9th April 2020 at 9:32 am #4730010degrees-adminKeymaster8 mins, I found ms paint is very useful as the quickest tool to hand but not the easiest to write neatly with.
9th April 2020 at 9:45 am #4730110degrees-adminKeymaster15 minutes, using logic not brute force

10th April 2020 at 11:51 am #47387Inactive11 minutes, 20 seconds
10th April 2020 at 2:00 pm #47390Inactivea chill 20 minutes, maybe less, a lil guesswork in excel with music in the bg for the fun of it (didn’t read over the time thing) (spent maybe 10 minutes checking haha)
11th April 2020 at 8:29 pm #4741810degrees-adminKeymasterFound it and started work on it around 11:30. Solved in about an hour and a half.
12th April 2020 at 10:09 am #4742610degrees-adminKeymasterDoes it need to be 13 mines? I can find a solution with 14 mines, but haven’t found one with 13….
12th April 2020 at 10:10 am #47428HarryKeymasterInteresting! We published the 13 mine solution this morning. If you want to publish yours we will be happy to check it!
12th April 2020 at 10:26 am #47431HarryKeymasterGCHQ Puzzle Challenge 2 is now up. Once you have solved any, post here saying which one and giving your answer. If it is right we will remove the answer and put up your post for the world to see. (It is the holiday, so you might have to be patient!)
12th April 2020 at 7:08 pm #47439HarryKeymasterSeveral guesses so far for books on GCHQ Puzzle Challenge 2. One or two have the right book in their answer, but none have the right twist! (Which, now I come to think of it, sounds a bit like I have added a version of the logic puzzle Mastermind to the mix!).
13th April 2020 at 9:58 am #4745210degrees-adminKeymasterNot sure I have fully understood what to do, but here’s my first couple of attempts: a, c
[Well done on the first two correct submissions to GCHQ Puzzle Challenge 2, Harry]
13th April 2020 at 11:36 am #47455InactiveI am also not quite sure which you want but my attempts are a) [Not quite, Harry!] and c) [Got it!, well done. Also Harry]
13th April 2020 at 11:38 am #47454InactiveNot sure what the ‘twist’ refers to
[That is the evil genius of this particular challenge. Once you have a couple the twist will be apparent. Good luck, Harry]
Of course I could just put twist on the end of title and it would surly have a twist ending! Ha ha.
13th April 2020 at 3:42 pm #47463InactiveNow I know what I’m doing:
a)
