  1. This is an individual event.
  2. All problems will require mathematical reasoning and will be reducible to a simple method with which the answer can be computed. We assume the use of computers even though most of the problems can also be solved on pen & paper with little more effort.
  3. Answers to all the problems will necessarily be a non-negative integer with no trailing zeros. Answer will not contain a decimal point or any other special character. Integers will contain no more than 3200 digits in all cases.
  4. There are 8 levels, containing 5 questions each. Level 0 is initially unlocked. To unlock Level 1, you need to solve at least 3 problems of Level 0. To unlock Level 2 and subsequent levels, you need to solve 6 problems out of 10 from previous two levels.
  5. There has to be a gap of at least 2 minutes between two consecutive submissions of the same problem.
  6. Each problem has equal weightage. Though there is no time penalty, tie-breaking will be done by the time of last successful submission.
  7. For any doubts/queries you can post comments, which will be moderated.
  8. Hints (if any) for a particular question will be released through comments by Admin.
  9. If you are facing any issues, you can contact us at gordianknot@felicity.iiit.ac.in.
