Help me prepare and run the exercise below. First ask for my participant count, time, setting, access needs and intended result. Check these against the stated limits. Use the supplied rules and materials. Explain any proposed changes before using them, and label them as adaptations. Do not invent source claims or require personal disclosure. Give me one step at a time when I say start. I manage the people, physical activity and clock; do not claim to observe the room. Ask me what happened before choosing a next step.

# Jigsaw Puzzle Mingler

Participants receive marked jigsaw puzzle pieces, mingle to find matching edges, and bring connected sections to a central assembly table.

**Time:** 15 minutes. UWT standard 15-minute plan based on the 5 to 15 minute icebreaker window in source records.
**People:** 4 to 24. Individual mingling into spontaneous pairs and small clusters, finishing at a central table.

## Choose this exercise

**Purpose:** Prompt brief one-on-one introductions across a room through physical piece-matching.
**Use it when:** Use during an event opening or scheduled break when participants need a concrete, low-pressure reason to talk to people outside their immediate circle.
**Skip it when:** Skip when the meeting is strictly seated, when floor mobility is constrained, or when the group must start directly on serious agenda items.

## Materials and tools

- One physical jigsaw puzzle (total pieces scaled to roughly 1 to 3 times the participant count, such as 12 to 24 pieces for 4 to 8 people, or 24 to 60 pieces for 12 to 24 people)
- One fine-point permanent marker per 4 participants
- One central assembly table with a clear, flat surface
- One puzzle box lid or printout showing the target image displayed at the table
- Digital whiteboard platform with pre-sliced numbered image tiles (if running remote)
- Webcam focused on the physical table, projector, and screen (if running hybrid)

## Before participants arrive

1. Select a puzzle whose total piece count equals roughly 1 to 3 pieces per expected participant.
2. Clear a central table for assembling the puzzle and prop up the reference image.
3. Distribute markers around the room and hand 1 to 3 random puzzle pieces to each person as they arrive.

## Say this to open

Welcome. Each of you holds one, two, or three puzzle pieces. First, turn your pieces over and write your first name on the back. When I give the signal, stand up, mingle, and compare your pieces with others. When pieces match, introduce yourselves, exchange names, and keep mingling until we gather at the central table to complete the picture.

## How to run it

### 1. Label puzzle pieces (2 minutes)

Participants write their first name on the back of each piece they hold. Ensure everyone has at least one piece. Anyone who prefers not to write their name may draw a personal symbol or initials.

### 2. Mingle and test fits (7 minutes)

Participants circulate, compare edges and colors, and test connections. When pieces lock together, holders introduce themselves and state their name and current project. They continue mingling to grow clusters until the facilitator signals the table phase.

### 3. Assemble at the central table (3 minutes)

Participants bring matching pairs and clusters to the central table. They place pieces into the master board using the reference image. Participants with unmatched pieces test them against the growing board.

### 4. Reflect and review (3 minutes)

Gather the room around the central table or back in seats. Facilitator poses debrief questions to close the exercise. Take two or three quick observations from the room.


## Debrief questions

- How did you decide whom to approach first when searching for matches?
- What visual clues helped you locate connecting pieces across the room?

**Finished output:** A partially or fully assembled jigsaw puzzle on the central table with participant names on the underside of placed pieces.

## Remote

Run an online version using a shared digital whiteboard. Pre-slice an image into numbered rectangular tiles scattered across the canvas. Assign 1 or 2 tile numbers to each attendee. Run 4-minute breakout pairs where partners examine their tiles and compare border markings. Return to the main canvas where attendees drag their tiles into position on a master grid.

## Hybrid

Physical attendees work with physical puzzle pieces while remote attendees join via video call. A dedicated webcam points directly down at the central table. A facilitator or dedicated assistant operates the physical board on behalf of remote participants, who unmute or use chat to direct where their assigned physical pieces should be placed.

## Access and participation choices

- Participants with limited mobility may sit at the central assembly table as table coordinators who test incoming pieces from minglers.
- Anyone may choose to observe, hold a piece for someone else, or decline active mingling without explanation.

## If the session gets stuck

**Participants focus entirely on solving the puzzle in silence without introducing themselves.**

Prompt the room aloud to exchange names and current roles before testing their pieces.

**The puzzle is overly complex or has large solid-color zones that stall mingling.**

Point people toward the reference image at the central table and advise them to prioritize outer edge pieces first.


## Terms used here

- Edge piece: A puzzle piece with at least one straight side, typically forming the outer border of the puzzle.

## Sources and adaptation

Observed in Teampedia entry 'Jigsaw Puzzle' (last modified 2014) and SessionLab method directory. Original creator is uncredited in available records.

Retained the core mechanic from Teampedia of writing names on puzzle pieces, mingling to find matching edges, and moving connected sections to a central table. Added structured step timings, explicit group size boundaries (4 to 24), a scripted introduction, role adaptations for seated participants, and structured debrief questions missing from the source wiki page.
