🕵️ The Secret Detective File: facilitator kit
Teens and adults · 15–25 minutes · Level: Easy · 6 stages
Opening story: An anonymous detective left a secret file. Inside are three clues, and every answer brings you closer to opening the safe.
Setup
- A brown “TOP SECRET” folder or envelope
- 3 suspect cards
- Printed clue notes
- A small safe or a box with a number lock
- Print the 6 stage cards and put them in order, or hide each card around the room so every answer leads to the next one.
- Read the opening story to the group and start a timer.
- When the group gets stuck, give one hint from the table, one at a time.
- Print the suspect cards and write on each one only the sentence that suspect said.
- Give players scrap paper for the logic stage; it helps to test each possibility separately.
- Set the safe’s lock to 15 in advance.
