Everyone playing needs to know each other quite well. To start the game everyone is blindfolded. The leader will then take a player, sometimes more than once and move them around the room, so they don"t know where they are or with whom. When the leader is finished moving people. Everyone playing will be facing someone. Everyone then sits down on the floor. The leader will then randomly select a player and tap them on the shoulder. This person may remove their blindfold. It needs to end up with half the group blindfolded and half not. When told to start those who are wearing blindfolds must try to identify who is opposite them. The player opposite them replies by tapping on the floor. One tap for yes, two for no. The blindfolded player has to ask questions such as, "Do you have black hair" they can't ask things like "is your name Sophie" Once the blindfolded player thinks they know who it is she puts her hand up. The leader then will come to her and asks "Who is opposite you?" If they are correct they may remove their blindfold. Play continues until everyone blindfolded has guessed who is opposite them.
