The Dungeon23 Challenge is a Glorious D&D Delight

12 levels. 365 rooms. Behold the glory that is the Dungeon23 Challenge.

Over the past few weeks the hashtag #Dungeon23 has been trending on social media and has quickly been picked up by fans of D&D and tabletop roleplaying games. But what exactly is it? In this article we break down everything you need to know and how you can get involved.

What is the Dungeon23 Challenge?

Dungeon23 is an ongoing social media event in which participants will try to build a single mega dungeon over the course of a year. Each day, participants will design a new room and each month will consist of a single level. The goal is have a complete dungeon that consists of 12 levels and 365 rooms filled with traps, treasures, monsters and more, with participants encouraged to share their work in progress over the course of 2023.

The idea for Dungeon23 began in early December 2022 when RPG designer Sean McCoy (co-founder of Tuesday Knight Games and publisher of the award-winning tabletop RPG Mothership) tweeted about a new year-long dungeon project he was working on and included a photo of his notebook.

The idea quickly took on a life of its own and the #Dungeon23 hashtag was picked up by other D&D and TTRPG fans, with McCoy helping to provide a little bit more structure to the challenge via a post on Substack. Unlike other events, such as National Novel Writing Month (NaNoWriMo), there is currently no formal organization overseeing the Dungeon23 challenge, with the concept essentially taking a life of its own and being run and organized by fans.

How can you participate in the Dungeon23 Challenge?

Dungeon23 is open to anyone with an interest in the project. As McCoy and other champions of the challenge have pointed out, however, the main goal isn’t just to make a mega dungeon over the course of a year, it’s to try to challenge yourself to be creative, build a space for new ideas and create connections with the D&D and TTRPG community.

Online fans who are supporting the challenge have also pointed out that it doesn’t even have to be a traditional dungeon, and some participants are creating cities, mansions, post-apocalyptic ruins and even massive starship fleets. Additionally, a number of fans are adding in weekly “theme” challenges to add an extra level of creativity to their designs.

The idea, however, is to keep it simple, drawing a single room with a connecting hallway and sketching in a sentence or two of detail on any traps, monsters, magic items or secrets. Participants can create their dungeon masterpieces however they see fit, with many choosing to draw by hand and others designing using software or specialized tools.

McCoy offers a number tips on his Dungeon23 substack for participants who might be stuck or need a little inspiration. He also points out that it’s okay to miss a few days here and there. Again, the process itself is more important than the final result.
