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 types. 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.

No.
But many developers use the project files of submissions to learn from, so we encourage you to upload your project, however "gross" it might be. Because, let's be honest, everyone's project is spaghetti code after 48 hours.
You'll get an achievement for uploading your project to your entry.
The score is calculated using the Bayesian average method.
In short, this is used to prevent a game with one 100% rating scoring higher than a game with five 80% ratings.
That's why the averages in the 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.

5Drawing sprites is fun so it's a good experience. :)
5GM48's game jams are pretty challenging, as there are a lot of awesome and talented artists, designers and coders who participate in them.
5I'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!

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.

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
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.
