Puzzle Hunt Rules
Please note that the rules shown in bold have been updated.


  • To find a hidden object specified in the puzzles.
  • Gain as many points as possible by solving the puzzles using the least number of hints.


  • Each team can have a maximum of 10 members. Each member must provide a valid email address.
  • There is no other restriction on teams; in particular members do not need to have an association with the University of Melbourne or reside in Australia.
  • A team may use any source of information, including the internet and other people.
  • Any action deemed unsportsmanlike by the Puzzle Hunt organisers may result in disqualification. This includes, but is not limited to, contravening these rules, soliciting for answers or hints from the MUMS Committee or anyone involved in organising the Puzzle Hunt, stalking the MUMS Committee or other teams.
  • MUMS Committee members may not take part in the Puzzle Hunt.


  • A set of puzzles will be released at midday on each day from Monday 27 March to Friday 31 March. There will be five such sets in total.
  • At midday after the day a puzzle is released, a hint for that puzzle will be given out. The day after a second hint will be released, and a third hint on the day after that.
  • Puzzles and hints will be posted on the puzzles page of this site. Teams will be notified by email when they are released.
  • Answers to puzzles are to be submitted online.
  • Guesses across all puzzles are limited to 100 per day. Guesses will only be deducted for incorrect attempts.
  • You may submit answers to any puzzle from the time of its release until the end of the hunt.
  • In addition to the puzzles mentioned above, a special "meta" puzzle will be released along with the fifth set of puzzles. The metapuzzle ties in all the clues from the previous puzzles to reveal where the hidden object is located. Note that you will need to have solved most, if not all, of the other puzzles in order to be able to fully solve the metapuzzle.
  • There will be 20 puzzles in total, 4 on each day. Teams should find that this year's puzzles will not eat up as much time as last year's.
  • Solutions for all puzzles will be published upon completion of the hunt.


  • The team which recovers the object will be awarded the major prize.
  • Second and third prizes will be awarded based on score.
  • Upon solving a puzzle, a team receives the number of points it is currently worth.
  • Each puzzle is initially worth 5 points. For each hint we give out for a puzzle, a point will be deducted from its value, down to a minimum of 2 points.
  • Scoring stops when a team recovers the hidden object and returns it to the Puzzle Hunt organisers in the MUMS Room.
  • In the event of a tie in score, teams will be ranked by the number of puzzles they have solved. If there is still a tie, then ranking is by the time of their latest solved puzzle (earliest first).
  • Teams will be able to view their progress and also that of other teams via the Puzzle Hunt website.


  • The team which recovers the object will receive $200.
  • The highest ranked non-winning team will receive $100.
  • The second highest ranked non-winning team will receive $50.
  • Winners will be announced via email.
