Players split up into three groups of up to four players. The goal is to transform the city by dealing with its past. On a turn, a group rolls a die. By a modified roll and move mechanism, they move through the city and either answer trivia questions or debate audio files from the Pinochet era (cards offer questions for these debates). On yet other fields the groups have to deduce certain words related to history and human rights. When successful, the place a transformation marker on the field in questions. When the city has been transformed, the game ends with a victory.
