Engage young minds with stamp collecting through fun quizzes
Stamp Detectives turns a real stamp into a three-clue mystery. Associations host a monthly quiz, local clubs climb the leaderboard, and club members can send a case straight to a grandchild's phone.

How it works
Three simple steps, whether you are a national association, a village club or a grandparent at the kitchen table.
1. Add a stamp
An Association assistant, a local club leader or club member uploads or photographs a stamp. Our photo identification system reads it and writes the questions and fun facts automatically.
2. Young detectives investigate
Children guess the theme, the country and the year — no account, no passwords, just three clear steps on any phone or tablet.
3. Scores come back to the club
Every completed quiz is logged against the local club, so association leaderboards update themselves.

Register your associationFrequently asked questions
- Do children need an account?
- No. A child receives the quiz through a local club member, usually a relation. We never store a child's name.
- What does it cost?
- Every Association receives 20 credits. Every club starts with 10 free stamp credits for their own local quizzes. Every club member get 5 free credits to use between Granddad and Grandchild. After that, small top-up packs cover the cost of the stamp identification — quizzes from your Association are always free to play.
- Does it work on phones?
- Yes. The whole site is designed mobile-first, so quizzes work on phones and tablets as well as laptops.
- How do we get our association on board?
- Fill in the Association Register form and we will set up your association, show you how to link your clubs and get your first monthly quiz ready.
