Game Jams
Creativity under constraints
Game jams challenge developers to create complete games in limited time, fostering experimentation, community building, and unexpected innovation.
Overview
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.
