Welcome to the ΣUMS Puzzle Hunt home page!

This year's hunt commenced on the 2nd of November.

Registration is now open.

Having finally accrued enough puzzles since the thrilling 2014 hunt, ΣUMS is back with what we hope to be an even better puzzle contest in 2015!

The ΣUMS Puzzle Hunt was created to encourage people to employ mathematical thinking without having to understand any maths. The puzzles are designed to not require any specialist knowledge and so should be quite accessible for everyone.

Our puzzles range in style from picture and word puzzles, to logic and cryptic puzzles, and everything in between. To get an idea of what to expect, check out the puzzles from our previous puzzle hunts.

This year the hunt kicks off on 2 November, noon AEDT. Be sure to check the rules and FAQ for more information.
