The game jam for every type of GameMaker developer
The gm(48) is a quarterly community event centered around a competition, in which indie 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 for free to 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.
Game and artistic content must be created within 48 hours, except for certain exempt resources that must be credited and have sufficient intellectual property rights.
These exempt resources include derivative works, widely-known free GML scripts, promotion content, generators, fonts, logos, brands, brushes, loops, drums, and instrument samples, among others.
Please refer to rule #4 for the full list.
To a certain extent, you are allowed to prepare for the game jam before it officially begins. This includes what can be referred to as pre-production, which involves brainstorming ideas, storyboarding, and creating a game design document. However, you are not allowed to begin actual production of any assets or start coding until the game jam officially begins.
It's important to note that even creating art sketches in advance could be considered cheating and is therefore prohibited. The purpose of a game jam is to challenge participants to create something new and innovative within a set time frame, and pre-production is allowed only to a certain extent to help participants plan and organize their ideas, not to give them an unfair advantage over other participants. So while you can start planning and ideating before the game jam starts, you cannot start creating any tangible assets or start coding until the official start time.
For the game jam, the game score is determined by using a statistical technique called the Bayesian average. This means that when calculating a game's score, the number of ratings it has received is taken into consideration. For instance, a game with a single 100% rating will not necessarily get a higher score than a game with multiple 80% ratings.
Basically, the Bayesian average method ensures that a game's score reflects the collective opinion of a larger number of people who have played and rated the game. So, even if a game has high ratings in one category, like graphics or sound, it may not necessarily have a high overall score if it has not received enough ratings.
This is why you may notice that the rating averages in specific categories do not always align with the game's final score. The final score is influenced by both the average rating and the number of ratings received across all categories.
Your game is your intellectual property, and rest assured that you own the rights to your creation. You have put in a lot of hard work, creativity, and dedication to bring your game to life. Your exclusive right to use, sell, and distribute your game as you see fit is acknowledged by the terms and conditions.
In recognizing the value of promoting your game and the game jam to reach a wider audience, gm48.net reserve the right to use your game for promotional purposes. This means that your game may be showcased on the website, social media platforms, or in other marketing materials to help promote your work and share it with the community.

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.
GM48 was difficult but rewarding. Two days don't seem as much time but many things can be made in this timespan.
First time in Gm48. Really tough for me and my team because we had been too ambitious and the low experience didn't help! Anyway, very funny, I will participate again.
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.
I always tend to have fun when jam season hits. Its a great chance to sit back and relax without having to stop programming or writing music or whatever. Creative freedom with minimal restrictions. It helps that GM48 is run by people who know what they're doing!
I had a perfect version at 7:00. Deadline gets extended 15 mins so I try to add one little thing to it. Fatal error on my submitted project with no way to fix one simple mistake that completely ruins an entire 48-hour slugfest BY MYSELF.
Probably won't be attending another.
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
I was used to procrastination but participating to a game jam made me feel more motivated and I nearly coded during the 48h. That was a very nice experiment !
If you want a quick break from your main project, and a dopamine hit from receiving waves of feedback from a passionate community, then the GM48 jam is for you!
I've learned a lot during GM48!
The experience has been incredibly fun and I'll definitely be joining more game jams in the future. Going through all the other entries is just as fun as making our game was!
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.
Really fun Jam with a great community.
The Jam was a lot of fun! One tip I can give to future participants: Nail down what you want to do as quickly as possible! If you don't, it might come around later and bring unwanted trouble!
