This jam is now over. It ran from 2021-12-06 00:00:00 to 2021-12-12 23:59:59. View 17 entries

This year the One-Page RPG Jam was the biggest TTRPG jam in’s history. We’re going to close out the year with a look back at the previous jams, with a week-long hackathon.


Pick an entry from either of the two previous one-page RPG jams, and hack it into something new. You could take a main mechanic and build on it, take a game and change the genre, mash-up two different games, or anything else that inspires you.

The new game doesn’t have to be a single page, but with only a week for this jam it’s encouraged to keep the project small in scope; especially as the game you’re hacking will be one page already.

Previous Jams
