One mystery. A whole room of teams.
A printable game can work for a classroom or workplace when each team has its own space, materials and opportunity to contribute.

Build small teams
Plan for two to six players per team. Give each team a printed player booklet, pens, and a place to record answers. An event license covers up to 30 players; a large event license covers up to 120. Each covers one gathering.
Brief everyone together
Read the story once to the room. Explain where hints come from, how to check answers, and whether teams are playing against a countdown or at their own pace. Keep the host guide away from player tables.
Keep progress fair
Use the same hint policy for everyone. If a group asks for help, offer a small nudge before revealing a complete step. Encourage discussion within teams rather than calling answers across the room.
Debrief the experience
Ask which clue changed someone’s mind, what made the team communicate well, and how they handled a wrong turn. In a classroom, connect the discussion to careful reading, sequencing and explaining reasoning.
