The group stands in a circle. One person volunteers to be the detective and leaves the room. One person then volunteers to become the group leader who will initiate a movement and continually change the movement with the rest of the group following the lead. The group is asked not to look directly at the leader as it is the detective’s job to walk around inside the circle and find out who is leading the movement. The leader should change the movement regularly so the group is not stuck in doing the same thing too long, making it impossible for the detective to do his/her job. As soon as the detective discovers who the leader is or after a maximum of 3 guesses a new detective and leader are picked.
