What is the gm(48)?

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, artist or programmer, there's simply no reason not to participate. The gm(48) is a casual, fun and learning experience for everyone involved.

Did you know that 676 games have been submitted to the gm(48) so far? It's the most popular GameMaker game jam.

How do I sign up?

All you have to do to participate is register an account on the website. You can register at any time, and it's completely free.

When the game jam starts, you create your game. When it ends, you submit it via the website. There's no complicated sign-up process, or requirements to enter the game jam.

Did you also know that 980 users have registered so far? Participants range from beginners to experts, from artists to programmers, and from young to old.

Okay, but there's gotta be some rules?

There is, but it's pretty simple.

The most important rules are the following 1) that your game must incorporate the theme in some way, 2) that your game must be compiled using GameMaker, and 3) that you have to create your game and its content in the 48 hours between the start and the end of the game jam.

There are a few exceptions, but these are the rules that you should keep in mind. In any case, you should really read the rules for more information.

If you have any questions regarding the rules, please take a look at our Frequently Asked Questions article. You will most likely find your answer there.

When do I get to jam?

Once the countdown on the front page reaches zero, you can start developing your game.

Create a game, submit it to the website and bam, you're done. That's it, really.

The hard part is developing the game.

So, how do I win?

That's the million dollar question!

To win the gm(48), your game must have the highest average sum of the following categories:

Art
The level of artistry in the graphics, design, and style of the artwork
Gameplay
The quality of the level design, game balance, fun, and experience
Immersion
The ability of the gameplay, story, world, and characters to engage the player

Theme

We give prizes to the top three games, so try your best!

It's okay if you don't win. You see, everyone can leave feedback for your game. That way, even if you don't win, you still have lots of feedback that you use to improve yourself and the game you made in just 48 hours.

All right, I'm ready to participate!

Awesome, we're always glad to have more developers join our community game jam!

You'll find the game jam's schedule below this panel. The game jam is organized by the community of /r/GameMaker, and we recommend subscribing to the subreddit to stay up-to-date.
