Overall Winners
Posted by Sebastian on Wednesday 10th April at 11:29 am.
Dear All,

Thank you to all cryptographers for taking part in the competition this year. We hope you have enjoyed this year's competition as much as we have enjoyed designing the clues and watching your progress via the competition forum.

You will all have seen the leaderboard since the final chapter, so the overall winners will come as no surprise, but we can now confirm that the winners of the 2013 Alan Turing Cryptography Competition are:

First Place: G15

Second Place: Room40

Third Place: SmileyFaces:)

Congratulations to the 3 winning teams and also to the 46 other teams who have completed all 6 chapters. The pizes and trophies for the winning teams, as well as certificates for all teams who completed the 6 chapters, will be dispatched to your designated teachers next week.

We very much hope to run the competition again in 2014 and details will be sent to your School later this year.

Good luck to anyone currently studying for their exams, have a great summer and we hope to see you all back in the competition next year!

Closing dates of the Competition and the website/forum
Posted by Kees on Tuesday 2nd April at 7:45 pm, last edited by Kees on Tuesday 2nd April at 7:46 pm.
Dear all,

we are gradually reaching the end of the competition. . Indeed all chapters have now been released, including the Epilogue, and as you can read in the FAQ the competition closes

at midnight on Friday 5th April 2013.

This means you can submit your solutions and earn points for the leaderboard until that moment. After that moment the site will still be active and the forums will remain open until

Tuesday 30th April.

After that day it won't be possible to log in anymore and the site will go into 'static mode'.

We very much hope you have enjoyed the competition . We are very happy to hear your thoughts in this topic.
Third Hint for Chapter 6
Posted by Sebastian on Wednesday 27th March at 4:01 pm.
The spacing of the white teeth on the control disk is such that the alphabets can move 3, 4 or 6 spaces relative to one another (not necessarily in that order). If you don't want to write a computer program and even if you do, the easiest way to try all possibilities is to make your own machine using paper, cardboard, sticky-backed plastic and a split pin.

There are a lot of possibilities to try, but many can be discarded quickly (once they stop making sense). I have a feeling that Barquith would probably have chosen a starting position that puts A somewhere near the middle of the alphabet...
Chapter 5 Prize Winners
Posted by Sebastian on Wednesday 27th March at 2:33 pm.
Congratulations to Ronathonasaurus, who have won the prize for solving Chapter 5 in the fastest time.

The spot-prize winners for chapter 5 are:

QED
Rob420
$partacus
SAFE-CB's
DiDiWiN?

Congratulations to all teams. Your prizes have been dispatched to your designated teachers.
Bonus Code in Epilogue
Posted by Sebastian on Monday 25th March at 4:03 pm.
The epilogue to the story will be released at 4pm next Monday (1st April).

The epilogue will contain a bonus code - there won't be any points or prizes available for it, it's just for fun!

Good luck

Second Hint for Chapter 6
Posted by Sebastian on Monday 25th March at 4:01 pm.
For each letter of the message, the central wheel is moved until the next white tooth on the control disk hits the stop.

This means that the two alphabets (one on the wheel, one on the ring) move a certain number of places relative to one another. This changes the substitution cipher for each letter in the message. You need to work out the spacing between each white tooth on the control disk to determine how many places the alphabet moves each time.

You also need to find the starting position of both the central disk and the control cog that decodes the message ....

Don't forget that in the classical Latin alphabet a V can stand for a U or a V!
Hint for Chapter 6
Posted by Kees on Thursday 21st March at 5:30 pm.
The reconstructed control disk appears in chapters 1, 2 and 4; and more details about the machine can be found if you decipher the complete message in chapter 5. Haworth's sketch does NOT show the correct starting position of the machine ... there are 69 different possibilities!
Hint for Chapter 6 will be released tomorrow.
Posted by Andrew on Wednesday 20th March at 4:31 pm.
We're aware that a number of people are stuck and would *really* like a hint. That said, we want to be fair to those teams that have solved the chapter without a hint, so we are going to wait until the prize-winning places can no longer be affected. That means that the first hint will be released on Thursday 21st March at 5:30pm.

