General Game Jam FAQs

  1. What is a game jam? A game jam is a creative exercise that lets you practice making a game from start to finish in a defined, limited amount of time. Adriel Wallick, the founder of Train Jam, has described game jams as “practicing the skill of finishing.” It’s easy to come up with countless game ideas, but actually picking one and making it a reality is a worthy challenge!

    For beginner jammers, you’ll typically have the most fun doing a game jam if your primary goal is to learn something new, whether or not you finish and submit a game.

  2. Can I make a video game if I'm not great at coding? Or know how to do art? etc. Absolutely! As far as game design lessons go: check out our playlist on how to make your first game which includes tips that are very relevant for game jams.

    Extra Credits gets a lot of questions about which development program to get started with and the truth is, it doesn't really matter since different software is better suited to different types of genres. If you have a specific type of game in mind that you want to make (e.g. a 2D platformer) but don't know where to start, you should check out this interactive quiz which will help you find some good software to start learning.

    Unless the jam instructions/theme specifies otherwise, remember that you are also free to make and submit a “real world” game (e.g. a board game, a tabletop game, a social game, etc.) where your primary materials are pen and paper rather than lines of code and pixels. This is a great way to practice game design directly without having to fuss too much about aesthetics and technical know-how. Just remember to make it a playable game still, not just a design document!

  3. Should I have a team? You can, if you want to. For remotely distributed teams, we recommend 2-3 people to a team, because it can be hard to coordinate/distribute work evenly with a bigger team when multiple time zones might be involved. If you're working with friends locally, 4-5 people is a safe maximum. Remember, learning how to communicate and cooperate with others is its own extremely important game development skill! It’s not good manners to boss around other people, or act so isolated that your team doesn’t know what you’re working on.

  4. Can I contribute to multiple games in a jam instead of just one game/team? Yes, you definitely can! Some people and some skills, like music & audio production, are extremely well suited for this type of collaboration.

  5. How can I meet other jammers? We have a Discord community for the benefit of any jammers who want to find collaborators, share their progress, and ask for feedback. This Discord community is linked to on the game jam pages themselves.

  6. Can I use assets I’ve already made before the jam starts? Yes, BUT!!! The point is to see what you can make and finish within the jam’s designated time period. Plus, you don’t even know what the theme is—allow the jam theme to inspire what you’re going to make, instead of retroactively squishing in a pre-created game or assets to make it “count” as the theme. That said, if these “assets” in question are something that is very theme-neutral, such as your own custom engine, scripts, etc. that is all fine to use. This also applies if you want to decide in advance that you will use a particular game dev tool of your choice (unless the jam rules say otherwise). This should all count as “preparation” work, not as a cheat code to give yourself extra content development time.

  7. Can I use other people’s work in my game? Yes, but only if:

    —You obtained it legally (e.g. you downloaded free assets from the Unity store, you bought a font from a graphic design website, etc.).

    —The author/creator has given you their permission, in writing, to use their work in your game.

    —The work (such as music, art, etc.) has a Creative Commons license attached to it, or is known to be in the public domain. If you’re not sure what these terms mean, spend a little time reading about copyright in advance, so you know how to identify and use this work. There are many, many websites and search tools for finding free (and 100% legal) art, music, and so forth. They are great to use in a pinch if you don’t have the time or desire to create your own assets.

    In any case, it’s always a good idea to source and credit where the content in your game came from, if you didn’t create it entirely yourself!

  8. Can my game have mature, dark, or otherwise not necessarily “family-friendly” themes in it? Yes, absolutely, but please do take care to warn and prepare players in advance. A content warning (sometimes abbreviated CW, or TW for trigger warning) is a brief written description, probably 1-2 sentences, that is visible on the game description webpage and/or in the game itself. Example: “content warning: rapidly flashing lights that can trigger photosensitivity; mention of racist slurs; explicit descriptions of domestic violence.”

    We also encourage jammers to avoid making controversial content purely for the “shock value”, e.g. for the sole purpose of upsetting or disgusting the player. Don’t be an edgelord.

  9. I didn’t finish my game on time; can I still enter it into the jam? There are a few different answers depending on your situation. However, you should always feel free to continue working on your game and publishing it on itch.io (or elsewhere) when you’re ready. Game jams are great ways to get started on bigger projects! You can still be proud of what you’ve made so far.

    Ultimately, what guides our decision-making is based on trying to have everyone be on the same playing field (or should we say, jamming field). Everyone starts off with the same theme, and the exact same amount of time to make a game—it is up to each jammer, and/or each team, to decide how to interpret the theme and how to use their time. We will have a limited number of one-use “late submit” links available only for emergencies, at the sole discretion of the jam coordinator.

    Now, on to the hypothetical scenarios:

    • Situation A: You didn’t finish your game on time because you didn’t manage your time well. Maybe your design scope was too big for what you could reasonably accomplish. (For example, maybe you went to a movie and dinner on Saturday night (4+ hours), but still insisted on keeping a feature that takes 4+ hours to design and build.) This situation is extremely common in game dev, even for experienced designers. Time management is a skill that doesn’t come naturally to most of us—we just keep practicing at it. We cannot help you in this situation. Learn from your experience, and decide if you’d like to keep working on your game anyway for its own sake.

    • Situation B: The game is finished, but you had problems uploading to itch.io before the submission period closed. First off—please please please, remember that playtesting and exporting is a valuable part of your game jam experience, and you should absolutely schedule in ample time to do that. Waiting until the last 15 minutes to create your itch.io account and start uploading is a very bad idea. (Not to mention, we ask you some questions you have to fill out when you’re submitting your game!)

      However, we know that emergencies can and do happen even to the most well-prepared folks. If this is you, please send a message to one of the game jam Discord moderators, describing exactly what happened/how you’re planning to address it. If you are not on Discord, you may send an email to our contact inbox, but please don’t contact us in both places at once.

