General information

The Puzzle Hunt is a puzzle-solving event where teams of up to 5 people compete to solve as many 'puzzles' as possible. These puzzles will not be like straightforward jigsaws or school/university work. They will not come with any instructions, and the puzzler must use their logical abilities to deduce the steps to take in order to reach the solution.

Eight puzzles are released over the course of four days, with hints released at certain points.

The Cambridge Puzzle Hunt is jointly organized by the Trinity Mathematical Society, the Archimedeans and the Trinity College Science Society. Talks are held on Mondays and Tuesdays respectively every week during Cambridge term time. See websites for more details.
