What is a Game Jam?
A game jam is simply a short, creative event (often 48 hours) where developers, artists, audio makers, writers—and anyone curious—team up (or go solo) to build a small playable game around a surprise theme. It’s a friendly space to experiment, learn fast, and connect with other GameMaker and indie developers.

Understanding Game Jams
A game jam (sometimes called a 48-hour game jam) brings people together—online or in person—to create a small game in a set amount of time (24–72 hours, a weekend, or a week). The point isn’t perfection; it’s creativity, learning, collaboration, and actually finishing something. Lots of people join to try a new tool, practice design, or just have fun making something playful.
Time-Limited
Usually 24-72 hours of intense creative development
Global Events
Usually held online with thousands of participants
Learning & Innovation
A platform for experimenting with new ideas and technologies
The History of Game Jams
Game jams started in the early 2000s as small, informal meetups. As indie development grew, so did the format. Now events like Ludum Dare, Global Game Jam, and the gm(48) GameMaker game jam welcome thousands of people of all skill levels. Over time the community has figured out better theme voting, scope control, rapid prototyping, and healthy feedback habits.
Game Jam Format and Structure
The game jam format is usually: theme reveal → quick brainstorming → get the core loop working → add just enough content → polish → submit. Some jams allow any engine; others (like the gm(48)) center on GameMaker Studio 2 so people can share engine‑specific tips. After submission there’s often a relaxed feedback or rating phase where you learn what resonated.
Benefits of Participating in Game Jams
Some core game jam benefits: you learn by doing, try creative risks without pressure, build portfolio pieces, and get real feedback. The deadline keeps things small and finishable—often leading to playful mechanics you’d never plan in a long project.
Rapid Skill Development
Learn game development, programming, production discipline, and design through intense hands‑on iteration. Time pressure forces prioritization of a minimal, fun core loop.
Community Building
Connect with diverse creators, share techniques, form teams, and build long‑term indie network relationships that extend beyond a single weekend.
Creative Innovation
Safely experiment with new mechanics, art styles, pipelines, shaders, narrative structures, or accessibility features without the pressure of long production cycles.
Portfolio Building
Produce a finished vertical slice or micro‑game demonstrating execution. Each submission evidences scope control and shipping ability—key portfolio signals.
Constructive Feedback
Gather structured feedback (ratings, comments, UX observations) that informs future balancing, onboarding, and accessibility improvements.
Finishing Projects
Deadlines teach ruthless scope management. Many developers finish more complete games via jams than long unbounded solo efforts.
The gm(48) GameMaker Game Jam
The gm(48) is a quarterly 48-hour game jam exclusively for GameMaker developers. The long-standing supportive community welcomes creators of all skill levels, from beginners to experts, fostering an environment of learning, creativity, and collaboration.
Thinking about joining a GameMaker game jam? The next gm(48) starts on January 17. You can learn a ton, meet friendly people, and maybe even pick up a prize. Peek at the upcoming game jam schedule or explore past game jams to see what others finished.
Game Jam Challenges
Game jams are fun—but the clock, scope creep, tech hurdles, and team coordination can still be tricky. A simple plan, version control, and remembering to rest make the whole experience smoother (and more enjoyable).
Time Pressure
The time frame can be stressful, and participants may need to work long hours or sacrifice sleep to complete their games on time. Proper planning and scope management are essential.
Scope Management
Learning to scope appropriately for the time limit is crucial. Many first-time participants attempt projects that are too ambitious for the timeframe.
Technical Challenges
Working with unfamiliar tools or attempting new techniques under pressure can lead to technical difficulties that eat into development time.
Team Coordination
For team participants, coordinating work, managing different time zones, and maintaining clear communication can be challenging but rewarding.
Even with the challenges, the loop of theme → build → refine → share → feedback is a friendly fast‑track for improving design instincts, shipping something small, and feeling part of a welcoming community.
