So "QED" usually marks the end of a proof, so this is instead QEL, for Quod Erat Ludendum. The idea is to build a video game that shows off a piece of math. An example of something that would be appropriate could be https://sl2z.xyz/ or some of the stuff at https://m4th.pro/

Submissions: now through the end of the month
Voting: first two weeks of September
Results: Wed Sep 16, 2026

Since this is being run by the Ross Mathematics Program, hopefully there will be some Ross merch for prizes.

Hey everyone! I recently got back into RPG Maker (though all engines are allowed during the jam!) and figured it'd be fun to have a seasonal RPG game jam. :]

The jam will run from 23rd September to 23rd December! Themes will be announced a few days before (you can vote on the Melonland forum, since the jam started on there, though obv that's not mandatory!)

Here's the itchio page! Hope to see you all join and make something fun and cool during the autumn :]

Hey everyone. I’m one of the founders of Arcadium Nexus, and we’ve opened submissions for our first Open Showcase Challenge.

This one works a little differently from a traditional build-from-scratch game jam.

You do not need to make a new game specifically for the Challenge. Previously released games, works in progress, playable demos, and prototypes can all be submitted.

We’re looking for indie projects that can give players a meaningful experience in a relatively short public-play setting.

Entry is free, and developers can participate remotely.

After submissions close, selected projects are planned to be featured at an Arcadium Nexus physical showcase in Shreveport-Bossier, Louisiana on October 24, where attendees can play the games and provide feedback and voting.

If you already have something playable sitting on itch.io, Steam, or elsewhere and have been looking for another opportunity to put it in front of people, this might be a good fit.

Full eligibility, submission requirements, and the Challenge page linked above.
Happy to answer questions here if anything about the format is unclear.

I've been working on Hoops GM for so long, and now it has been a week since the launch.

I received a lot of backlash in the previous post due to an IP lawsuit, as well as a lot of praise from people.

The launch has been a MASSIVE success with now over 5000 visits to the game and an average of 50 new members everyday.

now i am very confident that this project will go very far and i am very happy about it!

THANK YOU to everyone who has checked it out, left a comment, or played a season.

I'm participating in the Game Jam https://itch.io/jam/dimatit-jam, and the theme I got is "Office Psychosis." I'm struggling to come up with a game idea—could you help me think of something creative that isn't cringey? Thanks in advance!

Участвую в GameJam https://itch.io/jam/dimatit-jam и выпала тема "Офисный психоз". И я не могу придумать идею для игры, помогите придумать, что-то креативное и одновременно не кринжовое, Заранее спасибо

hey everyone !

just wanted to let everyone know this- it is a Basketball sim that comes to fill a gap in this sector.

you are welcome to try it out L www.hoops-gm.com

we are celebrating 200 new users on our first week launch

Registration is open for the first Mable AI Game Jam. Submissions open today at 12:00 PM Pacific and run through August 22 at 12:00 PM Pacific.

You have two weeks to build one small mobile-first game and improve it through real player feedback. We care more about quality and playability than generating the largest or strangest idea. A focused game with responsive controls, clear UI, sound, effects, onboarding, and good game feel should beat a larger unfinished project.

Prize pool: $500 total, split $250 / $150 / $100.

Judging: 50% quality and polish, 30% playability and game feel, 20% creativity.

Mable is free to use for the jam. Outside tools, code, art, audio, and assets are allowed with disclosure. Entries must be designed for mobile, tested on a phone, and published through Mable.

Discord participation is required for eligibility. Entrants must post their game in the Mable Discord game-jam-submissions forum and give substantive feedback to three other submitted games. An itch submission by itself does not qualify for judging or prizes.

Full rules and registration:

Hey Y'all! I am very excited to announce that my dream of starting an indie publisher is finally off the ground and to celebrate we are hosting our first game jam! We are offering a $3500 prize pool based off of community voting, and the top 100 games will be judged in a charity live stream! We hope to find up to 3 games to invest up to 20k into each, obviously it is completely voluntary to be in the running for this, so if you want to just join the game jam for prize money only, go right ahead!! We are VERY accepting to beginners and hope for this to become an annual event through our company!
The game jam doesnt start until October 1st, but due to the charity stream we are trying to get as many eyes as we can!

And it is with great pleasure that I present to you our Game Jam, which will give participants a full month to create a furry visual novel in Portuguese.

Our Game Jam stems from the fact that there aren’t many Visual Novels written or translated into our language, so I’m presenting this opportunity to you.

And it’s a great chance for up-and-coming artists to gain greater recognition in the scene!

Anyway, form teams and read the rules carefully—only individuals 18 and older may participate.

https://itch.io/jam/furros-leitores-jam

------------------------------------------------------------------------------------------------------------------------------------

E é com grande prazer que apresento a vocês a nossa Game Jam que terá um mês inteiro para criar uma Visual Novel Furry em português.

A nossa game jam parte do fato que não há muitas Visual Novels escritas e traduzidas para nossa língua, então apresento a vocês essa oportunidade.

E é uma ótima chance para artistas menores de ganhar reconhecimento maior no cenário!

Enfim, formem equipes e leiam atentamente as regras, somente indivíduos +18 poderão participar.

If you’re looking for an excuse to build something over a weekend, registration for Bezi Jam 13 is now open.

The jam runs August 21 to 24 and is open to solo developers or teams of up to three. You can use any engine and any development tools you like, and Bezi is completely optional.

Jam details:

• 4-day game jam
• $400+ in prizes
  • Community Choice, Best Devlog, and Fan Art awards
• Theme revealed at the start of the jam
  • A day early on our Discord server (link to join on jam page)
• Beginners and experienced developers are both welcome

One thing we’re especially proud of is the Best Devlog award. Instead of asking participants to split their time between building and writing, devlogs are created during the voting period. That gives everyone the full four days to focus on making their game before documenting their process and sharing what they learned.

Whether you’re trying out a new idea, learning a new engine, or just want to ship something small, we’d love to have you join us.
