The game jam for every type of GameMaker developer
The gm(48) is a quarterly community event centered around a competition, in which game developers, by themselves solo or in teams, must develop a game in GameMaker Studio 2 in 48 hours.
These competitions are commonly referred to as game jams. Once the games have been submitted, everyone will play, rate and critique the submissions for two weeks, the ratings from which the top three games will receive licenses to GameMaker Studio 2 as prizes.
The game jam is open to GameMaker Studio 2 developers of all ages, abilities and backgrounds. Beginner or expert, young or old, artist or programmer, all are welcome in the gm(48) game jam community.
In a limited sense, yes.
You are permitted to start pre-production, which we consider to be brainstorming, storyboarding, game design document, etc, of your game before the game jam starts. You can't start production of any assets or do any coding. Even art sketches can be considered cheating.
You participate by creating a game in GameMaker within the 48 hours from when the game jam starts to when it ends.
Before the deadline is reached, you submit your game to the website and add information about how to play, artist and programmer credits as well any known issues.
You don't have to register or sign up before the game jam starts and the game jam is open to GameMaker Studio 2 developers of all ages, abilities and backgrounds. Beginner or expert, young or old, artist or programmer, all are welcome.
We've collected all information in a nifty game jam guide for you to read.
No, but many developers use the GameMaker project files to learn from, so we encourage you to upload your project, however "gross" it might be. Let's be honest, everyone's project is spaghetti code after 48 hours.
As thanks for giving back to the community, you'll get an achievement for uploading your project to your entry.
The score is calculated using the Bayesian average method. This means that a game with one 100% rating can't score higher than a game with five 80% ratings. In other words, the number of ratings a game has received plays a role in calculating the score. That's why the averages in the rating categories doesn't match up with the final score.
Yes, you fully own the rights to your game. We reserve the right to use your game for promotional purposes. We can't steal or sell your game. → Terms and Conditions
Submit your post-jam game to GX Corner (GXC). GXC is a collaboration between YoYo Games and Opera to bring together a brand new platform for Opera GX users to play, share and discover games made by independent GameMaker developers, such as yourself. → Learn more
Hear it from participants
With over 2000 participants to date, the gm(48) game jam has for years been instrumental in enabling developers to become better at game design, game development and GameMaker Studio 2.
That's a nice way to learn and develop games with originally! even if you are a beginner, with GameMaker Studio is truly easy to make games in such as short period of time!
Some of the most fun and engaging game developing experiences I've ever had have been during my participation in GM(48).
I encourage all GameMaker enthusiasts to give it a go.
This project was a lot of fun. I streamed a good majority of my development and had a lot of fun doing so. The drive and push it gives you to make a full, complete project is very valuable.
Whether you're looking for a tight-knit community, putting your abilities to the test, or simply scratching that game development itch, the GM48 is the definitive GameMaker experience.
This platform is great for seeing what is possible in 48 hours. Making Color Pickers help point out some issues I run into when making games.
I'm sweating. I learned a lot in such a short amount of time (especially about time management). The 29th GM48 was my first jam and I'm happy with what I produced.
We all start somewhere and I'm so grateful for this opportunity.
GM48 was my first Game Jam. It was a really awesome first experience. The Game Jam is really neat with nice theme. Will sure participate to the next GM48!
Joining gm(48) has been a great experience.
I think Simon Milfred and I make a robust team and we have so much fun.
Will do it again!
I usually join Ludum Dare and other local jams, but I believe that GM48 are the ones I enjoy most.
It's a way to see what someone can do in just 48 hours with Game Maker, and the source code is usually available to mess with and to learn about.
Really fun Jam with a great community.
I've done this a couple times now, and each time is more fun than the last. It's cool seeing how I've improved since I started, and overall participating has been a great deal of fun!
This is a fun game jam with a great community.

Why Game Jams
During a game jam, participants are challenged to create games within a deadline while adhering to a community-voted theme. The constraints will enable you to focus your creativity and game developer skills on creating a playable game from scratch, gaining valuable experience with GameMaker Studio 2 and constructive criticism from your fellow game developers.
Be persistent and don't give up! Taking part in a game jam can seem intimidating, but that's a good thing. It will force you to work harder to improve your skills. Watch this video by Shaun Spalding for tips on how to survive your first game jam. The original version of Shaun's game PokeyPoke was first submitted to the 25th gm(48).
Why GameMaker Studio 2
Making games development accessible to everyone means taking away the barriers to getting started. GameMaker has everything you need to take your idea from concept to finished game.
Using the intuitive 'Drag and Drop' development environment you can have your game up and running in a matter of minutes without ever having to write any code! GameMaker's built-in language (GML) helps you learn to program as you go and not jump in at the deep end of coding.
GameMaker Studio 2 is simply perfect for game jams.
