Game Jam Info

Below are some frequently asked questions.
View and download the full Game Jam Guidelines here.

What is a Game Jam?

A Game Jam is essentially a hackathon for video games. It is a gathering of people for the purpose of planning, designing, and creating one or more games within a short span of time.

How Do I Submit My Game?

You can submit your game by filling out the submission form and including your BBDOC link and any other requirements mentioned in the form. Remember to submit before the end of the Game Jam.

Who can participate?

Anyone can participate in a Game Jam. Usually participants are made up of creators, artist, video game developers or players, and anyone who wants to make a game.

What is the Game Jam Theme?

The Game Jam theme is all about curing leukemia, and you can create any kind of game you want, from 3D to 2D and beyond! Your game should have a unique way of battling leukemia and should prominently feature the Cure Leukemia logo.

Who Picks the Winner?

We will collect all of your submissions and pick out the game that we think is best overall. We will factor in how well you use the theme as well as the overall design of your game in our decision. Please refer to our Guidelines PDF for more information about the assessment criteria.

Who is allowed to join? Teams or Individuals?

We welcome both! Both teams and individuals are allowed to enter. Keep in mind that a team places in the top 3, they must split up or share a prize.

Can you use Buildbox 2, Buildbox 3, BUILDBOX 4 and/or Buildbox Free?

Yes, you can use Buildbox 4, Buildbox 3, or Buildbox Classic for this game jam.

What’s the game type?

You’re free to decide the type you wish to create. As long as it’s not a direct copycat of another game and follows the rules and incorporates the theme, we’re good. We do not want to restrict your creativity so go for anything you want.

Will artwork and sounds be provided?

Nope. You are free to use whichever art or music you want as long as you have the permission to do it (you’ve purchased it or it’s licensed to you, you own it, you drew it, etc). Again, we do not want to restrict anyone’s creativity and have a bunch of games which look the same.

Can we upload a game already created if it matches the theme?

No. That would be the same as cheating. You can only start working on your game once the jam has started.

Where are updates about the Game Jam located?

We will be announcing the theme and other updates on Facebook, Instagram, Twitter, LinkedIn, Email, Youtube, Buildbox Forum, and Buildbox Discord. Follow these accounts below! We will be sending out email updates to everyone who signed up at buildbox.com/gamejam.

Have a complaint?

Please fill out this complaint form and we will get back to you as soon as possible.
