A crowd game is a warm-up instrument. Put it in the wrong slot and it works against the thing it was supposed to help.

The slot that works

Immediately before something that needs a receptive room — a keynote, an announcement, the second half after a break.

The mechanism is simple: the audience finishes physically moved, aware of the people around them, and looking at the screen. Whoever walks on next inherits all of that. Waste ninety seconds on housekeeping in between and they inherit none of it.

Slots that do not work

Straight after lunch. A room that has just eaten will comply and will not commit, and half-hearted participation is worse than none — the result on screen looks broken and the room concludes the thing does not work.

As the opener, cold. Before anyone has settled or heard a voice they trust, you are asking strangers to do something physical on the word of someone they have not met. The awkward gap gets much longer.

End of day. People are calculating their exit. Anything that looks like it might extend the schedule is resented.

After anything serious. Obvious in principle, missed in practice when the running order shifts on the day.

Length

Two to four minutes. Long enough to get past the initial hesitation and into the part where people coordinate; short enough that it ends while the room still wishes it had not.

Past five minutes it stops being a moment and becomes an item, and the audience starts wondering how long this is going on for.

Who has the microphone

The largest single variable, and it is not technical.

A host who asks plainly, once, and then holds the silence gets a room in about twenty seconds. A host who hedges, repeats themselves, or apologises for the activity gives everyone permission not to bother. No amount of engineering compensates.

If the run of show has nobody willing to stand up and mean it, that is the thing to fix first.

Practical notes

  • Put housekeeping before the activity, never after.
  • Brief a handful of people scattered through the room to move immediately. It is the single most effective intervention available and it costs nothing.
  • Agree in advance who is talking while it runs. Silence during a crowd game is much longer than it sounds from the stage.
  • Have an ending. “That’ll do, sit down” is an ending. Letting it trail off is not.
