Ritangle is a competition for teams of students of A level Mathematics, Scottish Highers or the International Baccalaureate
No knowledge of mathematics beyond A level Mathematics required
For the main competition, one question is released daily for 21 consecutive weekdays. The first question was released on 9th November 2017.
The final question unlocks an overall answer based on the solutions to all the questions
A maths hamper prize, including a free year long subscription to Integral, and trophy for the school or college of the winning team!
Technology can help with some Ritangle questions
Hints for question 21
We'll post any hints for question 21 here on weekdays at 0900 up until the end of the competition on 13th December.
Main Competition Questions
The answers to questions 1 to 20 are used to answer question 21.
To do this, each of your answers to questions 1 to 20 should be spelt out as text, so the answer 123 would read
onehundredandtwentythree.
You only need the first 20 characters, for example
onehundredandtwentyt.
The answers to questions 1 to 20 should then be arranged in grid form.
You do not need to solve every question to find the overall answer to Ritangle. Where there are gaps, you may be able to guess sensibly.
You will be able to submit your overall answer to Ritangle from 0900 on 7th December, when question 21 will be released and registration will close.
The five preliminary questions
We would like to clarify that, in Preliminary question A, a self-descriptive number needn't have exactly 7 digits. We have slightly altered the question shown here from the version originally released to help clarify this.
The answers to the preliminary questions combine to give a string of 17 characters.
Registered teams can now submit their answer to this.
A correct submission returns a clue for the main competition by email.
