Inside the experience.
Twelve objects are about to be sold. The curator is missing. Her last instruction asks you to find what the catalogue left out.
The Thirteenth Lot is a cooperative museum mystery for 2–4 adults. Your table becomes the investigation: printed catalogues, permits and conservation records combine with a paper city chart and an offline digital casefile.
What you actually do
- Compare evidence across catalogues, permits, photographs and conservation records.
- Build the chart from four printed pieces using borders and contact rings.
- Turn three selectors on that same chart as the case changes what you need to read from it.
- Reach a shared conclusion and deliberately confirm your final action.
The investigation runs through seven connected stages. Some are quick evidence decisions; the deeper work is in combining records and physically reusing the chart.
What is included
Complete English case, version 1.0.1: an 11-page A4 player PDF and equivalent 11-page US Letter PDF, the complete offline investigation, quick-start instructions, three levels of hints, full answers, and save export/restore.
Digital download only. No physical objects are shipped.
Set the table
For 2–4 adults at one table. Bring one desktop or laptop with Chrome, a printer, 11 sheets in one paper size, scissors and a pencil; tape is optional. Print single-sided at 100% / Actual Size. Cut four large squares and three small squares when instructed.
Start, save and replay
Extract the complete ZIP, read QUICK-START.txt, then open START-HERE.html. No host needs to know the answers in advance and there are no secret roles. Export a save before closing if local storage is uncertain.
The case and solution are fixed. Replay is about revisiting the same investigation, not receiving a new case.
Good to know
Private home play, personal backups and reprints for one table are included. Redistribution and commercial group use are not.
