Here's everything else you need to know:

  • Who can submit? Anyone can submit a game,  and you may work alone or in teams.
  • How many games can be submitted? Each participant/team may only submit one game.
  • Who will judge the games? The games will be judged by the public, and then we will highlight the top 3 voted games 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 are "Concept & Originality", "Mechanics & Clarity" 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 catalogue 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.
