The case
At 20:17, during the opening of a special exhibition at an art museum in Aarhus, the curators discover that a rare glass sculpture in display case M4 is a copy.
The alarm never went off, and the case was never opened during the reception. Somewhere between a safety check in the afternoon and the party in the evening, the original vanished.
Your mission
- Find out who removed the original sculpture.
- Explain how the swap was hidden – and when it really happened.
- Find out where the original was taken.
- Back up your accusation with at least four document numbers.

How Game Night works
- Print the case file (18 documents) and sort it into the START folder and 2 sealed envelopes. The first page tells you how.
- Investigate at the table. Share out the documents, compare times and statements, and argue it out. Your phone just stays on the table.
- Open the envelopes when you've cracked each checkpoint. The site checks your answer and gives hints if you get stuck (each costs a point).
- Make your accusation together: the culprit, three key questions and at least four pieces of evidence. You score up to 20 points – then reveal the full solution.
