A hands-on detective game by post. Solve puzzles, uncover Greek myths, and track down the Lost City of Atlantis.
It begins with a mysterious letter requesting assistance in locating the Lost Island of Atlantis.
The Atlantis Case File
In 1930, a marine archaeologist recovered strange artefacts from the wreckage of an ancient vessel. The objects were catalogued, boxed up… and then quietly forgotten.
Now the case has been reopened. Those artefacts, and the secrets they carry, are being sent to your investigator. Each clue nudges them closer to the truth – if they can crack the codes.
What arrives in the post
Across three mailings (or one all-in-one pack), your investigator will receive:
- Photographs and postcards from the expedition.
- Letters, scribbled notes and maps from the archaeologist’s desk.
- An “ancient” coin and other tactile artefacts to examine.
- Newspaper and magazine clippings hide subtle clues.
- Codes, cyphers and puzzles that, when solved, reveal the location of Atlantis.
Everything feels like it came from a real case file – right down to the paper, stamps and markings.
Who will love this?
- Best for ages 10+ – younger children can absolutely join in with a grown-up’s help.
- Perfect for siblings and families who want a shared, screen-free adventure.
- Ideal for birthdays, school holidays, and rainy-day investigations.
- Great gift from parents, grandparents, aunts, uncles or family friends.
How it works
- Choose your format – three separate mailings or an all-in-one delivery.
- Add your investigator’s name and decide whether to reveal yourself as the sender at the start or let them discover you at the end.
- We post from the UK – the case file arrives through the letterbox, and the investigation begins.
No app or screen is needed – everything happens with the letters and artefacts spread out on the table.
