Equipment / Materials Needed
None

This game needs no materials. Just a group of players and a space where everyone can move safely.


Setup Instructions

  1. Choose a leader to run the game.
  2. Gather all players in one open area.
  3. Make sure everyone can hear the leader.
  4. Remind players they will be moving and talking in small groups.

Game Play Instructions

  1. The leader explains the goal: to form small groups and find something everyone in the group has in common.
  2. The leader calls out a number between 3 and 6. That is the size of group players must form.
  3. Players quickly move and form groups of the correct size.
  4. Each group has 15 seconds to find one thing they all have in common. It must be clear and true. Examples: “We all have glasses” or “We all like pizza.”
  5. When the 15 seconds are up, there is no more talking. Groups must stay silent until it’s time to share.
  6. One at a time, each group shares its common trait.
  7. To earn a point, a group must:
    • Have the correct number of people
    • Stay silent after time is up
    • Share a common trait that is not repeated by other groups
    • Choose a clear and real commonality
    • Have every group member agree and fit the commonality
  8. Play several rounds with the leader calling out different group sizes.
  9. To keep things fun, the leader can sometimes call a silly number, like 7 or 4½.
  10. At the end, the player or team with the most points wins.

Extra Tips and Variations

  • For large groups, add a rule that players can’t be in a group with someone they were with in the last round.
  • To add a challenge, set the timer for only 10 seconds.
  • For fun, let the group with the most creative commonality win a bonus point.
  • Always make sure the space is safe to move around. No running or pushing.
  • This game works best when everyone plays with kindness and includes others.
