Sorry, certificates are generated after the end of each round. Should try to make that more explicit I guess!

Ah! That makes (some) sense! Is there any way to hide/remove the ‘get your certificate’ button until each round is over?11th October 2019 at 2:31 pm #43209
Probably, but instead we are making the certificates available early for now. Could you check again to see if you have still not got yours?

Looking at the leaderboard, the function to filter by school looks very useful (especially for teachers!) – why do all the school names have an ‘A’ appended to the end?17th October 2019 at 1:15 pm #43589
A bug, not a feature! Thanks for pointing it out.

In the part A, in the decrypting bar A, as the numbers are all the odd numbers, shouldn’t there be a 13 between 11 and 15?17th October 2019 at 6:13 pm #43646
Excellent question, to which the answer is, surprisingly, No!
What is it that the even numbers 2-24 have in common with 13?
All the best,

The link to: Programming for Cryptologists 101 pdf, by Julian Bhardwaj from
Returns the cryptic message “404 Not Found”….21st October 2019 at 1:42 pm #43739
Thanks for pointing that out. Fixed now. Let us know if we missed anything else.

Thanks for fixing that link. There’s a similar issue on…
The link for “PROGRAMMING FOR CRYPTOLOGISTS 101”, “Download programming guide” also returns 404 Not Found.

Another excellent catch. Hope it works now.

Here, “0” denotes an unknown value, 11 = jack, 12 = queen, 13 = king, A = joker A, B = joker B, C = clubs, D = diamonds, H = hearts, S = spades.
I have a image of the above cards showing the following
Were all X are card backs.
Hope this helps.24th October 2019 at 8:45 am #43797MadnessMember
That sounds like it was the second hint. I don’t have that image, so would you please go to
and upload the image? Then I will add it to the archive. Thanks a lot!24th October 2019 at 8:45 am #43798MadnessMember
@The-letter-wriggler, any chance you or someone at your school/club/wherever still has a copy of the cards from 2010?24th October 2019 at 8:50 am #43802
Madness, thanks to my colleague Jim Renshaw we have been able to reproduce the crib images for 2010 as requested. You can download them as a zip file here:
Let me know if that is what you needed.
