Welcome to 18 Clues! As you haven't bought from us before, please select the POSTAL delivery format option at checkout for your first order. We will then send a Welcome Card with tips, offers and other information with your first Challenge(s). For subsequent orders, you will be able to choose between POSTAL or PDF Download.

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, or a Virtual Challenge, which you can complete online, anywhere you choose, using tools such as what3words, Google Maps and your preferred search engine. Assuming you solve all 18 clues correctly, 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.
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 Card you buy will be donated to an animal welfare and/or environmental charity.

The Perfect Gift Anytime
Give the gift of adventure with an 18 Clues Gift Voucher.
You can choose to have the gift voucher emailed to yourself to print out and present in person, or you can choose to have the voucher emailed directly to the recipient on a date that you pre-schedule.
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. You then simply insert the voucher you have purchased and present to your friend or loved one. Twenty percent of revenue from all gift vouchers purchased will be shared amongst the participating animal and/or environmental charities.
IMPORTANT: If you are buying a gift for others, always buy a gift voucher. Why? Whenever you purchase a Challenge through the Challenge Shop, a 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.

Featured Challenge and Charity
Welcome to our first 18 Clues Challenge location... London: West End, Royal Parks and Mayfair. With dazzling theatres, galleries, hotels, shops, residences, historical royal parks, and restaurants, this is one of the most vibrant and exciting places on the planet, and a great place to explore on foot and/or virtually.
Backstory: An evil villain - known as The Disruptor - intends immobilising the West End by releasing a gas bomb that will temporarily freeze every living creature in their tracks! Can you locate the device before chaos ensues?
We are pleased to announce that £2 from every copy of London: West End, Royal Parks, Mayfair sold will be donated to the wondrful Battersea Dogs and Cats Home.
Established in 1860 by Mary Tealby, Battersea is one of the UK’s oldest and best known animal rescue centres. Offering love and expert care to dogs and cats in need by rescuing, rehabilitating and rehoming animals, Battersea also shares their knowledge and resources with rescue organisations around the world.
After purchasing your first 18 Clues Challenge, we urge you to click on the 'Challenge Charity' box below to learn all about Battersea, and the incredible work it does helping ‘every cat and dog in need – whether its newly born or getting on, cute or cute in its own way’. We are sure, like us, you will become completely engrossed.
We will publish a Walking and Virtual Challenge for a new location each month. A specific charity will be linked to each duo of Challenges, but as all Challenges will remain available for purchase in our ever-increasing catalogue, all participating charities will benefit on an ongoing basis. Our prize packages will change quarterly, with each prize draw closing at midnight on the final day of the quarter. All correct answers submitted will be entered into the prize draw active at the time of submission.
We now invite you to click through to our Challenge Shop and start exploring...
