Global Game Jam

The Global Game Jam (GGJ) is an annual distributed game jam. Inspired by the Nordic Game Jam, and created by Susan Gold, Ian Schreiber, Gorm Lai and Foaad Khosmood, originally developed under the International Game Developers Association Education SIG to bring together the elements of creativity, collaboration and experimentation. At each site, participants gather to develop ideas, form small groups, create new, creative, innovative games, and present them to their peers and the global community, all in a limited time span. As of 2013, GGJ is managed by Global Game Jam Incorporated. Current and past board directors include the founders Elonka Dunin, Lindsay Grace and Zuraida Buter. 2022 staff members are Executive Director Tim Cullings, Director of Operations Charly Harbord, and Senior Director of Communications Tarja Porkka-Kontturi

In January 2019, GGJ generated teams in 860 sites in 113 countries, who over the course of one weekend created 9,010 games. The Global Game Jam carries a registered trademark.

In January 2022, GGJ lasted 10 days and nights and was the longest jam in organization's 14-year history. 33,000 jammers registered at 680 sites in 100 countries.

Participants
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.
