This is a fan-made jam for One-Page Dungeon Contest, to create a small hub for like-minded individuals and inspire, question and encourage each other. Let's make something beautiful!

Theme: Never Split the Party!

It has happened to every band of adventurers before: A fork in the forest road, two diverging treks in the cavern, a choice to join the king or the rebellion. Do you pick a path together, or do you separate, hoping to find double the spoils? Will you be rewarded for your ingenuity, or punished for your disunity?

For your one-page dungeon, your party will face important choices and decisions. Do you make the choice together, or choose multiple paths? Will independence and separation be rewarded, or will the warning of old once again be written on your tombstone?

  • Use of the theme is not required to enter the contest.

Contest Judging Guidelines

I am not a judge for this contest. These guidelines are only relevant if you want to submit your dungeons to the contest. For more information, read the official Judging Guidelines.

  • Creativity/Originality (C/O): Did you submit an original or creative idea? Does your OPD stand out from other submissions? Have you developed a theme or mood?
  • Art/Design (A/D): Is the art in your OPD appealing to look at? Is your layout intuitive and easy to follow? Have you avoided cluttering too much onto the page? 
  • Writing/Content (W/C): Do the words in your submission describe what your OPD is all about? Does your content also convey a story, mood, or theme? Have you avoided spelling and grammar mistakes? 
  • Playability/Functionality (P/F): Could a game master take your OPD and realistically run it? Would players be able to meaningfully interact with your OPD? Can multiple game systems support it? 
  • Personal Impression (P.I.): The most subjective of the categories, this score reflects a judge’s personal preference of your work as a whole.
