Works with Claude, ChatGPT, Gemini, or your own local model: paste this prompt and your AI will co-facilitate this exercise with you.

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.

# Traffic Jam

Two teams of four face each other on a line of nine floor markers with an empty center space. They must swap places using only single steps forward or hops over one opposing player.

**Time:** 25 minutes. Playmeo documents a 15 to 30 minute band; 25 minutes allows briefing, multiple attempts, and debrief.
**People:** 8 to 24. Parallel tracks of 8 active movers on 9 markers each, with extra members acting as track strategists.

## Choose this exercise

**Purpose:** Observe how a team tests assumptions, coordinates systematic trial and error, and recovers from deadlocks under rigid operational rules.
**Use it when:** Use when a team needs to examine communication dynamics, systematic planning, and response to failure during a shared task.
**Skip it when:** Skip when participants cannot comfortably stand or step repeatedly, or when the group seeks an open-ended dialogue rather than a deterministic logic puzzle.

## Materials and tools

- 9 floor markers (rubber spots, paper plates, or tape squares) per track of 8 movers
- Scratch paper and pens for optional strategists

## Before participants arrive

1. Place 9 floor markers in a straight line, spaced about 60 cm apart.
2. For groups larger than 8, set up identical parallel tracks (for example, 2 tracks for 16 participants, 3 tracks for 24 participants).

## Say this to open

In front of you is a line of nine spaces with eight people on them, leaving the middle space open. Your goal is to exchange sides completely so Team A stands on Team B's spots and Team B stands on Team A's spots, with everyone facing outward. Here are your movement rules: one person moves at a time; you may step forward into an open space directly in front of you; you may jump around one person facing you if there is an open space right behind them. Backward moves are not allowed, and you cannot jump around someone who is facing away from you. If you reach a dead end, reset to the starting spots.

## How to run it

### 1. Brief and assign tracks (4 minutes)

Form groups of 8 per track. If group size is not a multiple of 8, assign extra members as strategists beside the line. Position 4 movers on spots 1 to 4 facing center, leave spot 5 open, and position 4 movers on spots 6 to 9 facing center. Explain the movement rules and walk through one legal forward step and one legal hop.

### 2. Run initial attempts (8 minutes)

Teams begin testing moves. Enforce all constraints: no stepping backward, no jumping over someone facing the same way, and no jumping two people at once. When no legal move remains, call a deadlock and have the group reset to the starting line.

### 3. Refine strategy and solve (8 minutes)

Teams continue attempts. Strategists may use scratch paper to record successful move patterns. If a team solves the puzzle before time expires, ask them to repeat the full sequence without a single reset or coach an unsolved track.

### 4. Debrief the system (5 minutes)

Gather the whole group. Ask 2 or 3 participants to answer debrief questions about deadlock prevention, decision-making, and communication.


## Debrief questions

- What pattern or rule did your team discover that prevented a complete deadlock?
- How did your group decide who made the next move when several people had conflicting ideas?
- When the puzzle locked up, how did the team handle resetting and starting over?

**Finished output:** Completion of the puzzle with both teams swapped, or a recorded sequence of moves attempted.

## Remote

This physical exercise relies directly on body orientation and physical spacing. It cannot run online as a physical game without becoming a different method. For online groups, run a separate digital puzzle such as a virtual peg-solitaire or coin-sliding board.

## Hybrid

Hybrid delivery is not recommended because remote members cannot share the physical line or spatial orientation. If required, remote members join as vocal strategists via room speakerphone to advise an in-person track, while in-person members report the board status verbally after each move.

## Access and participation choices

- Participants may choose the role of track strategist or move recorder, remaining seated with scratch paper rather than standing or stepping on the markers.
- Any participant may pass on physical movement without disclosing reasons.

## If the session gets stuck

**Participants accidentally step backward when realizing an error.**

Remind everyone that backward moves are not allowed. Declare an immediate reset so the team learns the cost of an illegal step.

**One dominant mover dictates every step while others disengage.**

Pause the attempt and instruct the team that each person must verbally declare their own intended move before stepping.

**The team hits the same deadlock repeatedly.**

Provide a structural clue: avoid placing two people facing the same direction directly adjacent to each other until the alternating pattern requires it.


## Terms used here

- Deadlock: A state where no legal forward slide or hop exists for any player on the track.
- Hop: Moving around one person who is facing you into the single open space directly behind them.

## Sources and adaptation

Observed in Playmeo documentation, where Mark Collard is listed for the activity write-up. The mechanic derives from the classic frogs-and-toads logic puzzle.

Retained the 8-player setup, 9 spots, and movement constraints from the Playmeo documentation. Clarified rules phrasing in opening script, streamlined materials, specified role options for uneven numbers, and added timing structure.
