You get a group of people. Most sit down while a few stand up and are "it" I guess you would say. The ones standing tell the other players "Heads down, thumbs up" While the players who are sitting with their hands down and thumbs up AND EYES CLOSED, the players who are "it" go around and chose a person, and lightly push or tab that persons thumb down. Once every person who is "it" taps someone's thumb, they tell every one they can look up again. Each person who felt someone touch their thumb must try to pick out which player chose them. If you choose correctly, you change places with the person who chose you, and you are now "it". If you chose incorrectly, you stay seated and that person remains "it".
