About the game

Nina discovers the thirty-year-old chronicle of the Under the Crown Club. Someone is adding new messages between the old drawings. Keepsakes disappear in successive photographs of a shelf, and an old route crosses a park that has changed over time. Choose the order of three packs: People, Places and Keepsakes. Match memories to documents, compare maps from two periods and form shared conclusions. Revealed cards remain available, hints have no penalty, and an incorrect idea never locks the next part. The final chapter brings a meeting and an exhibition-label activity. A cooperative paper adventure for 2–4 players aged 8–12, without a required facilitator. Players can point, dictate or draw their answers. Cards work on full sheets, and the maps sit beside each other. All game materials are in Polish; this English text describes the product. One fixed mystery, with no timer or limited actions. The intended 60–85 minutes of play and around 15 minutes of preparation after reading, excluding printing, remain estimates. Review and sequence modelling have been completed. Playtests with children, a physical print check and independent preparation by a new person are pending.

What is included?

6 PDFs in each full colour and black-and-white edition. Rules, Nina’s entry, the initial shelf photograph, 12 document cards across three packs, two A4 maps, three photographs of changes, four chronicle extracts, five character cards, three conclusion bookmarks, three exhibition labels, six hints and a separate finale.
