The Glass Furnace

What’s inside

• The Case File with the documents marked D, the persons of interest and the three case questions
• Envelope A and Envelope B, each confirming one answer and adding new documents
• Envelope C: the full solution, as a separate file so nobody spoils it by accident
• Every file in a Colour Edition and a Printer-Friendly Edition (light backgrounds that save ink)

How to play

1. Print single-sided, or open the files on a tablet or laptop.
2. Print Envelopes A, B and C without reading them and seal each one in its own envelope.
3. Start with the documents marked D and read them as a team.
4. When you agree on the answer to question A, open Envelope A and check it. Then do the same for B and C.
5. Envelope C holds the full solution: who did it, why, and the evidence that proves it.

Who it’s for

Made for game night with friends, couples who like a challenge, families with older teens, book clubs and office groups. It also works solo. Spread the pages across a table, split the documents between players and argue it out. Plan for two to three hours. There are no hints and no detective notes: every answer can be proved from at least two documents.

Printing tips

Print single-sided on plain paper. The Printer-Friendly Edition uses light backgrounds and saves ink; the Colour Edition looks best on screen or on a colour printer. You can also mix: read on tablets and print only the pages you want to hold.
