Just what is a game jam? It is a short event, usually only a day or two, where game developers plan, design and create a short game. Similar to a music jam session, game jams don't involve much pre-planning and rely on immediate idea generation and improvisation. Game design companies have these jam sessions regularly, and while many of the games that happen here are digital, some are paper-based. They usually occur in one physical location to allow for immediate, organic collaboration. While there is an element of competition, most of the work is focused on collaboration towards a common goal.
