Name & Purpose Radar is a listening and awareness game. One player sits blindfolded in the centre of a circle, guarding a set of keys placed under their chair. Other players try to sneak in and steal the keys without being detected. The Sentinel uses their hearing to “point like radar” at the approaching player. Use it to build focused listening, patience, and body awareness. Works well as a calming mid-session activity.
a.k.a. Guardian of the Keys | Blind Sentinel
Age Band / Group Size / Time / Space Ages 8β16 | 10β30 players | 15β20 minutes | Medium room or sheltered outdoor space. The circle should be roughly 5β8 metres in diameter so the Retriever has space to move but not too much distance to cover silently.
Materials
- One sturdy chair
- One blindfold (a clean bandana or fabric strip)
- One set of keys or a small item that makes a faint sound when touched (metal key ring, small bell, a cup of dried beans)
- Optional: a soft mat under the chair so footsteps on hard floors are muffled
Quick-Run Card
- Players form a circle, seated or standing. One volunteer sits in the centre chair, blindfolded. Place the keys under the chair.
- Counsellor silently points to one Retriever in the circle.
- Retriever creeps toward the chair and tries to grab the keys.
- Sentinel listens and points toward any sound they detect. One point per round: if the Sentinel points directly at the Retriever, the Retriever returns to the circle and the round resets.
- If the Retriever grabs the keys without being pointed at, they become the new Sentinel.
- Counsellor picks a new Retriever. Repeat.
Setup & Boundaries Place the chair in the exact centre of the circle. All circle players must stay outside a marked boundary line (rope or cones) β they do not inch forward. Silence rule: everyone in the circle is silent during each attempt. Only one Retriever moves at a time. The Sentinel gets unlimited pointing β if they think they hear something, they point. Counsellor confirms whether the point is accurate (within arm’s reach of the Retriever’s current position).
How to Play The Sentinel sits in the chair, blindfold on, hands resting on their knees. The counsellor silently (using gesture only) selects a Retriever from the circle. The Retriever stands and begins to move as quietly as possible toward the chair. They must take the keys from under the chair β not kick them, not slide them β actually pick them up. The Sentinel listens for any footstep, breath, or rustle. When they hear something, they point toward it with one arm. The counsellor watches and decides: is the Sentinel’s point within one arm’s length of the Retriever? If yes β the attempt fails, the Retriever returns to the circle, and the counsellor selects a new Retriever (the Sentinel stays in). If the Retriever gets the keys and stands up with them, everyone cheers, the Retriever removes the blindfold and takes the chair, and the previous Sentinel returns to the circle. The counsellor chooses the next Retriever. Keep rounds short β swap the Sentinel regularly even if they are successfully stopping everyone.
I-OPt Roles Three simultaneous participation paths run during every round:
- Sentinel (active listener) β sits in the chair, uses hearing to detect movement. Suits players who like focused, individual challenge.
- Retriever (active mover) β creeps silently toward the chair. Suits players who like physical strategy and risk.
- Circle Analyst (observer) β all circle players track the Retriever’s path and make a silent prediction about whether the attempt will succeed. After each round, counsellor asks the group “How many thought the Retriever would make it?” β hands up. Keeps the whole circle engaged.
Inclusion Supports
- Players who are blind or have low vision can serve as Sentinel without the blindfold (they are already navigating by sound). This is a natural, non-stigmatising role for them.
- Players with hearing impairments can serve as Retriever β this role relies on movement skill, not hearing. They can also serve as Circle Analyst, watching and predicting.
- Players with mobility limitations can participate as Sentinel (seated role) every round if they prefer. Counsellor frames the Sentinel as the most powerful position in the game.
- Avoid forcing players into the blindfolded role β always ask for volunteers.
Stewardship Return the keys, blindfold, and chair to storage after play. 30-second reflection: stand still for a moment and notice three sounds in the room right now that you were not paying attention to before the game. No need to share β just notice.
Consent Pre-brief: “One player will be blindfolded for this game. Blindfolds are always voluntary. If you do not want to wear a blindfold, you can still play as Retriever or Circle Analyst. No one will be asked to wear the blindfold without choosing to.” Mid-game check-in: After three rounds, ask the current Sentinel if they are comfortable continuing. Give them an easy way to step down: “Want to stay in or swap out?” Opt-out/re-entry: Any player can step out of the circle to the sideline at any time. They re-enter by stepping back into the circle before the next round.
Risks & Mitigation
| Risk | Likelihood | Mitigation |
|---|---|---|
| Blindfolded player feels disoriented or anxious | LowβMedium | Use a light, breathable blindfold; allow player to remove it any time; keep the counsellor close. |
| Retriever moves too fast and trips or collides with chair | Low | Brief players: slow and deliberate movement only; no lunging or diving. |
| Circle players distract the Sentinel with deliberate sounds | Low | Pre-brief: making deliberate distracting sounds is not part of the game. Redirect immediately if it occurs. |
| Game becomes repetitive if the same Sentinel keeps succeeding | Low | Counsellor rotates the Sentinel role proactively β celebrate a successful run and swap them out with a “champion’s exit.” |
Warm-Up Suggestions
- Sound Map: Everyone stands still for 60 seconds and counts how many distinct sounds they can hear in the room. Sharpens listening before the game.
- Slow Stalk: Pairs. One player tries to walk silently from one wall to the other while their partner (back turned) tries to hear them. Switch. Just 2 minutes. Primes the movement and listening skills used in Radar.
Debrief What? Ask: “What helped you detect β or avoid detection? What made the most noise unexpectedly?” So what? Ask: “When do we need to tune in carefully to what is happening around us without being able to see everything? Think about teamwork, looking after a younger camper, or navigating a dark cabin.” Now what? Ask: “What is one situation coming up this week where slowing down and listening carefully might make a difference?”
Cleanup & Reset Return chair, blindfold, and keys to their storage location. No other setup required.
