For 11 or more players (odd numbers)
One player is chosen to stand in the centre, everybody else partners up and stand in a large circle with their partners next to them so they and their partners are face-to-face.
The player in the middle calls out commands such as “face to face,” “back to back,” “side to side,”. Players take these positions accordingly. When the person in the middle calls “All change”, all the players have to find a new partner during which the person in the middle tries to get a partner. If they are successful the person left without a partner becomes the new person in the middle and starts to give commands.
Suggestion: If the group is larger than 50, you might want to consider breaking it into two or more circles
