Each year Pheno invites respected designers to present bespoke single-session games: a trio of more serious games (the Triptych) and a duet of lighter, more humorous games (the Diptych).

These games have tended to be system-light (emphasising characterisation and drama over rules use and tactical simulation), and showcase what we consider the best of Pheno roleplaying: characterisation, genre, entertainment, innovation.

Players and teams can enter each game by itself and the games will be judged separately, but complete teams finishing all three games of the Triptych will also be eligible for the Triptych Perpetual Trophy. Teams finishing both Diptych games will be eligible for the Diptych Perpetual Trophy.
