MySQL agreed to mark everyone's work again, and we have now published new leader boards. As a result there are actually 20 teams in joint first place on the overall Leader Board, not the 15 we advertised earlier.
Well done to everyone who cracked Challenges 5A and 5B, this was a tough round and the top of the overall leaderboard shows it. We are down to just 16 sharing top honours for the competition. Of course if they all slip up there is still room for people lower down to steal the title.
Anyway, here are the winners of the Challenge 5A prizes:
The book prize goes to Chatham Grammar School For Boys for the efforts of Short Stuff, (Cryptus, Zacsafus, Mr Biggles and Banksy), while the following teams each win one of the £25 cheques:
Kolobok from Dame Alice Owen's School
