The National Cipher Challenge

And on to the next …

We offer sincere congratulations to all of you in making it this far. 748 teams are still with us at the end of Challenge 6B and fighting hard to compete! Things will get a little harder this week, and after that the gloves are off; we are really looking forward to seeing how you get on.

We have 9143 participants registered for the competition which is close to the record! We always have a few signing up to take part in the last Challenge and we are intrigued to see if we can break that record this year. It might be a bit late to hope to win prizes, but leaderboard positions (and certificates) for each round are still up for grabs, so encourage your friends to get involved.
