The gm(48) is a quarterly 48 hours GameMaker game jam from the community of /r/GameMaker.

For more than 5 years, the community has been running the gm(48) games development competition for game developers of all ages and abilities. Whether you are a beginner or an expert, young or old, there's no reason not to participate. The gm(48) is a casual, fun and learning experience for everyone. By participating in the gm(48), you will learn and grow as a GameMaker developer. If you don't believe us, read the testimonials from those who participated.

The organizers constantly strive to further improve the gm(48) by enhancing the user experience, writing detailed guides and tutorials, and figuring out new ways to encourage community involvement and contribution. We recently redid our entire website, which serves as a symbol of our dedication, and intention to further expand the game jam. In addition, we provide game jam wide statistics and analytics, open for everyone at no charge. We believe this gives valuable insight into how developers use GameMaker. If you have a question, then check out our answers to frequently asked questions, or send us a message.

Thank you for taking the time to check out our game jam, and we hope to see you participate!
