Every player is also assigned identification tags. Call upon players to come up one at a time to where the set of cards, IDs and information sheets are placed. Ask them to pick up one of the sets and instruct them to look over the sheet that has been provided and circle the numbers of players they hope to form a group with. If such groups have been formed, they identify themselves to the arbiter. It is now the responsibility of the arbiter to be alert to the formation of groups.
Players signal the others with whom they wish to form a group.
This is followed by an extensive discussion amongst themselves, which take place at the tables. Once the players who have formed a group have identified themselves, the arbiter goes up to them to check to see if they have either 3 pairs of cards or 4 of a kind. If they do, the group is identified to be a valid one and the arbiter notes it down. If the group does not have a valid card hand, the experimenter declares it invalid. If the group members do not agree on a hand, the experimenter gives them a minute or so, to get their story straight and in the absence of an acceptable argument, declares the group invalid.
