Blind Polygon
The whole group stands blindfolded around a long rope tied into a loop. Their task is to form a perfect square with the rope held taut off the ground, without anyone looking. The group has to agree on how to communicate, who leads and how to check progress. When they think they are done, they look, and then talk about how they got there.
When to use Blind Polygon
Use when a team needs to look at how it organises itself, who takes the lead and who goes quiet, in a short shared challenge before a planning session.
What it solves
In real projects, the same people always lead and nobody notices that others have stopped contributing.
How to run Blind Polygon, step by step
- Tie the rope ends into a loop and lay it at people's feet (prep).
- Everyone puts on a blindfold or closes their eyes; explain the task and rules (3 min).
- The group forms a square with the rope taut and off the ground (15-25 min).
- When the group declares it finished, everyone looks at the result (1 min).
- Debrief: how did you decide, who spoke, what would you do differently next time? (10-15 min)
Materials needed
- A long rope (about 1 metre per person) tied in a loop
- Blindfolds or eyes-closed option
Facilitator tips
- Choose a flat area with no obstacles and stand close by to stop anyone wandering off.
- Offer eyes-closed instead of blindfolds and let anyone who prefers it act as a silent observer for the debrief.
- Give a time limit; frustration without a debrief teaches nothing.
Common pitfalls
- The facilitator hints at solutions, so the group never finds its own process.
- The debrief stays on the puzzle and never connects to the team's real work.
Variations
- Ask for a triangle, then a pentagon, or appoint a silent observer who reports back.
What it produces
A finished shape on the ground and a debrief on leadership, listening and decision-making that the group can link to its own work.
