Eureka: Investigative Urban Fantasy is a groundbreaking TTRPG that revolutionizes mystery investigation of all kinds! The rulebook is available at this link for free! This community event gives long-time fans and newcomers alike a chance to flex their mystery-writing muscles. 

Leave behind the days of "We walk into the room and roll Investigate." Eureka: Investigative Urban Fantasy is a TTRPG all about investigation, and its purpose-driven mechanics let players take initiative, use their characters' unique strengths to find clues, and deduce conclusions themselves. This game jam will bring the community together to write more mysteries for their characters to solve, put together in adventure module form.

 You can find a helpful guide to writing Eureka mystery modules in Chapter 7 of the Eureka: Investigative Urban Fantasy rulebook linked above.

This game jam is non-competitive, but the developers' favorites will be linked on the Eureka: Investigative Urban Fantasy store page so everyone can play through your creation! You can work alone or in a team, as long as you follow these basic rules.

Rules

Submissions Must Be Adventure Modules and Be Compatible with Eureka: This game jam is for mystery adventure modules to be run with Eureka: Investigative Urban Fantasy. If you're unfamiliar, an adventure module is a guide for game masters to running a specific scenario for their gaming group. You can find an example of one made for Eureka alongside the rulebook linked above.

Follow the Theme: The theme/prompt picked out by our patreon subscribers is "The Call." By design, this prompt is flexible and leaves room for interpretation - are the characters beset by mysterious phone calls? answering a mysterious call for help in the forest? or something far stranger? (Just remember not to make it about mind-control - Eureka doesn't have that.) Your submission can be about any sort of mystery, as long as it is obviously inspired by this prompt in some way, however you interpret it. Just also make sure to follow the rest of the rules below.

Third-person Verbiage: Avoid saying "you" when referring to player-characters.

Separation of Player and Character: Ensure that your module says "investigators" when it is referring to the player-characters, and "players" when it is referring to the real people sitting around the table, and don't get them mixed up.

Characters Can Be Bigoted, but We'd Rather You Weren't: NPCs in your module may express hateful attitudes, but we do not approve of hateful attitudes from submitters themselves. 

Stay Grounded in Eureka's Lore: Please keep your module roughly within the bounds of what the world of Eureka offers. You can read more about this within the first half of Chapter 8 in the rulebook linked above. (And remember, your submission doesn't have to be a paranormal mystery!)

Submissions Must be 5,000 Words Minimum: There is no upper limit, so be careful not to overdo it, as long as your submission has at least 5,000 words. This is the bare minimum size. Most good Eureka: Investigative Urban Fantasy adventure modules are about 50-100 pages, as Eureka really stresses providing detailed information to the GM and players alike.

No Generative AI: Do not submit anything that has been created in whole or in part through the use of generative "AI."

We Don't Own Your Submission: Your submission is still your property. You can even sell it after the game jam is concluded if you want. Though if you do, we recommend you keep working on it a bit to polish it up, since one month is plenty of time to get a first draft out, but even the best submissions will benefit from some critique and further refinement and editing!
