Global Game Jam (GGJ) is the world's largest game jam community, bringing together developers of all skill levels across 100+ countries to create games collaboratively over 48 hours. Since its founding in 2008, more than 507,000 jammers have created over 110,000 games.
Participants join a local jam site (hosted by universities, studios, makerspaces, and community organizations) or jam online. The global theme is revealed before the local sessions; teams typically have 48 hours at their selected site to design and build a game. There are no prizes — the focus is on creativity, learning, and community. Games are published through GGJ under its submission and archive policies.
The 2027 jam runs January 25–31. Site host registration opens November 1, 2026; individual jammer registration opens December 1, 2026. Visit globalgamejam.org to find a site near you or to learn about hosting your own.
2027 check, November 4, 2026: The official homepage was directly inaccessible (403), but its current official indexed text confirms January 25–31, 2027, November 1, 2026 host opening and December 1 jammer opening. The official annual announcement separately lists January 18–22 prep week and January 24 theme reveal. The January 25–31 dates are a global window; participants follow their chosen site’s actual session and registration deadline.
Age access and cost are local conditions. For example, the official historical Singapore 2026 listing describes no entrance fee but limits participation to 18+ or 16+ with guardian consent; the Yogyakarta 2026 listing instead lists a Rp. 65,000 charge and a 14+ restriction. These examples show why a universal zero fee or unrestricted all-age entry should not be assumed; they are not promises of 2027 site prices or eligibility.
