"Jam" is a reference to musician jam sessions. The goal is to come together and make a videogame, or non-digital game like a board game or card game. Participants rapidly prototype game designs and hopefully inject new ideas to help grow the game industry. We share a common theme and constraints. We ask participants to create a game from beginning to end in a prescribed time (maximum of 48 hours). The brief time span is meant to help encourage creative thinking to result in small but innovative and experimental games.
