This is a 48 hour game making marathon, but spread out around two week-ends so you can choose the best moment to jam. It is focused on bad design, horrible mechanics, and stupid ideas. It runs from February 6th, at 8PM UTC, to February 15th, at midnight. This jam is a parody of the GMTK game jam, which you can learn about here.

Here is what you need to know:

Who can enter? Anyone, of any age, from anywhere. You can work alone or in teams to make the worst possible game.

What is the theme?  will be revealed this friday: 

What can I make my game in? Anything, provided you can upload a file that runs on Windows or browsers.

What assets can I use? Absolutely anything, whether you have the right to them or not. Feel free to reuse art or music from the public domain or even from existing games, I don't care. Just make sure you remain somewhat safe for work, as i'll have to make a video showcasing all the games. Although code-wise, I would prefer if you coded everything during the jam time.  However, please refrain from using AI generated content. I'm explicitly allowing everyone to steal whatever assets they need on purpose, no need to hide behind thousands of literal plagiarism machines. I want purposely bad games made by humans.

Who will judge the games? Games can be judged by anyone. I will also coax one of my friends into playing all the games and making a compilation video.

What will the games be judged on? This is a bad design contest, and anything goes. As a general rule rate more stars on criteria which fail excellently. For instance in the "Ear destruction" category, Final fantasy music would get a 1/5. A game that destroys your eardrums gets a 5/5. Here are the rating criteria:

  • Frustration (does your game force you to wait or redo a lot of content?)
  • Unfairness (how little does the player's skill impact gameplay?)
  • Confusion (how badly do you teach your mechanics?)
  • Uncanny valley (how ugly does your game look?)
  • Ear destruction (how bad is the audio?)
  • Bugs (or features in this case)
  • Microtransactions (or any BS triple AAA game practice. Please don't use actual money for this though)

Is there a Discord I can join? Yes! Click here to join it

Further rules:

  • You may participate in two jams at once if they happen at the same time and your game is bad enough to join my jam.
  • Games submitted to the GBTK Jam should not get the player banned from youtube/twitch so please remain somewhat SFW.
  • No VR. (or at least make sure the game can be played with a mouse and keyboard)
  • No genAI. I really don't want to see this ever.
  • Your game must run on its own and not require me to install other software/viruses
  • You may not enter a game that was made for a previous GBTK jam, but feel free to make sequels!
