Ssh don't tell*, but cipherchallenge.org has soft-launched for a week of bug hunting before we go live with the 25th National Cipher Challenge! Registration opens 24/09, competition starts 08/10, but if you want a sneak peak ... *Actually, please tell everyone!

ALT Poster for the 25th National Cipher Challenge, The Mystery of the Missing Silver at cipherchallenge.org.uk. £6K in prizes; registration opens 24th Sept; competition starts 8th Oct. Run by the School of Mathematical Sciences at the University of Southampton and Trinity College, Cambridge. Sponsored by GCHQ, Northrop Grumman, EPSRC, the Bluespark Foundation and 10Degrees.

Perfect preparation for the @MathsSoton National Cipher Challenge, starting in September. Produced in partnership with @GCHQ. Bookmark cipherchallenge.org so you don't miss it.
Maybe I should be more direct! Last year over 800 schools took part in a maths competition that cost nothing (and didn't have to cost teachers
any time either)! Why let them keep all the good stuff to themselves? Head to cipherchallenge.org for more info

Would this be a good time to point out that @MathsSoton offers a self-contained free STEM enrichment activity throughout the Autumn term that needs no work from busy teachers? Ideal for an after-school club or just advertise it. Head to cipherchallenge.org for more info.

(Sorry to barge in, but this looks like a crowd who might appreciate it) If you want inspiration for a maths or computing club, the 25th National Cipher Challenge posters will arrive in schools around 7th Sept. Would love to beat 10,000 registrations this year.
Hmmm, found this walk on the OS app. Puzzled, since it is a circular stroll. Best guesses so far: 1) it's a relativistic effect and the walker ran at approx 40% of the speed of light on the climbing segments; or 2) the OS commissioned Escher to design the walk. Any other ideas?
Just like last year we broke the records for Challenge 2 entries with nearly 8100 of you signed up to take part. Practice Challenge 3 starts at 3pm today, so if you haven't signed up yet head over to cipherchallenge.org to get involved
The clock is ticking down to the 3pm start of Practice Challenge 2 at cipherchallenge.org! We had over 7000 registered for the first round and there is still time to register for the competition. Hope to see you there!
