Challenge 10A

[Harry]

This is the place to post hints, tips, cries of frustration and desperation etc! We will moderate them to make sure that we don’t give away too much, and you will maximise your chance of getting published if you make it suitably witty, wise, insightful etc. But do be kind. We will not publish “Ha ha we dun it, aren’t we clever” posts even if the people posting them are indeed very clever!!

Could it potentially be anything we have done before (i.e. last year was a Polybius cipher)

It could always potentially be something you have done before. It is rarely something you have done before! Harry

@Harry wdym?

I mean that nothing is off the table when I design Challenge 10B except I don’t like to copy something I have done before. That is all. Harry

The challenge says there should be a case file at 7am on Saturday 20th for challenge 10A, however I can find nothing in the case files?

Apologies, we had the date in the wrong format! It should show now. Really sorry to everyone who has been waiting all day for the hint. Harry

Has the release of Case File 10.1 been delayed? The latest News post says it should’ve been out by 7am today but I can’t see any updates under the case files section

Yes, mea culpa! Had the time in the wrong format. Fixed now. Harry

[ByteInBits]

should the following have been posted ?
Case File 10.1 (Challenge 10A only) 7am, 20th December

See apologies passim! Had the date/timecode wrong. Harry

[BuzzBoy]

Ayo @harry, where is case file 10.1?

It was published at 7.30am on 20th December 2026, sorry. (See “Who is Harry?” on the FAQs for more details. Harry

Hi Harry,

I just wanted to say that Case File 10.1 was due for release this morning at 7am but has not been released yet. I don’t know if this is deliberate or not, but it could cause some annoyance if not.

PS: My team have already solved 10A so this doesn’t really impact us.

Thanks to everyone who pointed this out, we are really sorry for the delay. Explanation elsewhere in the thread, so I won’t repeat it here, but I will repeat the apology! Sorry, Harry

[PlaintextPersuers]

We’ve managed to crack 10A but just noting that we’re not seeing the case file that was due to be released at 7AM this morning. We were curious as to what it was going to be, but others may be waiting eagerly for the hint so we thought we’d let you know Harry…

Thank you, we are really grateful to everyone who pointed this out and extremely sorry to disappoint everyone who was waiting for the hint. We have a nasty feeling you will be even more disappointed when you see it! Harry

[Foxboy]

Hi, I can’t see the casefile 10.1 which was supposed to be published at 7am today? How do I find it? This is a tricky one!

Without a Time Machine it was impossible! See explanation above in this thread. Apologies to all the non-time travellers here, we will take account of the availability and use of time machines in the leaderboard we promise. Harry

[philipph317]

Well, it is indeed related to something that you’ve solved before, and it is not as complicated as you might have thought!

Or indeed, as complicated as Casefile 10.1 (which has finally appeared) would make it seem. We will be intrigued to see your interpretations of the information in it! Harry

i finished 10a on thursday, but i wanted to see the case file out of curiosity. is it up yet? a few things have said so but i can’t find it anywhere

More a matter of anywhen. See apologies and explanations above! Harry

[Gen_ruikt]

Just wondering was casefile 10.1 meant to come up today for 10a and will 10.2 be out tmmrw

Really sorry about the delay. It was/wil have been meant to come up today, but was accidentally scheduled for a date in the future. The Casefile has been retrieved from then and should now be available. Harry

[F6EXB_the_frenchy]

The histogram is the alpha and omega of decryption.

[Rhadamanthus]

I have seen the case file now, thank you Harry, although my team has now solved 10A.
