What is the gm(48)?
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 from scratch in the 48 hours from when the game jam starts to when it ends.
Before the deadline is reached, you must submit your game to the website. You'll need an account on the website in order to do that.
You don't have to register or sign up before the game jam starts.
Check out our Quick Guide for more information.
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.
The GM48 is the perfect way for me to rekindle my love for game making. Every time I participate I can see a gradual improvement in my abilities and quality of my games.
In my project Countdown is a project in which I have not put all my work, but in The Legend of Princess Kidnap yes. I hope you like it
Hey look. I actually finished something for once.
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 hear many game maker devs talking about gm48 so I decided to try it out myself and it was really fun it pushed me to my limits and made me create new techniques
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 jam was a fun experience, and I look forward to the next GM48!
Excellent game jam for any skill level! This jam really brings out the best in people and allows everyone, including myself, to grow their game development skills! I cannot wait for the next one.
It's always a challenge to create something in such a short time but one of the most useful aspects of the game jam is the feedback. Often the feedback will highlight something positive or areas of improvement which gives you direction and snaps you out of the bubble you are in.
Was very fun and learned a lot about common mistakes I make
Great way to practice your skills. Creativity through restriction is a great way to come up with good ideas.
The reviews are also good and give fair criticism that helps you improve.
No matter your skill level with gamemaker, gm48 is great. It was my first game jam ever and I don't regret it at all, the feeling of community, simple website and rules, all lead to a wonderful and inspiring experience.

What would you develop?
It's never too late to get started with GameMaker Studio 2. Your next game could be one of these, so why not book a weekend for the game jam and see what you would create from scratch.
Use the game jam as a way to spark an idea from nothing to a playable prototype. Many developers use game jams to let loose their creativity and design crazy fun games.
Papers & Dragons
Dragons are papers natural enemy, as they get on fire so easily. So archers and knight is saving kingdom from them!
Why Game Jams
Game jams are community events about making games set around a given theme within a time limit. By way of these constraints, your creativity and skill will be laser-focused on creating a game from nothing to something playable, and you gaining a ton of experience with your tools and constructive critcism from your fellow developers.
Don't get discouraged! Game jams can seem intimidating, and if they do, that's a good thing. That intimation will force you to work harder at becoming better. Watch this video by Shaun Spalding for tips on how to survive your first game jam. By the way, Shaun's game PokeyPoke was originally submitted to the 25th gm(48).
Why GameMaker Studio 2

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.