Good luck to those still battling...
Chapter 6 Problems Fixed
Posted by Sebastian on Monday 18th March at 5:35 pm.
Dear All,

The problem affecting Chapter 6 has now been resolved and you can submit your answers. Anyone who had previously attempted to submit an answer and was re-directed to an external webpage will not have this counted as one of their 3 attempts.

This issue may have caused problems in regards to the winner of the prize for solving the chapter in the fastest time. We will have a further look at this and will advise accordingly.

Our apologies for any inconvenience this issue has caused and good luck with the clue!

Problems Submitting Answers to Chapter 6
Posted by Sebastian on Monday 18th March at 4:48 pm.
Dear All,

We are aware of a problem in submitting answers for chapter 6. We are working on resolving this and the system will be back up and running ASAP.

Our apologies for any inconvenience.

Final Hint for Chapter 5
Posted by Sebastian on Wednesday 13th March at 4:09 pm.
Did you know that hieroglyphics can be read forward and backwards depending on the direction of the symbols? Another fascinating hieroglyph fact is that a cartouche surrounds a name, in this case one of the characters in the story.

Oh, one more thing, each symbol stands for one letter, but there is more than one symbol for each letter ....
Chapter 4 Prize Winners
Posted by Sebastian on Tuesday 12th March at 2:55 pm.
Congratulations to the team 'Wellensis' who have won the prize for solving chapter 4 in the fastest time.

The five spot-prize winners for chapter 4 are:

CJFC
WeEat3.14159
pie3
WinterPonies
Bletchley_Shark

Congratulations to all the above teams and good luck for the remaining chapters!

Chapter 5 - Second Hint
Posted by Sebastian on Monday 11th March at 4:40 pm.
Hmmm, there appear to be more symbols than letters in the alphabet, but maybe there's some rule that links each symbol to a letter.
Chapter 5 Hint
Posted by Sebastian on Wednesday 6th March at 4:09 pm.
Try looking up the significance of the cartouche ...
Chapter 5 Hints
Posted by Sebastian on Wednesday 6th March at 11:19 am.
Congratulations to those who have so far solved chapter 5, we were very impressed with the speed of the first team to solve.

To help those of you who are still working on the chapter, we will release a brief hint at 4pm today (Wednesday 6th March) and another will follow on Monday 11th at 4pm.

Good luck!
Chapter 5
Posted by Sebastian on Monday 4th March at 4:00 pm.
Good luck to all cryptographers, Chapter 5 is now released!
Chapter3 Prize Winners
Posted by Sebastian on Thursday 28th February at 10:20 am.

The winners of the spot-prizes are the teams:

IGSSBand(B)
AlphaOmega3
Hippos_United
Teamsheep

All the vouchers will be posted by the end of this week. Congratulations to all winners and do keep solving the clues, there are several more prizes up for grabs...
Chapter 4 - second hint
Posted by Charles on Monday 25th February at 4:03 pm.
Mr B left the code behind Moseley's table - is Moseley's work connected with another table?
Chapter 4 Hint
Posted by Sebastian on Wednesday 20th February at 4:56 pm.
Where exactly did Mr B leave the code - maybe there's a clue in that?
Unclaimed Prizes
Posted by Sebastian on Friday 15th February at 2:17 pm.
The competition closes at midnight on Friday 5th April. Any unclaimed chapter prizes will be available for the relevant teams to claim up until the release of the Epilogue (4pm on Monday 1st May).

Any prizes remaining unclaimed at this time will be withdrawn or redistributed at the discretion of the competition organisers.
Chapter 2 Prize Winners
Posted by Sebastian on Friday 15th February at 9:49 am, last edited by Kees on Tuesday 26th February at 8:46 pm.
Congratulations to the team 'KnightsRadiant', who have won the prize for solving chapter 2 in the fastest time. That's 2 different winners for 2 chapters - maybe a few other teams can make it 6 in 6...

2 teams, 'Everlark' and 'quicksilver', have so far been sent spot-prizes for chapter 2. Congratulations to these teams. And do remember, there are 5 spot-prizes available for each chapter.

The spot-prizes for each chapter are drawn shortly after each subsequent chapter is released. However, before we are able to dispatch the prizes, we need to confirm a few details with the teachers each team listed at registration. At present, we are still waiting for responses from the teachers of 3 teams and are therefore unable to dispatch these prizes.

