Game Jams

Game jams compress game development into intense bursts of creativity, typically 24 to 72 hours. Participants work alone or in small teams to create playable games around announced themes. The format strips away perfectionism and overthinking, producing raw, experimental work that often influences mainstream design.

What a jam is for

The output is not the point. Asked what jams do, participants in Edge’s 2013 feature answer with completion:

One of the strengths of game jams is that they motivate developers to actually finish a project. That helps a lot of people, since they fall into a trap of not ever finishing a thing, or even starting a thing.

And with volume. “I have dozens of game prototypes that I’ve produced from jams, and I think that body of work is necessary for finding a style that suits you” — because at 48 hours, “you don’t give a shit about polish”. The pull-quote in the feature: “Jams are about volume, about making a volume of work to hone your skillset and craft.”

Scale


Ludum Dare, 2013	“after 11 years and 26 events… perhaps the bestknown game jam in the world”; “thousands of games per event”
Global Game Jam, founded 2008	16,705 developers from 63 countries at the 2013 event

⚠ And it is not only an indie practice. “It’s not just the indies: game jams are” run inside large studios too, which “host their own in a bid to kickstart fresh projects.”

One detail about how the institution came to exist: Ludum Dare got “a proper home on the web” because Phil Hassey decided it should. In a colleague’s account: “Phil was like, ‘Dude, I want to do this. I want this to keep going, because this is important.’”
