Hope you all had a fantastic break and are rested, refreshed and ready to go for the first competition round in this year’s National Cipher Challenge.
If you have just joined us, welcome (instead of welcome back), we are delighted to meet you and hope you have fun. If you want a warm up before the contest starts, you still have until 11pm on Wednesday to try Practice Challenge 3, and even if you feel confident, you might still want to take a look at it (and the first two practice challenges) to catch up either the story so far.
Challenge 4 will launch at 3pm on Thursday 5th November. We can;t promise fireworks, but we do promise excitement. Hope to see you there.
