Welcome to the 2010 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.
