How 18 Clues Works
You go to our Challenge Shop and purchase one or more of our 18 Clues Challenges. You can choose a Walking Challenge, which requires you to visit the location and find the clues in person, and/or a Virtual ('Armchair') Challenge, which you can complete online, anywhere you choose, using tools such as what3words, Google Maps and your preferred search engine. Solve all 18 clues correctly and you will be left with the correct solution to the Challenge, which you can then submit online to be entered into an amazing prize draw.
A new pair of Challenges featuring a new location will be released each month. All clues, facts and solutions in the Walking and Virtual Challenge versions are different, so if you are able to visit the Challenge location you can complete both Challenge versions to double your chances of winning the prize. As you explore the location, be it physically or virtually, you will learn loads of interesting facts... but best of all, a healthy percentage of the price of each Challenge or Gift Voucher you buy will be donated to an animal welfare and/or environmental charity!

A £10 gift Voucher will buy the lucky recipient one Walking Challenge activity to enjoy with friends or a Virtual Challenge to play at home, plus a 25% discount on a second Challenge.
If you choose to have the gift voucher emailed to yourself, you can buy Stylish Presentation Sleeves from our Challenge Shop for just £2, including postal charges.

A GIFT FOR YOU... Buy a minimum of £30 worth of Gift Vouchers in one order and within 24 hours you'll receive a code enabling you to order a complimentary Challenge of your choice.
IMPORTANT: If you are buying a Challenge for others, always buy a gift voucher. Why? Whenever you purchase a Challenge through the Challenge Shop, a Unique Reference Number (URN) is generated that is specifically linked to you and your contact details, so only you will be able to request answers to clues or submit the final answer. If, however, you buy someone a gift voucher, they can choose whichever Challenge(s) they wish, and when they redeem their voucher they will be registered as a member in their own right.

Latest Challenge Release
The Location... The intellectual beating heart of London, Bloomsbury and Holborn blend academia, culture, history, eclecticism, and allure. Bloomsbury is synonymous with bookish charm, leafy garden squares, and the ghosts of literary giants lingering in the air. Holborn, on the other hand, buzzes with legal institutions, ancient pubs, and hidden cultural gems. Both boast world-famous universities, museums, and libraries, and just about every street corner hides a fascinating story.
The Challenge... It has come to light that Charles Dickens, one of the world’s most celebrated authors and a former Bloomsbury resident, embedded an illuminating cryptic message in one of his many works. Your task is to discover which novel Dickens’ revelation is hidden in by finding and solving 18 clues.
About this Challenge... For more information specific to this particular Challenge location, please see ABOUT THIS CHALLENGE at the base of the specific Product Page in the Challenges Shop. Choose the Walking Challenge, the Virtual Challenge, or if you live near the Challenge location or plan to visit London, buy both to double your experience, double your knowledge and double your chances of winning the prize package!
The Charity... £1 from each London - Bloomsbury and Holborn Challenge sold will be donated to Urban Squirrels via Work for Good (see Challenge Charity box above right) , a London-based charity dedicated to providing vital care and advocacy for these super-intelligent and resourceful animals, highlighting their importance in urban ecosystems, and promoting coexistence. The organisation also challenges legislation that currently prohibits the release of rescued grey squirrels back into the wild. We urge you to spread the word to lend further support to this small charity.
