We have played this at church camp for years. It works best with fifth graders to older teenagers.
A large group of kids sit in a chair in a huge circle. A leader stands in the middle and says a statement and if its true you move the stated number of chairs to the left or the right.
For example, "If you have blue eyes move three chairs to the right." But they also can get pretty personal, "If you wet the bed as a kid move ten chairs to the left."
The catch is that if someone is sitting in the chair that you were moving to, you have to sit in their lap. Sometimes when we would play we would end up with four or five people stacked on top of each other.
This game brings a ton of laughs and you learn quirky things about each other. :)
