MAKE A PAIR: The boy or the girl is blindfolded and led to the center of the room (hall). He/she is a leader. Any player takes a little bell and pass by him/her with it. The leader's task is to choose a partner for dance at random. If the leader (girl) chooses a girl, the latter becomes the leader. If the leader (girl) chooses a boy, they both make a pair for a dance. The fillet is given to the other person, chosen with the help of the reckoning. This game continues until there are 10-12 pairs. After that the master of ceremonies announces the pair dance.