The 3 further provissional spot-prize winners drawn for chapter 2 were:

JOROCODES
stmarys
Mathmos

Any members of these teams should speak to their registered teachers and ask them to contact us.
Multiple Team Registrations - Amnesty
Posted by Sebastian on Tuesday 12th February at 11:00 am.
Dear Cryptographers,

It has become apparent that some individuals are registered to more than one team for the competition. This may be because they were unable to have all friends on one team, or perhaps because it is thought multiple teams would increase the chances of winning a spot prize.

Rule 3 clearly states that entrants may be part of only one team. We will shortly be looking at all registrations for the competition, with a particular emphasis on looking for multiple registrations. All competitors found to be registered to more than one competing team (as well as their team mates) may be penalised accordingly.

However, before this happens, we will be holding a brief amnesty for anyone who would like to take this opportunity to cancel any extra registrations. Any cryptographer who emails us before 4pm on Monday 18th February, noting the team name and username of any registrations they would like deleted, will face no further action.

Anyone found to be registered to more than one team after this time will be subject to further penalties, to be decided on a case by case basis.

Points Deduction - Team QED
Posted by Sebastian on Tuesday 12th February at 10:13 am.
Dear All,

It had been drawn to our attention that the team QED had been collaborating on the answers to the cryptographic clues with someone registered to another team, 'pattisons-y11'. After investigating this matter we discovered that the teams had been working together at the suggestion of their teacher.

However, regardless of the reasons for why teams collaborate, such actions are a breach of the rules and teams will be penalised accordingly. We have, therefore, deducted 2 points from the chapter 3 score of team QED.

Chapter 3 hint
Posted by Sebastian on Monday 11th February at 4:04 pm.
It looks like a substitution cipher. Frequency analysis might help, as might looking for commonly occurring 1-letter or 3-letter words.
Also, the last line looks like a signature - it's probably the name of a character who has already appeared in the story...
Chapter 3
Posted by Sebastian on Monday 4th February at 4:04 pm.
Chapter 3 has just been released. Good luck to all cryptographers...
Chapter 3
Posted by Sebastian on Friday 1st February at 2:52 pm.
Don't forget that chapter 3 will be released at 4pm on Monday. The competition gets harder as we go along, so don't despair if the answers take a little longer to discover in the later chapters!
Chapter 2 - Hint
Posted by Sebastian on Monday 28th January at 4:03 pm, last edited by Sebastian on Monday 28th January at 4:04 pm.
Some of the letters look a bit different, maybe there is a message hidden there?
Next Chapter to be released tomorrow, Mon 21st Jan at 4 pm
Posted by Kees on Sunday 20th January at 2:02 pm.
We are now two weeks underway in the competition, with currently a total of 699 activated team accounts and 1391 activated team members! It is great there is again so much interest in the competition. Furthermore 427 teams have found the correct solution to the first Chapter, well done! .

Tomorrow, Monday 21st Jan, Chapter 2 will be released at 4 pm. Good luck with that one!!

Don't forget you can still register a new team for the competition (or join an existing team) if you haven't yet done so via the registration page.
First Chapter to be released coming Monday 7th January at 4 pm!
Posted by Kees on Sunday 6th January at 8:40 am.
Welcome on the now fully functional website of the 2013 edition of the Alan Turing Cryptography Competition!

If you participated last year as well you are already familiar with the main elements of this site, and otherwise you might want to have a look around. On the page you are currently reading you will regularly find new news items. Furthermore there is a team notepad where you can privately exchange notes with your team mates and there is a forum where you can talk to members of the other teams and to us. 'Us' is the organisers of the competition, on the forum we post under the team name 'CryptoTeam' with users Helen, Sebastian, Charles, Andrew and Kees. If you have any questions or problems throughout this competition (and you can't find the answer in the FAQ for instance) you can get in touch with us on the forum, or via email: cryptography_competition@manchester.ac.uk.

In the left menu you find the six Chapters that together make up the 'Tale of the Egyptian Enigma', a new adventure for Mike and Ellie and at the end of each Chapter a puzzle for you to solve and to earn points with! These Chapters will be released fortnightly, starting coming Monday 7th January at 4pm.

We wish all of you a lot of success and fun, and we hope the competition will be as nice as it was last year!
This competition is organised by and sponsored by
