Separate the players into two teams. Have each team form one line. Each team chooses one player and does not reveal whom they chose. One person from each team volunteers to hold up a blanket between the two teams. The chosen players face the blanket directly.
The players who are holding the blanket should drop the blanket. The first player to name the person they are facing correctly wins. The other player is out.
Continue selecting players to represent each team and naming them until an entire team is out.
