Participants in the Global Game Jam are of all skill levels and in various fields. Everyone from professional game developers to educators to artists and designers is welcome to participate. Once the jam begins, participants come up with game ideas, before pitching those ideas to each other and forming teams to work together on a project.
Event organization
Groups wishing to host a jam site must fulfill certain requirements. Their location must have Internet access for everyone involved, access to development resources such as an IDE, possibly preinstalled at the location, an event coordinator, beverages and nearby food access, if possible, round-the-clock availability of the location, and security for belongings. At each site, the Global Game Jam runs continuously for 48 hours in each time zone, beginning at 5:00 PM on the start date, and ending at 5:00 PM two days later. The recommended schedule includes a short planning and team creation period, followed by development time until 3:00 PM on the final day. The last few hours are set aside for teams to present their creation to each other. However, sites are not required to follow this schedule. At the beginning of the event participants are given a theme, such as “Extinction” in the 2011 Jam. Participants are asked to create a game that in some way relates to this theme. Additionally, participants are given a list of “achievements”, also referred to as diversifiers. These are designed to drive creative development by adding a unique or limiting factor to their game’s design.
