Players sit in a circle on the floor. Send one player away from the vicinity of these players. While he is away from others, choose a leader. The leader starts any simple movement, such as patting his stomach, opening and shutting his mouth, waving his hand, and so on. The other circle players copy his movements, changing when he does. The player who has been sent away now comes and stands in the centre of the circle. His task is to find which of the circle players is the leader. The centre player has three attempts within two minutes to find the leader.
