Twelve Bits: UWT Code Puzzle

Choose this exercise

Purpose: Solve a deduction puzzle where the problem statement and constraints are scattered across individual verbal clues.

Use it when: Use when examining how a team organizes fragmented verbal data, tests assumptions, and verifies constraints before reaching consensus.

Skip it when: Skip when the group needs an open-ended strategic discussion or when participants cannot communicate via clear audio or text transcription.

Group arrangement: Single team of 4 to 12 participants seated a short distance apart.

Timing: Playmeo suggests 30 to 40 minutes; 30 minutes provides 3 minutes briefing, 20 minutes solving, and 7 minutes debrief.

Materials and tools

• One set of 12 printed clue slips cut apart from the participant materials
• Facilitator answer key
• Scratch paper and pens for participant notes
• Countdown timer

Before participants arrive

1. Print the 12 clue slips and cut them into separate slips.
2. Place scratch paper and pens within reach of the group.
3. Arrange chairs in a circle spaced so people cannot read neighbors' slips.
4. Ensure the facilitator has the answer key hidden from participant view.

Say this to open

You have a collective puzzle to solve. I will hand out twelve clue slips across the group. Every slip must remain in play. You may read your clues out loud as often as you want, but you must never show or display your slip to anyone. All the information you need is on these slips. Your first job is to discover what the problem actually is. Your second job is to solve it within twenty minutes. You may begin.

How to run it

1. Brief and distribute slips 3 minutes

   Distribute all 12 slips among the participants. For 12 people, give 1 each. For smaller groups, distribute multiple slips until none remain (for example, 3 slips each for 4 people; 2 slips each for 6 people; 6 people get 2 and 1 person gets 0 is not allowed, distribute 2 to five people and 1 to two people for 7). Speak the opening script verbatim. Do not name the code puzzle or reveal the objective.

2. Discover the problem and solve 20 minutes

   Start the 20-minute timer. Participants read their clues aloud, discover that Clue 1 defines the objective (finding a four-digit access code), pool constraints, take notes on scratch paper, and test deductions. Step in only to enforce that slips remain hidden. Stop when the team submits an agreed four-digit code or when the timer expires.

3. Verify answer and debrief 7 minutes

   Confirm the final answer against the key (2531). If incorrect, explain which constraints failed. Select 2 or 3 debrief questions and invite 3 to 4 participants to comment on their information-sharing process.

Debrief questions

• How quickly did the team realize what the actual problem was, and which clue provided that breakthrough?
• What system did you use to make sure all twelve clues were heard and satisfied?
• Which constraint or assumption caused the most friction or confusion while testing numbers?

Finished output: A group-agreed four-digit code verified against the facilitator answer key.

Remote

Send each participant their assigned clue texts via private chat message before starting. All twelve clues must be distributed. Participants read their clues aloud in the shared voice meeting. Participants may use a collaborative shared text document to write down clues and test ideas. Clue text may never be pasted directly from the chat.

Hybrid

Hand printed slips to in-person participants and send private direct messages to remote participants. Distribute all 12 clues. Use an open room microphone so remote participants hear spoken clues clearly. Keep notes on a shared digital whiteboard visible to the room and remote screens.

Access and participation choices

• Provide large-print slips on request.
• A participant who prefers not to read aloud may designate a partner or the facilitator to read their slip aloud verbatim on request without disclosure.
• Participants may take private scratch notes or opt out of verbal synthesis while remaining a clue holder.

If the session gets stuck

A participant holds up their clue slip to show others.

Intervene immediately and remind the group: slips must stay face down or private. All information sharing must be spoken aloud.

The group spends ten minutes talking aimlessly without discovering the objective.

Ask: 'Has every single clue slip been read aloud to the full room at least once?'

Someone wants to pass and avoid speaking.

Do not remove their slip from play. Allow them to hand their slip to a designated peer or the facilitator to read aloud for them.
