GMTK Game Jam 2022 is over!

Thanks so much to everyone who made a game for GMTK Game Jam 2022. I have picked my favourites, and you can see them in the video below. You can also check out the public rankings, here.


The GMTK Game Jam is an annual game making marathon, where individuals and teams try to make a game that fits a theme, in just 48 hours.

Thousands of games are submitted as designers improve their skills, flex their creative muscles, and try to get their game featured on Game Maker’s Toolkit. You can see (and play!) the past winners here

This Year's Theme

The theme is "Roll of the Dice". That theme might immediately spark ideas of randomness and probability, or board games and casinos, but as always - you can interpret this theme however you like.

Key Information

Who can enter? Anyone, of any age, from anywhere. You can work alone or in teams.

When does the jam begin? The jam begins on the following day/time, depending on your time zone (see the countdown above if your time zone is not listed):

What is the theme? The theme is Roll of the Dice

What can I make my game in? Anything, provided you can upload a file that runs on Windows or browsers, and doesn't require any additional hardware or software.

What assets can I use? The game should be developed during the jam, but you may use pre-existing code and can use whatever art and audio assets you have the legal right to use.

When should I submit my game? While the jam concludes at 18:00 BST, there will be an additional two hours on the clock (until 20:00 BST) that is just for submitting your game. That being said, we recommend uploading something nice and early, and updating as you go! Once this concludes, all submissions will be shut - with no opportunities for late submissions!

Who will judge the games? Games will be judged by the public. Mark will then play the Top 100 games and pick his favourite 20. All of the results will be revealed when this process is over.

What will the games be judged on? Games will be ranked against the following criteria: enjoyment, creativity, and presentation.

Further Details

Main rules

Who can enter?

This is an online game jam, so anyone, from anywhere, aged 13 or older can enter the jam. (Those younger can take part, as long as a parent or guardian uploads the game).

You can work alone or in teams. There is no limit on the number of people per team and people can be in multiple teams.

Only one person needs to join and submit the game. However, if others on the team also join, they can be tagged as contributors. (On your game's itch page, pick "Edit", "More", "Admins", and follow the instructions). 

What's the theme?

The theme will be announced at the very beginning of the jam.

Your game should follow the theme, and you will be asked how your game fits the theme on the submission page. That being said, you will not be disqualified from the jam if your game doesn't adequately fit the theme. 

When does the jam begin and end?

Game Jam 2022 begins on July 15th at 18:00 BST. The jam ends on July 17th at 18:00 BST. There will be an additional two hours (taking us to 20:00 BST) for submitting the game, though you can submit at any time during the jam (and we recommend you get your game up early!)

What you can make

When it comes to what kind of game you can make, we’re ultimately looking for games that are suitable for a general audience, and that are really easy for people to download, play, and judge. With that in mind...

What can I make my game in?

You must produce a digital computer game, that runs on Windows - or web browsers supported by Windows. You can support additional platforms (such as Mac or mobile) if you like, but a Windows / browser build is necessary. 

The game file needs to be uploaded to when you submit.

You can make your game in whatever engine, programming language, or software you like. We recommend engines such as Unity, Unreal Engine, Game Maker, Godot, Construct, and PICO-8. 

You may use engines designed for specific genres such as RPG Maker or Adventure Game Studio, but we don't recommend it as the GMTK Jam is intended towards making games with brand new concepts and gameplay mechanics.

  • You can not make games for consoles (so no Super Mario Maker 2 levels or Dreams (PS4) creations).
  • You can not require the user to download additional software from external sources (so no ROMs for emulators, or games for Roblox. If your game requires additional files (like DLLs) they should be included in the download and not require separate installation). 
  • You can not require the user print things out (so no board or card games).
  • You can not require the user to have hardware beyond a keyboard and mouse (so no VR games, webcam games, and no controller-only games). 
  • The file limit is 1GB. You can compress your game as a ZIP, RAR, or 7Zip file (ZIP is preferred).

Can I make..?

We try not to put limitations on what people can make, as long as it fits the eligibility discussed above. So if you want to make a mediative walking simulator, a strange piece of interactive fiction, or a highly personal exploration of your own subconscious… go for it. 

Just note that many players will be alone (so they may not be able to adequately judge local multiplayer games) and will only have a few minutes to try your game (so get to the point quickly!)

Your game must not contain nudity, or hateful language or visuals. This could see your game being disqualified. Please consider avoiding extremely strong language and excessive gore, as the jam should be suitable for a general audience. If you’re uncertain, err on the side of being less gratuitous. 

As always, Mark and the mods can't decide, on a case by case basis, what is and isn't acceptable so please use your best judgement!

Please don’t make games about or based on Mark Brown, the GMTK brand, or any Jam mods - it’s easy for parody and inside jokes to go wrong. 

What you can use

This game jam is about making a game during a 48 hour period. This is a race to make a game, and everyone starts running when the jam begins! As such, we expect you to make the vast majority of the game during this time. 

However, as the jam is primarily about flexing your design chops, we don’t expect you to make everything in the time slot (unless you really want to!) So...

