Quick-Run Card
- Facilitator reads the clue: “I want to go home, but the person in the mask won’t let me. Who is the person in the mask?”
- Players ask yes-or-no questions to figure out who the masked person is.
- Facilitator answers only yes, no, or “doesn’t matter.”
- Players may confer quietly before asking.
- Round ends when the group solves it or time is called.
Setup and Boundaries
- Seat players in a circle or semicircle so everyone can hear
- Signal: one raised hand = pause; two claps = time called
- No physical setup required
How to Play
- The facilitator reads the clue: “I want to go home, but the person in the mask won’t let me. Who is the person in the mask?”
- Players take turns asking yes-or-no questions. The facilitator may answer: yes, no, or “that doesn’t matter.”
- Players confer quietly between questions , team thinking is welcome.
- Nudge players to think about: Where is this happening? Is the mask a costume or protective gear? What sport uses home base?
- If the group is stuck, offer one gentle nudge per minute.
- When someone names the answer, the facilitator confirms. Celebrate together.
Answer (for facilitator only)
- The narrator is a baseball player trying to run home (home plate). The person in the mask is the catcher, blocking home plate.

Inclusion Adaptations
- Players who prefer not to speak aloud can pass written questions to a partner
- Small groups of 2-3 may confer and ask as a team
Stewardship Moment
- No materials, no footprint
- Optional connection: “Baseball stadiums are maintained by a lot of people working together. Who at camp keeps our space working well for everyone?”
Consent
- Pre-brief: “There’s a surprising answer here , and all questions are good questions. Jump in whenever you have one.”
- Mid-game check: After 5 minutes, pause. “Still enjoying this? Thumbs up, sideways, or down.”
- Opt-out/re-entry: Listen quietly at any time and join in whenever you’re ready.
Risks and Mitigation
- Players unfamiliar with baseball may need a nudge: facilitator can hint “think about a sport played on a diamond-shaped field”
- One player knows baseball well and guesses immediately: ask them to hold their answer and coach others with yes-or-no questions instead
- Puzzle too easy for older groups: challenge them to solve it in three questions
Warm-Up Suggestions
- “20 Questions”: think of a person, place, or thing; group asks yes-or-no questions
- “What Sport Am I?”: describe equipment used in a sport without naming it; group guesses
Debrief Questions
- What? “What question cracked the puzzle? What made it the right question?”
- So What? “How did the language of the clue mislead you? What assumptions did you make?”
- Now What? “When is it useful to ask ‘what context am I missing?’ before reacting to something?”
Cleanup and Reset
- No materials to reset
- Move to the next mystery or activity
