The Bletchley Park 30 Day Challenge

Back in March 2020, just before the first Covid-19 Lockdown I was still working at Bletchley Park and with input from some of my colleagues in the Learning team devised 30 challenges which were tweeted 3 per week over the following 10 weeks. We bashed these out over the weekend, in our own time, before being furloughed but a whole load of love (and mild obsession) for all things Bletchley Park went into devising these in a short space of time.

Now we're in our third (ish) lockdown, for most of the people who worked on them their time at BP is but a distant memory, having been made redundant* some months ago. The challenges themselves have disappeared into the depths of BP's social media feeds... until now!

I've collected all 30 tweeted challenges and embedded them into one page so that you can work through them all at your leisure, or just pick and choose the ones you fancy!

Click the screenshot below to find them (but don't tell anyone! Mum's the word...**):

If you click on the timestamp at the bottom of each embedded tweet you will be taken to the original post on twitter, where you can see conversations resulting from each one, and maybe get one started again! Better still, why not respond to the original posts for the challenges you complete with a picture or other content showing off your work!

* Including me. Needless to say, neither this post nor the page to which it points are at all sanctioned or endorsed by the Bletchley Park Trust and if they'd compiled these challenges on their own website I would certainly have linked to that instead.

** No isn't. Please tell everyone! It's not secret any more...

The Alan Turing Cryptography Competition

Each year, starting towards the end of January, the maths department at the University of Manchester release their Alan Turing Cryptography Competition into the wild.

Much like the National Cipher Challenge it consists of multiple challenges of increasing difficulty that are released on a weekly basis, usually on Mondays.
