Well done everyone! As usual a stunning finish, with a number of you successfully completing the challenge trail and quite a few in a very fast time. We will get to the overall winners in a moment, but first I want to thank all of you for making this year's competition the most successful ever. Don't forget to thank your teachers, and tell everyone you know about the contest, because it will be back next year!
We have a few things to announce in the next few days so do keep an eye on the site. There will be details about the Prizegiving, and a teaser for the 2010 National Cipher Challenge. We also have something new to announce. Come back to find out what it is and how to take part!
First the part A winners this week, as usual, each team wins a cheque for £25:
Abi See, Rachel Norris, Martin Rolph, Alastair Janse, Van Rensburg and Declan Corr from Hills Road Sixth Form College
Sid Janota, Liam Breadmore, Sam Mason, Tom Walker, Laura Birks and Helen Birks from Ralph Allen
Kimba from Cedars Upper School
Michael Price, Michael Youssef, Bamboo Panda and Raz from King Edwards School Edgbaston
Bryony Richards from South Wilts Grammer School
Ruth and Sophie from King Edward VI High School For Girls

Laura Bowlby and Lynn Zheng from Oxford High School
Now here are the details of the overall winners:
The GCHQ prize of £1,000 is awarded to Jolyon Warren from Fernwood Comprehensive. He submitted in just over half an hour, which was an incredible time for this tricky Jefferson Cipher (or should that be cypher?) we set in 8B
The team "Ready Steady Meady" from King Edward VI School win the IBM Prize which this year consists of five iPod Touches (one for each team member).
The Trinity College Prize of £700 is awarded to David Edey from Alcester Grammar School.
There were so many excellent submissions this year it seems unfair to pick out just a few, but we have to and congratulations to these winners this year.
All the best, Harry
