The website is stocked with information about the competition, including this FAQ, the About the Challenge page, the Rules and Regulations, and in the BOSS Trainers’ Manual. You can also follow Harry on Twitter for the very latest news and clues.
There is more infomation on our Resources page including notes on codebreaking, some class materials and a guide to programming for codebreakers.
It is also worth taking part in the forums, which we will monitor and where we will publish occasional updates and answers to common questions. Be kind to the Elves who staff the Forum. They work very hard to support you and can’t always answer queries immediately (it is, in Elf terms, getting close to Christmas and the sleigh needs packing).
