This is a game about communication without language. It is played in complete silence.
This intriguing and peculiar game is played entirely in silence. Furthermore, only the game master is allowed to write and pass notes. Many of these notes are provided in the game text for print-and-play use. The game presents a single scenario that incorporates the well-known game-theory problem of "the prisoner's dilemma". The rules suggest a post-game (verbal) analysis by the participants.
Note the game was an anonymous contribution to the Game Chef 2013 competition.
