MAKE ROOM FOR A LITTLE MYSTERY

The moment they say,
“Wait. I’ve got it!”

A clue passed across the table. A lively debate over a suspect. That grin when the pieces finally click. This is their story to solve together.

INSIDE THE HOST’S OWN PLAYBOOK
The current Host Guide: scripts, hints, answers and revealsA REAL ROLE IN THE GAME
DETECTIVES INVESTIGATE. THE HOST IS MISSION CONTROL.

The host brings
the adventure to life.

The host has a part to play from the opening dispatch to the final reveal. With their own script in hand, they tell the story, respond to the team’s discoveries and unlock the next stage of the investigation.

  1. Speak as Mission Control. Read the opening briefing and deliver the story’s next message.
  2. Unlock the next evidence file. Check the team’s submission, then hand over the next packet when their Gate is accepted.
  3. Follow the investigation. Verify suspect-board moves and give the matching story response.
  4. Keep the adventure moving. Offer hints when requested and deliver the final reveal.
FROM THE INCLUDED SCRIPT
“Gate accepted.”

Then do this: Hand over the next packet. Players dock the Evidence card they earned.

The host sees the answers and plays a different role from the detectives solving the case. The guide provides the words, checks and hints to run it.
