Highlights (New Additions)

Second Guess Jam - Second Guess games like One White Eye or The Date explore a wide variety of of topics from horror to romance and potentially anything in between. The central conceits are that it's a one page solo game, utilizing a d20 based journaling system, and twist character perceptions as they go, which you can read more about in the excerpt below and in the SRD itself.

Creative Commons Jam - Welcome to the Creative Commons jam! This is a game jam where people can submit tabletop and video games, images, sounds, and other assets they have created that have a Creative Commons license. The Creative Commons license comes in many types and allows people to share their work so others can create new things. This jam hopes to inspire game developers to release their materials under a Creative Commons license and give others resources for game development.

YoJambo - One challenge we've noticed in our quest to introduce D&D players to new systems is that many newcomers to indie TTRPGs rely on pre-written adventure materials. The goal in creating YoJambo is to help introduce new players to indie games by creating scenarios using Kurosawa's classic film "Yojimbo" as inspiration.

Generator Jam 2021 - The rules are simple: Create a random generator that can be used in a tabletop RPG. The generator can be for anything: magic spells, characters, locations, maps, weather, names, creatures, monsters, weapons, etc. The method of generation can be anything: dice, cards, books, numbers, letters, a calendar, etc. Your generator can be small and simple, or long and complex. It can be designed for a specific rule system, or compatible with any system. You can submit as many times as you would like.

Story Synth Summer Jam - Welcome to the Story Synth Summer Jam! This is a low-key game jam lasting from June through August to create games using Story Synth.

MMnMM-Bop! - Welcome, everybody, to the magnificent, miraculous, majestic, mind-blowing MMnMM-Bop! This is a game jam bop for Marvelous Mutations & Merry Musicians!, a game where you play as traveling mutant musicians going on adventures in a weird, fantastical, post-post-apocalyptic world!

Indiepocalypse Issue #18 (Paying Anthology) - Simply, it's a monthly collection of games from 10 developers all wrapped up in one package. That the developers get paid for! Up front and on the back end! There will also be a short digital zine with a page for each game. Creators are free to design their page to their own liking or submit text and pictures to be laid out for them.

Solarpunk Jam - be SOLAR. Use sustainable technologies and energy production to make Earth a greener place to live in. be PUNK. Imagine a world that challenges the systems we live in. Strive for this better future.

Space Western Summer Jam - Space Western Summer Jam is the second in a series of seasonal TTRPG physical game jams I'm running! This one has a theme of Space Westerns, and lasts for all of Summer!

Galactic 2E Jam! - Welcome to the Galactic 2E jam! This is a jam for making supplemental material for the game Galactic 2E. That can mean whatever you want: expansion playbooks, pillars, places, and/or traits, story prompts, something cooler i haven't even thought about... hell if you wanna make a totally different game using its modified BoB system, I'm certainly not going to stop you.

Applied Hope: The Solarpunk & Utopias Jam - Applied Hope is a jam about solarpunk and/or utopian thinking and practice. Define ‘solarpunk’ and/or ‘utopia’ any way you like. Your goal is to create a game or anything you like. Have fun. Be weird. There will be some prizes for TTRPG entries.

Gamer Games Game Jam - The purpose is to show off our true gamer cred by designing TTRPGs and TTRPG materials based on our favorite video games!

Camp NaNo Jam - Start, complete, or just work on an analogue/physical game or game supplement during April 2021's Camp NaNoWriMo. The jam is open through the first week of May, and another one will be hosted for July's Camp! Not officially associated with NaNoWriMo.org.

Jam Without Numbers - The black screen when switching channels on a TV is equally as important as the actual show is. The background noise of your computer fans whirring let you know that it's alive. The small things you don't think about hold up the actual content of what you're doing.bThis jam is dedicated to the parts of games that aren't games. I want this to be permission to Just Write and not have to make it gameable. Make whatever you want, BUT it can't be a mechanic, a random table, a stat block... Nothing that's part of a game.

MÖRK BORG Album Crawl: Jam Session 2: ALBUM CRAWL ROCKS THE 80s - Today, members of the Trve Mörk Borg Discord Server unleash Album Crawl: Jam Session 2: ALBUM CRAWL ROCKS THE 80s. In this jam, everyone is invited to created adventures, dungeons, and other dread inspirations for the roleplaying game MÖRK BORG. However, your glorious content MUST BE THEMED after an album from the '80s. Not '80s inspired, not '90s. 1980 to 1989, baby.

Spring From the Graves Jam - The Spring From the Graves Jam is the first in a series of seasonal jams I'm planning to run! This one has a theme of Necromancy, and lasts for all of Spring!

LUMEN Jam - This jam is for making anything you want with the newly released LUMEN system. That could mean making a brand new game, or creating some new classes, rules, or supplements for existing LUMEN RPGs! Check out each other's submissions as they come in, you might find something you want to build with.

JAM THIS ALBUM! ♫ - This jam gives you the opportunity to celebrate music. Take inspiration from an album that is dear to your heart (or an imaginary album using all the typical features of the genre of your choice). You are free to choose any band or artist, in any genre: Rock, Metal, Grunge, Folk, Pop, Electro, Jazz, Classical music… Anything you want!

The Five Powers Jam #2 - New Year - New Jam! This Jam follows the same idea as the first Five Powers Jam, but this time we will take more time! Good things need time - but that doesn't mean, you can't submit something you created in a rush of inspiration! In fact, being creative is the main reason to have a Game Jam to begin with, so don't overthink this! Have fun with it!

DOS Games Spring Jam 2021 - This is a casual jam for creating games that would fit in with the games released for the DOS operating system during the 80s and 90s. DOS-inspired utilities, zines about DOS games, and tabletop games inspired by games from that era are welcome too! This jam hopes to be a good opportunity to start creating games if you've never made one before. There's no voting in this game jam so feel free to experiment and try new things.

Megadungeon Jam - Hello! Welcome to the Megadungeon Jam! This was born out of a bit of a confession on twitter at one of my deeper design goals. I've always wanted to make a megadungeon but had never even attempted to endeavour at how to do so. It seemed many others felt the same, so here's a year-long opportunity to try your hand!

Domino Jam - This jam is all about creating games that utilize dominos in new and interesting ways. We could use dominos to create whole new worlds, fantastical maps, or epic timelines. Perhaps the dominos could create patterns that take the shape of a fearsome enemy. Maybe the dominos are used as clout during a heated argument, with the winner slamming their tile down in victory.
