Before you settle in

A few details. Then, on with the case.

What do you need to play?

The case printed on A4 paper, a pencil and a table. The game is designed for black-and-white printing. No cutting, homemade props, app or outside knowledge is required.

Can you play solo?

Yes. The game is designed for two adults sharing and challenging their ideas, but one person can also study all the documents.

How long does a game take?

The editorial target is 30 to 40 minutes for the full case and 5 to 10 minutes for the demo. These times have not yet been validated through human playtests and will depend on your pace.

What is included in the full case?

Eight game pages and a separate three-page file containing progressive hints, the solution and the ending. Keep the solutions closed until you need them.

Does the demo reveal the full case's solution?

No. The demo tells an independent story. It introduces cross-checking evidence without revealing the location or person in the full case.

Can you replay the same case?

Once you know the solution, the pleasure of discovery is gone. The case is therefore not designed to be replayed by the same people.

Is the game frightening?

There is no murder or threat. It is a deduction investigation into a disappearance at a museum, with documents to cross-check and a line of reasoning to build.

Can you already buy the case?

Sales have not opened yet. The free demo is available now. The price survey is neither an order nor a commitment to buy.
