CiSRA Puzzle Competition 2009
This is the archive of the 2009 Puzzle Competition. Please visit the current competition site for information about the latest Puzzle Competition.
Welcome to the 2009 CiSRA Puzzle Competition web site. The puzzles here have an unusual twist: no instructions are provided, and each puzzle works differently. New puzzlers may wish to consult our puzzle solving guide and warm up with puzzles from previous years before registering for our annual competition. Entry is free. Australian students can win prizes (terms and conditions apply).
CiSRA is Canon Information Systems Research Australia, a leading research and development centre for Canon.
