Quick-Run Card

1. Seat the group in a circle.
2. Describe the scene: “A person named Joe is found alone in a room. There are three sets of tracks leading in and two sets leading out. There is a wet patch on the floor beneath him. What happened?”
3. Group asks yes or no questions.
4. Staff answers yes, no, or “not relevant.”
5. Reveal and debrief.

Setup and Boundaries

• Seat the group comfortably
• Signal: raised hand = pause and listen
• No physical setup needed

How to Play

1. Facilitator describes the scene clearly and slowly.
2. Players ask yes or no questions in turn.
3. Facilitator answers: yes, no, or “not relevant.”
4. If the group is stuck, offer a hint: “Think about what could leave a wet patch and also explain the extra set of tracks.”
5. Full answer for the facilitator: Joe chose to end his life. He had a large block of ice delivered, stood on it, and let it melt. The three sets of tracks were Joe, the delivery person, and a hand-cart; the delivery person left with their cart, leaving two sets of tracks out.
6. Confirm the answer and move to the debrief.

I-OPt Options

• A (Active): Ask questions and propose explanations aloud
• S (Support): Help the group track what has been confirmed or eliminated
• Q (Quiet): Follow along and signal agreement quietly
• O (Observer): Watch the reasoning process; join when ready

Inclusion Adaptations

• Players may write questions and pass them to the facilitator
• Smaller side discussions welcome before sharing with the full group

Stewardship Moment

• No cleanup needed
• Reflection: “What does it mean to piece together a picture from partial information?”

Consent

• Pre-brief: “This puzzle involves a serious and heavy scene. If this feels like too much today, you are absolutely welcome to sit this one out or take a quiet observer role. We will move on warmly either way.”
• For those not comfortable with any part of this activity, sitting out or joining as an observer is another option.
• Mid-game check: Check in with the group after a few minutes. Anyone looking withdrawn should be gently offered a break.
• Opt-out/re-entry: Step back at any time.

Risks and Mitigation

• Content involves suicide: facilitator must be confident this is appropriate for the specific group before using this puzzle. When in doubt, choose a different puzzle from this series.
• A camper has personal experience with this topic: if a camper becomes distressed, pause the activity immediately, step in warmly, and follow your camp’s wellbeing protocol.
• Puzzle solved quickly: move straight to the debrief and lean into the reflection questions

Warm-Up Suggestions

• “Scene Detective”: describe a simple scene (e.g., “There is a wet umbrella by the door and muddy boots”) and ask players to infer what happened
• “Two Truths and a Lie” to warm up reasoning

Debrief Questions

• What? “What piece of the puzzle was hardest to figure out?”
• So What? “How did the group’s thinking change as you gathered more clues?”
• Now What? “Where in your life do you have to make decisions based on incomplete information?”

Cleanup and Reset

• No cleanup required
• Store printed clue cards for reuse
