Welcome to the first annual OPR Game Jam!

This is a 48hr game making marathon, focused on creating one-page miniatures games. The jam runs from May 8th, at 8PM UK time, to May 10th, at 8PM UK time. This is the first one-page game jam dedicated to miniature games ever, so let's make it great!

Submission Rules:

  1. The game has to follow the theme: Asymmetric Design
  2. The game must fit on a single sheet, using the template provided here:

    • The back page may optionally contain rules on unit creation or special rules.
  3. Every game must be submitted along with the following:

Please make sure to submit your game in .pdf format so that it's easy for everyone to read it on mobile and desktop!

Example of a what a correct submission should look like:

Here's everything else you need to know:

  • Who can submit? Anyone can submit a game,  and you may work alone or in teams.
  • Who will judge the games? The games will be judged by the public, and then the creator of OPR will highlight a few of his favourites on the OPR website. There is no winner or prize, it's all just for fun!
  • What will the games be judged on? This is a contest in simple, clear and interesting design, so gameplay and readability are more important than complexity and simulation. The criteria for judging will be "Design", "Originality" and "Adherence to the Theme".
  • Who has the rights on games created during the jam? The game creators retain the rights to their own games, and they won't become part of OPR's catalog of games unless specifically agreed between the creators and OPR after the jam.
  • Anything else? Submissions may not contain nudity, hateful language, or hateful images.
