Values Stock Market

Choose this exercise

Purpose: Observe how competition, scarcity, and blind trades influence negotiation and decision making under time pressure.

Use it when: Use as an energetic warm up before workshops on organizational values, negotiation, or team agreements.

Skip it when: Skip when high acoustic noise or continuous milling is unsuitable, or when the group needs deep personal values reflection instead of a fast trading game.

Group arrangement: Whole group milling and trading simultaneously in open space

Timing: Playmeo records a 5 to 15 minute band; 15 minutes accommodates card distribution, rules, two rounds of play, and debrief.

Materials and tools

• Blank index cards (5 per participant)
• Pen or marker for writing values onto cards
• Timer or stopwatch

Before participants arrive

1. Count the number of participants present.
2. Select that exact number of distinct values from the sample list (for example, 8 participants need 8 distinct values).
3. Write each selected value on exactly 5 blank index cards, producing 5 cards per person (for example, 40 cards total for 8 participants).
4. Shuffle all cards together into one deck.
5. Clear an open floor space where people can walk and talk freely.

Say this to open

Each person will receive five cards facedown. Keep them secret until I say start. Your goal is to collect five cards of the exact same value. Everyone trades at the same time without taking turns. All trades are blind, meaning you cannot reveal, say, or hint at what value you hold. You can only call out the number of cards you want to swap, from one to three, repeating the number to attract a partner, like 'Two, Two, Two!' If another person calls out that same number, swap that exact number of cards facedown.

How to run it

1. Deal cards and state trading rules 3 minutes

   Deal five facedown cards to each participant. Tell everyone not to look yet. Announce the three rules: play is simultaneous, trades must be equal counts of one to three cards, and all trades are strictly blind. Give this explicit example: 'If I want to swap two cards, I call out Two, Two, Two. If Jordan also shouts Two, we meet and swap two cards facedown without speaking about the values.' Answer any questions.

2. Run first trading round 4 minutes

   Call 'Go.' Participants inspect their cards, move around the room, and call out numbers to trade facedown. Continue until someone collects five identical values and shouts 'Corner' or 'Matched.' Call 'Stop' immediately. Confirm the winning hand by checking that all five cards show the identical value name.

3. Run second trading round 3 minutes

   Collect all cards, reshuffle the entire deck, and deal five facedown cards to each person. Run a second trading round under the identical rules. Participants can test new trading speeds or strategies. Stop when a player calls out a completed set of five identical values. Verify the cards.

4. Debrief trade decisions 5 minutes

   Gather the group. Ask the debrief questions. Collect 3 to 4 observations from volunteers across the room, focusing on how people chose which values to discard and how lack of information affected their trades.

Debrief questions

• What strategy did you use to choose which values to keep and which to trade away?
• How did the rule against sharing information change how you traded?
• How did speed and scarcity affect your willingness to part with specific cards?

Finished output: At least one participant completes a verified set of five identical value cards, followed by group observations on blind trading decisions.

Remote

This activity requires simultaneous physical card handling and open-floor blind trading. It cannot be run cleanly in remote video meetings without altering the core mechanic into an entirely different software-based card tool. Deliver this exercise only in person.

Hybrid

Hybrid delivery is not viable because remote participants cannot mill, call out simultaneously, or exchange physical cards with in-person players.

Access and participation choices

• Participants with limited mobility can sit at a stationary trading desk where other traders walk to them.
• Participants who prefer to avoid loud shouting or physical milling can serve as the timekeeper and card verifier, checking hands at the close of each round.
• Any participant may opt out of active trading to observe and contribute observations during the debrief.

If the session gets stuck

Players show their cards or whisper the name of the value during negotiations.

Pause the room immediately. Remind everyone that trades must remain completely blind and players can only shout the number of cards being offered.

Two players attempt an unequal trade, such as swapping two cards for one card.

Remind players that every trade must be an exact equal count: one for one, two for two, or three for three.

Terms used here

• Blind trade: An exchange where cards are swapped facedown without either participant disclosing the words written on them.
