Diver searching for Atlantis

The investigation begins…

In 1930 a Marine Archaeologist recovered underwater artefacts from the wreckage of an Ancient Vessel.

These remnants will lead your investigator through the legends of Ancient Greece, uncovering relics, codes and clues in search of the Lost City of Atlantis.

Three mailings containing:

Photographs, postcards, letters, artefacts including an ancient coin, newspaper and magazine clippings, all interweaved with codes, cyphers and puzzles that, when solved, will reveal the location of the Lost City of Atlantis.

Who can play this detective game?

The codes and cyphers are designed for 10 years and above; children under 10 years old can play but may require supervision with some of the more intricate puzzles.

Also suitable for siblings or families with younger children who want to explore the adventure together.
