Welcome to the 2026 isometric dungeon jam, the goal is to make a one page dungeon in 10 days. The dungeon can be in any system you like!
This year there will be a theme, following the theme is not mandatory but would be fun!
Non-Euclidean describes spaces that break the normal rules of geometry where angles, distances, and directions don’t behave as expected. A Non-Euclidean dungeon might loop back on itself in impossible ways, contain rooms larger inside than out, or feature shifting corridors that defy spatial logic. You are free to interpret this however you want: maybe the dungeon has two-dimensional sections or a mirrored version?
What is a one page dungeon?
A one page dungeon is a complete, self-contained adventure that fits entirely on a single page. It might include a map, room descriptions, encounters, and loot. The goal is to keep it concise, creative, and easy to pick up and play in any system.
What is isometric?
Isometric refers to a visual style that shows a three-dimensional space on a two-dimensional surface without using traditional perspective. In this style, the dungeon’s rooms and corridors are drawn at consistent angles (often 30° or 45°), giving a sense of depth and structure without requiring a 3D space.
Rules
- No AI generated content.
- Keep the dungeon on one page, putting the descriptions on another page is allowed but not in the spirit of this jam.
- Make it work on print, small text is not ideal.
- Only dungeons made during the jam period; you are allowed to finish old projects, but the majority of the work should be done during the jam period.
- Have fun! The jam is not ranked, this is your opportunity to try something wacky.
