What is Mini Jam?

Mini jam is a 72-hour-long game development jam that occurs every two weeks on Itch.io.

The main focus of this jam is the mandatory limitation is announced as soon as the jam starts. The theme is provided early, so you can plan ahead. Just keep in mind that you may have to change your idea when the limitation is revealed.  This jam's theme is Underground. Said theme is purely inspirational and it's not required that you incorporate it into your game if you don't want to. Feel free to interpret it however you want.

If you are unable to submit your game before the deadline, do not panic. There will be an announcement on the discord as well as a post in the jam community tab explaining the steps necessary to submit your game late.

Join the discord server if you have any questions, want to be notified of any news, or just want to hang out with fellow jammers.

Limitation

The limitation is a special condition that your game must follow, but is entirely open to interpretation. If you are unsure if your idea does or doesn't fit the limitation,  just remember that everyone will interpret it differently. If you believe in your interpretation, chances are, someone else will too.

Limitation: Pocket sized

You may Interpret this limitation in any way you see fit

Ratings

At the end of the Jam, there will be a rating period that lasts 5 days. Anyone who submits a game to the jam, as well as any team members added as contributors to your game's project page can rate other games for the jam. Games will be rated on the following criteria:

  • Enjoyment - How much you enjoyed your time with the game.
  • Concept  - How interesting or unique the main focus of the game was.
  • Presentation  - How well executed the main focus of the game was.
  • Use of limitation - How well the game incorporated the given limitation.

Keep in mind that while the limitation is mandatory, the theme is purely for inspiration, and you should not rate a game differently based on how well the theme was incorporated. 

Rules

  • Read the rules

    Not reading the rules is not an excuse for breaking them.

  • Follow the limitation

    It is mandatory that you incorporate the jam's limitation into your game. This said, how you choose to interpret its meaning and go about incorporating it is entirely up to you.

  • The game must be made for the jam

    You cannot submit previously made games to the jam. This jam is about creating something new in the given period of time. Games made before the jam will be removed.

  • Keep game content clean

  • Answer submission questions honestly
