CiSRA Puzzle Competition
Welcome to the CiSRA Puzzle Competition web site. The puzzles here have an unusual twist: no instructions are provided, and each puzzle works differently. The competition ran annually from 2007 to 2013, but has now ended. You can browse the puzzles and results of the competitions in the competition archive.
For people interested in the types of puzzles we produced, the following are similar competitions (not run or endorsed by CiSRA):
- MUMS Puzzle Hunt - run by the Melbourne University Mathematics and Statistics Society.
- SUMS Puzzle Hunt - run by the Sydney University Mathematics Society.
- mezzacotta Puzzle Competition - run by several of the people who created puzzles for the CiSRA Competition.
CiSRA is Canon Information Systems Research Australia, a leading research and development centre for Canon.
