We picked up this idea from one of our music friends this summer. First thing in the morning, the students were all given slips of paper. Eight of them were the "Spies", the other seventeen were the "Resistance". The idea of the game is that no one knows who the spies are except the spies themselves. They also know the identities of the other spies. The Resistance tries to guess who all the Spies are before the Spies have voted all of them out of the game. At the end of the day the Resistance had identified all eight spies in eight guesses (they were a little too obvious), and the Spies had voted out eight of the Resistance members. So, Spies - 0, Resistance - 9. The Resistance easily won. It was a very suspicious day.
