Theme and Diversifiers


All locations all over the world share the same theme for the jam. The theme is announced at each local jam site after 5 pm local time on Friday. Timezones from New Zealand to Hawaii are all participating. As Global Game Jam aims for all jammers to have the same experience they ask everyone to keep the global theme a secret until the last region (Hawaii) starts. The theme is announced on Global Game Jam’s social media and their website after Hawaii has joined the jam.

For themes from past years, see the Global Game Jam® History.



The GGJ Diversifier list is aimed at providing an additional starting point for the game jam games. They can help you focus and choose interesting directions for your game project and add an extra challenge for the experienced jammers. The GGJ Diversifiers is a free-for-all voluntary list of secondary constraints, that the individual teams can choose to go for, or not, as they please. If they do go for one or more diversifiers, they get to tick off them as fulfilled when uploading their game. The use of the diversifiers as part of your game project is absolutely voluntary. If you are a first time team of students, we recommend that you focus primarily on the overall constraint (the theme and the time), and only add in extra diversifiers if you feel sure you will have something to hand in on Sunday.
