This is a great game to get people moving and find new things that people have in common while thinking creatively.

Begin by telling people to get into groups of three. Tell them they have two minutes to find five things that they all have in common. (You could make it harder by ruling out obvious things like clothing, gender, skin color, etc.). After a couple minutes have passed, have each group find a new group to combine with. Have each original group share their commonalities before giving the newly combined group two more minutes to find three things that everyone has in common. (These new commonalities must be things that neither group shared from the first round). After the two minutes are over, repeat this until the entire group has merged together. As a whole group, everyone should search for at least one thing that they all have in common.
