Materials

Quick-Run Card

One player (the Detective) leaves the room or steps out of earshot.
The group quietly agrees on a secret rule (for example: answer truthfully when legs are uncrossed, lie when legs are crossed).
The Detective returns and asks questions to any player in the circle.
Players answer according to the rule.
The Detective has 3 guesses to name the rule. Then a new Detective is chosen.

Setup and Boundaries

Players sit in a circle with clear sight lines to each other.
The Detective waits outside the door or far enough away that they cannot hear the group.
Signal: a knock or staff call of “Ready!” brings the Detective back in.

How to Play

Players sit in a circle.
One volunteer becomes the first Detective and steps outside the room or out of earshot.
The group quietly agrees on a secret rule. Examples: answer all questions in exactly five words; start every answer with a vowel; tell the truth when arms are crossed, a small fib when arms are at your side.
Staff calls the Detective back in.
The Detective asks questions to any player in the circle. Players answer strictly according to the rule.
The Detective has 3 guesses to identify the rule. After 3 guesses (or a correct guess), the round ends.
A new Detective volunteers or is chosen by the group. Set a new rule. Repeat.

I-OPt Options

A (Active): Volunteer as Detective and ask creative questions to narrow down the rule quickly.
S (Support): When setting the rule, suggest ideas and help the group agree quickly and quietly.
Q (Quiet): Answer questions in the circle according to the rule, no extra contribution required.
O (Observer): Watch from the circle without answering. Try to figure out the rule from the sideline.

Inclusion Adaptations

Players who are not comfortable leaving the room can stay just outside the circle with their back turned instead.
Rules can be adapted to be entirely verbal (no physical cues like leg crossing) for players with limited mobility or who prefer not to draw attention to body position.

Stewardship Moment

No materials needed and no waste. A purely human-powered game.
Optional reflection: “We just ran 20 minutes of entertainment using nothing but our brains and each other.”

Consent

Pre-brief: “In this game the Detective asks questions and tries to figure out a secret rule. For those who prefer not to be the Detective, there is no pressure. Being in the circle and answering questions is a full and important role.”
Mid-game check: After two rounds, check if anyone wants a turn as Detective who has not had one yet.
Opt-out/re-entry: Players can pass on answering a question by saying “Pass” with a wave. They can re-engage on the next question.

Risks and Mitigation

Detective feeling publicly stumped or embarrassed: frame 3 missed guesses as a win for the group, not a loss for the Detective.
Group not keeping the rule secret or giggling too early: remind players the fun lasts longer when the rule holds.
Rule too easy or too hard: staff keeps a short list of starter rules at different difficulty levels to suggest if the group gets stuck.

Warm-Up Suggestions

“Two Truths, One Lie” mini-round: each player says two true things and one false thing about themselves. Group guesses which is the lie.
Quick pattern round: staff demonstrates by calling out three things that follow a rule (for example: cat, door, pool) and asks what they have in common (double letters).

Debrief Questions

What? “What question gave you the most useful information?”
So What? “How did it feel to hold the secret while the Detective was asking questions?”
Now What? “Where in everyday life do you look for patterns before jumping to a conclusion?”
