Written a one-page game and open to folks writing an adventure for it? Share a link and a short summary in this thread.
For example:
Wild Places is a GM-led, rules-light system designed for single-session play. Characters are normal people who find themselves in strange situations. Inspired by authors like Susan Cooper, Marcus Sedgwick, and Suzanna Clarke, it is not designed for combat.
FUEGO: Ignition Edition is a highly streamlined system for fast-paced adventures in any setting. It uses an original dice mechanic and is designed to be hacked: you can easily reskin the game elements to fit your favorite genre. Available in English and Spanish.
Starbound Ventures is a fast, rules-light TTRPG designed with heroic pulp sci-fi one-shot adventures in mind, but can be used with any action-heavy setting. Players can quickly level up, turn failures into future advantages, and resolve challenges without the GM needing to calculate target numbers. The game also includes a quick enemy-creation tool. Feel free to use, modify, or expand upon the system however you see fit to better suit your adventure!
For those interested in a cozy, journaling vibe Wash Day is a GMless, narrative TTRPG for 1 or 2 players. Record your interactions and conversations with your clients solo, or play out the scenarios with a partner. Players can repeat for as many clients or appointments as you’d like. I don't know if I have time to create a one-off adventure but I think it would be cool to see some narrative episodes take off with the story. Some immediate ideas that are free to use: the hairstylist trying to build her own salon, a one-shot exploring one of the fractured pasts in the original game, the hairstylist suddenly becoming involved in a mystery when her regular client goes missing.
Would you like to be a dirtbag in kinda-the-90s Tampa? This is the one-page game for you, so come on and write your best "Florida Man" scenario for 199X I Shot A Man in Tampa. There's also some "exclusion zone" elements in addition to regular weird 199X Florida as The Fracture has opened up and made Tampa even weirder. Fast character creation and task resolution accompany this 24XX-based one-page game. Enjoy!
For the 2026 One-Page RPG JAM - I made a TTRPG kit/system that is based upon my favorite hacks for PBtA, RISUS, Goblin City, and a few other amazing RPGs. No Stats. No Hit Points. No Death. Just Complications, Conditions, and a very chaotic DICE RESOLUTION system. It currently doesn’t have archetypes or playbooks - but those should be pretty easy to add-on.
I’ve given it an easy license for personal or commercial use as a gift to our TTRPG hacker/designer community.
I’m going to try making a few settings/adventures for it. I hope you will too…
Halfling Heist is a rules-light game about a group of halflings trying to pull off a harmless but daring heist in their cozy village.
You must balance two stats: Halfling and Heist. Successful Heist actions pull you deeper into the job, while failure pushes you back toward your comfortable halfling ways. Go too far toward Halfling and you abandon the heist for teatime or a relaxing bath. Go too far toward Heist and you become convinced the others are cutting you out of the score and go solo. Your Connection to another halfling can bring you back into the job.
I’m planning to make an adventure for it myself, but I’d be happy if someone else does too! For this jam, you’re welcome to create and share a free adventure for Halfling Heist. Just credit H.C. Royalty as the creator of the game and link back to the game on itch.io. Please don’t reproduce the full rules or logo in your adventure. Thanks!
Grand Larceny is a PBTA-inspired high-tech heist system that uses Uno or Tarot cards as the "dice" randomizer. You have the typical types of characters (Face, Ghost, Nerd, Weight, Wheel) who need to plan and execute some sort of caper to steal or steal back a fortune. Touchstone inspiration from Leverage, Ocean's Eleven, Reservoir Dogs, etc.
No license required. It'd be nice if you shot me a reference, but as I have released it as CC-0, that's not necessary either.
Pocket Dagon is a skills only based game requiring polyhedral dice. Players portray castaways with amnesia on a deserted island that is lost in time.
Inspired by
“Dagon” (H P Lovecraft),
“The Most Dangerous Game” (Richard Connell),
The Bourne Identity (2002),
Lost --TV series (2004),
Kong: Skull Island (2017),
and of course, Gilligan’s Island (1964)
Flamboyance is half TTRPG and half LARP - fights are resolved by hand slapping games. It's a swashbuckling system ideally suited for over-the-top action in the vein of pirates, highwaymen, and merry bands of bandits. The perfect adventure is a heist! The system is a simple 2d6 roll: success and cost, modifying a handful of stats that influence overall status.
I encourage inventing more dueling styles! Please credit the game author and make your adventure either free or PWYW.

Similar in theme is my recent entry for the Appx N Jam (somebody stop me if those aren't what this jam is looking for) Rogues in the Manse, a system-neutral dungeon crawl set in a far future where player are retired Musketeers guarding the centuries-old relic of Dumas' characters. Swashbuckling focused on mouthing off, and misusing everyday items! Possibility for ultratech musketeering!
From Death Do Us Part is a GMless, rules-light storytelling RPG for two players. Horror romcom stuff. You play a married couple who died together and have been returned as zombies. You lose bits of your body but slowly regain memories of what happened in your life. Plays in a single sitting, needs only a couple of d6, only two major stats.
Inspired by all the weird undead dramedies you can imagine, like the film Death Becomes Her or the web animation Zombie Stage. CC BY 4.0 licence so you're welcome to make whatever with attribution.
Zombieees is a chaotic wacky supernatural game where you play as zombies, with a quick adventure generator table you can use as inspo to flesh out. Super simple mechanics and vibes, designed to be easy to pick up for new players and kids. I also wrote an adventure module for this where you play zombie elves in a classic Halloween/Christmas mash up too if you want further reading.
Cryptid Keeper and Prehistoric Keeper are cozy games where you take care of critters and shenanigans happen. These also come with events generators but it would be super cool if you wanted to write an adventure with the premise(s).
All three of these games are PWYW and you are free to use them for this jam if you wish to, just remember to credit with attribution and you're good!
Rot Barrow is a deadly one-page fantasy tabletop role-playing game for one or more players.
Create a party of four doomed adventurers and enter an endless barrow filled with foul beasts, hidden chambers, traps, and treasure. Murder. Pillage. Gloat.
Designed for both solo and group play, Rot Barrow features fast character creation, deadly combat, procedural dungeon generation, and simple oracles for playing without a referee.
There is no final room. The barrow continues as long as you dare to explore it.
All you need to play is one six-sided die, a pencil, and paper.