Can I use pre-existing code?

Yes! You can use pre-existing code, libraries, and functions. But we ask that you don’t write code specifically for this jam, ahead of time. 

You can also create things like a blank Unity project, a Github page, or your profile in advance to save time.

The jam moderators cannot advise you individually on what pre-existing code is or isn't allowed. So please use your best judgement and work within the spirit of the rules.

Can I use pre-existing art and / or audio?

Yes! You can use whatever art and audio you have the legal right to use. We'd recommend making your own stuff (especially your own art) but it's up to you.

That means you can use pre-existing sprites, textures, fonts, models, shaders, animations, sound effects, and music - including public domain assets, assets you have purchased, assets you have made yourself, or assets that are (legally-acceptable) derivative works of existing media. 

You should credit all external art and audio in your game description. 

Upon submission, you will be asked whether your team created the vast majority of the game's art during the jam. (This does include animations, but not shaders or fonts). And you will be asked if you made the vast majority of the game's music, during the 48 hour period. (This doesn't include sound effects).

This is a way of highlighting the artists and composers who were involved with the jam, and this will not impact your rating.

The jam moderators cannot advise you individually on what assets you can use, so if in doubt, be cautious and make your own stuff! And they cannot advise individually on what answer you should provide to the submission questions, so please use your best judgement.

Submitting a game

How do I submit a game?

You should upload your game to like it was any other game. From there you can upload the files, and provide additional details. 

You should make the game free (or let the person pick “any amount”), and you must set the game as "released", not "draft".

If you're submitting a Unity game and want to provide a version that works in browsers, you should set compression type to Gzip from Unity's WebGL Player Settings.

Then, you should come back to this page on, click submit game, and choose your game from the dropdown box. Answer the required questions to complete the submission!

To ensure that your game is in the jam, please go to your game's page and look for the badge that says "Submission to the GMTK Game Jam 2022" in the top right.

If it's there, you're in! If not, please submit again. If problems persist, please visit the Discord channel for technical assistance.

When should I submit the game?

You can submit the game at any point during the 48 hours, and we recommend that you get something up nice and early! However, there's an additional two hours at the end (from 18:00 to 20:00 BST) dedicated to submitting your game. 

Until submissions end at 20:00 BST, you can change the game as much as you want (such as uploading a new build, or uploading a separate Mac version, or changing the details) and it will automatically change the game that's in the jam. You don't need to un-submit and re-submit.

Help! I missed the deadline!

The jam ends at 18:00 BST. There are two additional hours for submitting your game to the website, ending at 20:00 BST. At this time, submissions will be closed - with no opportunity to upload or change your game. 

At 20:00 BST on July 17th 2022, uploads will be locked for the duration of the voting period. The GMTK Game Jam team cannot help you get your game uploaded or changed during this time.

During the voting period, you will not be able to change the game, and must not link to other versions in the description or comments. Whatever's uploaded to itch is what will be played and judged.

If we experience any issues with's servers due to the load, we may extend the deadline. More details will be on the GMTK Discord.

During the voting period

Can I change my game after the jam ends?

When the jam ends, there's a one week rating period (details below) where you must not change your game. Uploads to the jam will be locked, meaning you can no longer provide bug fixes, additional versions, or extra levels. 

Also, please do not put links to other builds (such as "Game jam upload has a bug! Please play this one!”) in your description or comments. This may see you being disqualified from the jam. Whatever you upload before the jam closes is what people will play and judge.

If you delete your game during this period, we will not be able to help you and you will be disqualified from the jam.

You can change your game's page during this time though, including the thumbnail, description text, screenshots, and page design. You'll want to do this as fast as possible though, as the majority of the ratings happen at the very start of the rating period.

Once the rating period is over, you're free to update your game however you please, charge for it, release it on other platforms - the game is yours, do what you wish with it! 

Are the games judged?

Yes! For one week after the jam ends, people will be able to rate your game against three criteria:

Enjoyment - How enjoyable the game is to play

Creativity - How interesting, original, creative, and inventive the underlying idea is

Presentation - How the game looks and sounds

These three criteria will add to to your Overall rating for your game. 

Everyone is eligible to rate games - and will be able to find them on the page for the jam, after it ends.

Those who submitted or contributed to a game will be able to judge whichever games they like. Others will have to vote on games provided at random, until they unlock full rating privileges.

At the end of the rating period, the overall rank for the games will not be immediately shown. Instead, the jam host Mark Brown will get to see the games and will play the top 100 ranked games in the overall category. He will then pick his favourite 20, and make a video.

When the video is released, the 20 winning games will be shown and the public rankings will also be displayed.

How does's ranking algorithm work? takes into account the number of ratings a game receives to ensure that things remain fair (for example, a game that receives 1 five-star ranking will not beat out a game that receives 100 four- and five-star rankings). The exact nature of this algorithm is not made public knowledge. 

Hey, this person is cheating!

I need art and audio!

Here are some places where you can find art, fonts, music, and sound effects for your games.

Many of the assets are eligible for use in the jam but check the license before using and provide credit in your game’s description!