    • Situation C: Your game is finished, and you did upload it, but after the deadline passed you just now realized there’s a bug that needs to be fixed (minor or major), and you want to fix it. We have previously tried a relaxed policy with letting folks edit their games after the submission deadline passed, but found that a lot of jammers weren’t abiding by our request to contact us first before making those edits, which ultimately compromises the purpose of a limited-time jam since we didn’t know what kind of edits were being made and why.

      We believe that ultimately our current policy—locking submissions from further edits for a few weeks afterwards—will encourage more jammers to stop working on their games early enough that they can do proper playtesting and debugging well before the deadline.

      We encourage you to make a separate build of your game if you want to keep working on and expanding it, so that it is clearly differentiated from the game jam version.

    • Situation D: You waited too long to contact us about your issue. The best time to let us know about a problem is as soon as you become aware of it, or even before the problem happens (e.g. if you anticipate an unusual circumstance outside of your control that will interfere with your ability to submit on time). We will start playing/assessing the games very shortly after the jam ends, so don’t purposely wait to send us a message—it’ll be too late.

      Please read Situation B for info on how to contact us.

  10. Why was a game removed from the jam? This is an extremely rare occurrence (less than 2% of all games submitted) that happens for one of these reasons. If you believe your game was removed by mistake, please contact us.

    • Someone submitted a game that was clearly made before the jam even started. The publication date on the game page tells us this immediately. There’s probably a term for this behavior already, but if not, we’ll just call it “spam-jamming.” It’s not good etiquette to submit a game you already made to a jam that you’re not actually participating in, because you’re looking for some pageviews and downloads. Usually these games also look unusually polished and have a much larger design scope than something you’d see made in a weekend.

    • There is literally no game attached to the entry. Maybe you started an entry, submitted it, but forgot to keep working on it and upload the finished game file? Sadness :( Don’t forget to actually attach your playable entry!

    • The game doesn’t fit our community standards.

  11. On itch.io I noticed that I can sell my game; is that ok? To make it easiest for us (and your fellow jammers) to play your game, we politely request that you make the game “free,” or to only enable the optional “tip jar” that players will see and can interact with when they download the game. In our experience, jam games are usually enhanced/upgraded with more content and features after the jam ends, before they are put behind a mandatory paywall.

    Please be extra-familiar with copyright rules, if you are using non-original assets in your game and you are planning to sell it.

FAQ regarding the game jam episodes of “Games You Might Not Have Tried”

The reason why we at Extra Credits attempt to play/assess everyone’s game jam entry is because we want to make an episode that features our favorite, most thought-provoking and creative entries. This episode usually goes up within 2 months of the jam’s conclusion.

If your game is selected to be included in one of these episodes, you will receive an email from us within 1 month of the jam’s conclusion, with additional information on what happens next.

  1. If I submit a game in [X format], can you play it? Unless the jam rules specify otherwise (always defer to them first, as some future jams may be themed to encourage different development tools), in general we can always play games that are:

    • Compatible with Windows 10

    • Compatible with web browsers

    • Use other file formats that are widely accepted and accessible (e.g. PDFs for tabletop games)

    We usually have difficulty playing games that are only exported in the following formats:

    • Android

    We generally cannot play games that are only exported in the following formats:

    • iOS

    • Mac-only

    • Linux-only

    • Virtual reality

    • Any unique hardware requirements, such as requiring players to use a Raspberry Pi, a hacked console, an emulator, etc.

    If you really cannot export/upload your game in one of the preferred formats listed first, we strongly encourage you to attach a YouTube video demonstrating gameplay to your itch.io game page. In fact, that’s generally always a smart thing to do (if you have time), in case there are ever any issues with us being able to run your game. (Also, sometimes jammers like to make very technically challenging games, which is fine to do, but if that’s the case for your game we like being able to watch a complete let’s-play of it so that we can appreciate the ending even if we aren’t able to get there ourselves due to our own limited time.)

    An important side note: always make it easy for people to check out your game by including clear gameplay instructions (preferably in-game), and making the installation process as simplistic and no-fuss as possible. Not everyone who plays your game is as tech-savvy as you might be.

  2. What criteria do you use for deciding which games get selected for a GYMNHT episode? Keeping in mind the natural limitations of a game jam and the wide diversity of skills and personalities represented in a jam, we generally try to apply the same criteria we use for all our other GYMNHT episodes, which you can read about on this page! The short answer is “does this game do something interesting, and does it feel reasonably polished?”

    It is also worth mentioning that we honestly feel that very many games submitted to the jams have fulfilled this criteria in some way, but due to the time limitations of the episode itself, only a handful of games are mentioned in each video.

    Our best advice for accomplishing this is to (1) have fun with this—no really, a game jam is supposed to be fun, and if anything you should be competing with yourself and not against other jammers, (2) play to your own strengths, and (3) seriously, don’t over-scope the design!

    Want to use public domain clip art instead of your own “programmer art” scribbles? Go for it! Do you excel at writing? Really focus in on that—but don’t accidentally set yourself up to write a novel, when what you really want to aim for is a minute of gameplay that embodies a particular setting or emotion.

    Let’s also define that complicated word “polish” in practical terms for Extra Credits jams. We believe the “polish” of a game is not represented by just one element, but by the entire composition of the game. Audio design, dialogue, menu interface, gameplay controls, etc. can all play an important role in establishing “polish”—aka, the sense you get, as a player, that every element has been consciously chosen and deliberately designed. Any glitches/bugs that may exist don’t significantly detract from the experience. A game might feature very impressive graphics, but not feel particularly interesting or satisfying gameplay-wise. To the best of our ability (we are human, after all), we try to examine each game holistically.
