Rules

Per 17 January 2012 the rules 13, 14, 15 and 16 in the original version of the rules below are replaced by these rules, reflecting the introduction of the new scoring system as explained on the forum:

13. The leaderboard displays the number of chapters solved and the points awarded. For each chapter solved, each team will be ranked in the order in which they solve it.

14. Teams who have solved the most number of chapters appear at the top of the leaderboard. Teams who have solved the same number of chapters are ordered by the total number of points awarded. Further information about how the leaderboard works can be found in our Frequently Asked Questions section of the website.

15. If at the end of the competition winning teams tie on the number of chapters solved and the number of points awarded, then the total time taken to solve the chapters (between the chapters being released and the correct solution being received by our server) will be used to determine the winner.

1. The competition is only open to persons who are in full-time education (including home schoolers) in the United Kingdom in Years 7-11 (in England and Wales); Primary 7, S1-S4 (Scotland); Years 8-12 (Northern Ireland).

2. Entrants must be part of a team. Normally each team should contain no more than 4 people, and the Prize Committee reserves the right to not award prizes to teams containing more than 4 people.

3. Entrants may be part of only one team.

4. Each team and each person within each team ('team members') must register on the website. Each team must choose a name. Offensive or inappropriate team names will not be allowed and we reserve the right to disqualify any team which seeks to use a name which we deem to be offensive and/or inappropriate.

5. Each team must give their School's address and nominate a teacher we can contact. This is so that, for winning teams, we can arrange the prize-giving. Entrants who are home-schooled should provide the name and contact address of a parent or carer.

6. The name of each team will be published on the website. Team members' names will not be published.

7. We may contact teams and team members by email. You will be asked to provide a valid email address when you register for the competition online.

8. The schedule of the codes to be deciphered is

ChapterDate released
19th January 2012
223rd January 2012
36th February 2012
420th February 2012
55th March 2012
619th March 2012
Epilogue2nd April 2012.

We aim to release each chapter at, or slightly after, 4pm on the day of release but the date and/or time of release may vary.

9. Each chapter of the competition contains a code to be deciphered. One word in each code is designated as the 'code word' and it is the code word that should be submitted to the website.

10. For each chapter for which a team submits an entry, the entry will be deemed to be correct if (ignoring capitalisation) it agrees with our solution.

11. An entry will only be deemed valid if it is submitted via the website and it is recorded by our server.

12. The competition closes at midnight on Friday 13th April 2012. Entries made after this will not be counted. The answers will be released on or after Monday 16th April 2012.

Per 17 January 2012 the rules 13, 14, 15 and 16 below are replaced by the rules displayed at the top of this page.

13. The leaderboard displays the number of chapters solved. For each chapter solved, each team will be ranked in the order in which they solve it. (So the first team to solve a given chapter is ranked 1st, the second team to solve a given chapter is ranked 2nd, and so on.)

14. Teams who have solved the most number of chapters appear at the top of the leaderboard. Teams who have solved the same number of chapters are ordered by adding together the rankings for each chapter solved by a team and then listing them in increasing order. Further information about how the leaderboard works can be found in our Frequently Asked Questions section of the website.

15. If at the end of the competition, winning teams tie on the number of chapters solved and the sum of their rankings then a tie-breaker will be used to decide the winner. The tie-breaker is an additional question in the Epilogue to the story. If the tie-breaker is required, then the Prize Committee will consider the submitted solutions to the tie-breaker and will choose a winner.

16. In the event of no correct answers to the tie-breaker being received then the total time taken to solve the chapters (between the chapters being released and the correct solution being received by our server) will be used.


17. The prizes will be awarded by the Prize Committee to the teams that are at the top of the leaderboard when the competition closes. Winners and their schools will be contacted by email. The prizes are kindly sponsored by the flight search company Skyscanner, which was set up by two former University of Manchester based Computer Scientists. The prizes are as follows:
- first place: each team member receives £150 in Amazon gift vouchers
- second place: each team member receives £100 in Amazon gift vouchers
- third place: each team member receives £75 in Amazon gift vouchers.

18. The Prize Committee reserves the right to change any aspect of the competition at short notice. Such changes will be announced on the website as soon as practical.

19. Prize winners agree to their team name and school name being used in publicity associated to the competition, including publication on the competition website. Team member names will only be published with the permission of the team member.

20. In submitting an entry to the website, teams acknowledge that their solution is solely the collective work of the team.

21. Teams who do not abide by the rules will be disqualified from the competition and will not qualify for the prizes.

22. In submitting an entry to the competition, all team members agree to be bound by all the rules of the competition.

23. Rapid fire multiple submissions to the website put an unreasonable load on our website server and could also be evidence of attempts at cheating. Any team who makes an unreasonable number of submissions will be open to disqualification from the competition.

24. The website forum is moderated by the competition organisers. Any misuse of the forum (including, but not limited to, messages that: contain offensive or objectionable material or language, contain personal details (including email addresses), break the law or encourage unlawful behaviour, contain advertising or promotional material, spam) will leave the team member and their team barred from the forum and open to disqualification from the competition.

25. Any team or team member who posts a solution in any public forum will be open to disqualification from the competition.

26. Neither teams nor team members should publish hints without checking with the competition organisers first as this may spoil the competition for others.

27. The competition organisers reserve the right the publish clues and hints on the website and forum as they see fit.

28. Any resemblance in the story to real people, living or dead, is entirely coincidental.
