The maths department at Manchester University recently launched a new competition tied in with the release of *The Imitation Game*, the film about Alan Turing that you have no doubt heard of.

The competition involves decrypting three codes. I thought it was quite fun, if not particularly difficult. Here’s the link.

A new trailer for the film came out a couple of weeks ago. I’m quite looking forward to this. Hope it doesn’t disappoint.

Solving the clues is quite fun.

I am currently stuck at the second one. You seem to have solved this. Can you give me a hint please.

Hi Elaine.

There are (I think) 30 different symbols in the ciphertext, which is more than the number of letters in the alphabet. What do you suppose this could this indicate?

can i have a hint for clue 2?

I’ve already left a hint for Elaine. Here’s one more, and that’s your lot :-P

Ab. Pna ibh tvir zr gur jbeq v fubhyp ybbx sbe?

I have been trying for hours. I dont understand the clues/not helpful enough for my thick brain. Any help please??

I have no clue how to solve 2. I need a clue or I am giving up. I have tried every word from the map and am not sure what to do from here.

Phil, have you managed to solve it?

Yes :-) But I think I’ve given away enough clues. I’ll post a solution here after the competition closes.

Nooo!! thats in ages! we need another clue! Do I have to solve 3 first? what word should i look for? Is it on the map? Do I need to use a computer to solve it? do I need to wait till dawn and then hold it up to the light?

Please could you give a bit more of a clue regarding the relevance of there being 30 symbols?

could you at least tell us what type of cipher/code it is? please :>

It’s one of these. That’s all I’m saying.

well that’s too hard could you tell us the first word, pretty please with a cherry on top and little chocolate chips :)

All right then. It’s one of these. Now please try to figure this thing out for yourself :-P
