The game master determines the criteria according to which the people in the room should form groups.
It says for example:
Everyone will form groups,
*with the same eye color,
*who have birthdays in the same month,
*with the same number of siblings,
*the same colour of the T-shirt,
*of the same zodiac sign,
*who have birthdays in the same decade,
and so on
This warm-up game is especially suitable for groups who do not know each other very well.
Variation
The players do not form groups, but line up in a line sorted by a certain criterion, for example:
*according to the size
*according to age
*according to hair colour (light - dark)
*everyone hums any tone, then set up according to the pitch
*and so on
