Clues for Ritangle 2018
The correct answer to each of questions 1 to 25 releases a particular clue for the final question.
Please collect your clues carefully without sharing them with anyone outside your team. In addition, make a note of your final answers for the first 25 questions, because you will need them again later.
Once you have registered your team (complete the form and submit your registration using the 'Register your team' button) you may submit an answer to the preliminary round below. The captain's e-mail address is required again so we can check your team has been registered.
The answer to the preliminary round is a string of 18 digits. The first two digits of this string are the position in the alphabet of the answer to preliminary question A. The other 16 digits are as described in preliminary questions B to E.
When you submit an answer an e-mail will be sent to both the team captain and the nominating teacher. For correct answers this will contain a clue for the main competition. If your answer is incorrect then you can try again. You don't need the clue to solve the main competition.
Keep your answers safe for now (and don't share with other teams!), see above for details of how correct answers to these questions unlock clues for the final question.
