Following on from the huge success that was their inaugural competition earlier this year, mathematicians from the University of Manchester have put together another Cryptography Competition in honour of father of modern everything, Alan Turing.
This time, the competition is open to teams of school children from all over the UK, and comprises a six-chapter story featuring
Alice and Bob Mike and Ellie, who get “caught up in a cryptographic adventure”. Solving all the puzzles and cracking the codes faster than other people gets you on the leader board, and there are prizes for being near the top as well as extra prizes for randomly-selected teams who’ve solved everything. (You know that since it’s a maths department, their randomisation algorithms will be top-notch). It’s also possible to enter as a non-schoolchild, and check your answers on the site, although you won’t be eligible for prizes. The competition is aimed at UK school years 7-11 (age 11-16), although I can confirm it’s dead good fun for anyone interested in cryptography puzzles themed around exciting storylines.
